Blood Test For Tsh And Free T4

Consult with countless people who are studying much regarding their low thyroid level symptoms. They view the symptoms as various illness and afterward “they have it,” whether they have been examined or not. This is one of the most difficult effects to master for a new medical doctor.

Please note that the symptoms allocated here are just to awaken interest. They mean nil until they go through the judgment of a qualified medical doctor. So here are some of the greatest common:

1. Chilly hands and feet when they should not be especially in the Summertime You have cool feet & socks just to snooze in.
Fatigued constantly even after Sleeping.
2. Can not lose Body Fat, even after relentless exercise & calorie counting in two to three weeks. It is cheaper for someone to catalog your Calore intake and monitor your weight fluctuation.
3.Constipation, together with substitute of various seeds and fiber to aleviate symptoms.
4. Brain blur, depression, that cutoff you from eating or miniature amounts of healthy exercise. This is common in low thyroid function patients
5. Ahead of time menopause or uncharacteristic menstruation. Difficulty with getting pregnant and loss of libido. Many women have excessive postpartum depression. I want to forewarn that numerous things can attain this. But be sure you have acceptable serum free T3, a convenient 24-hour urine test for T3 and T4. Not just a fair test lab. The urine should be checked by a picture spectrometer .. All alternative tests are very suspicious ..
6. High cholesterol, if the thyroid is low, as calculated by reasonable scrutiny, because the liver does not remove cholesterol from the blood and then you will be labeled as a heart patient, and prescribed lots of of undeserved chemicals that robbed you of your dollar and your vibrancy.
7. Now further symptoms occur, but exceptionally countless & do not suggest strongly enough that poor cellular function is the culprit due to the deprivation of adequate levels of T3 Keep in mind, you want to unearth your level of T3.

This is the essential approach to intercept low thyroid (T3). Examination of the patient. Where else will you discover a low thyroid level? In the beginning textbooks warned doctors with reference to the history and physical appearance a lot about lab tests. History suggests that is very sensible advice. All laboratory tests and X-ray studies with isotopes were investigated in approved low thyroid patients. Do you suspect what the results were? None. But the best of the worst was TSH. You remember the one who will signal the level of T4? The inactive thyroid gland .. T 4 You know, a drug companies sell to you while uneducated doctors Badmouth the natural pork balanced thyroid gland was discovered to be of advanced quality. This was published in the New England Journal February issue of 1999, should be assessed by examination. In general, this piece was on a small collection of thirty-eight patients, but a shocking conclusion from the addition of T3 has many patients feeling improved.

A list of low thyroid symptoms. Frosty extremities, eyebrows are thin or absent at the last 33% of the eyebrow. (Dr Heurtog signs from years before) Overweight (but I have found not far off from 15% of hypothyroidism patients are skinny .. Go figure), a poor pulse of around seventy or lower blood pressure, as have comments from a lot of ignorant doctors as an indicator of acceptable health or even worse, athletic competence. Ignore it, when it’s a low thyroid level symptom. Eyes are puffy under the covers, there is a bagginess. Skin is powdery & pale cream color. Nails are broken. The lower limbs have been blown up and do not dent when you push a finger and hold it for 1 minute. Commonly the thyroid gland is swollen and has a thumbnail, intermediate or large sized goiter. The first heart signal is not as prominent as the subsequent, and the person appears in a cloud. The ankle reflexes are almost always a repeated low or missing although the knee and elbow reflexes are ok.

Some doctors possibly will feel the thyroid gland. Anyone can inform you whether it is inflated. The gland will increase in an endeavor to create more TSH more if the body is low thyroid levels. This is not an specific discipline. I’ve looked & felt thyroid for over eighteen years, and it is even now not easy, the ultimate system to reveal whether the gland is raised, is to have an ultrasound done.

Categorically we’re afraid of thyroid cancer. They’re relatively atypical nonetheless. Also, there may be nodules on the thyroid gland, that call for a needle biopsy or even surgical requests. This is the realm of a surgeon and an endocrinologist.

Frequently Asked Questions

    Thyroid blood test: Normal TSH, slightly lower Free T4, anyone?
    I am 24 weeks pregnant and my doctor ordered a routine blood test for thyroid.
    I do not have any problem history or symptom, he told me this is a routine test.

    The TSH was very normal, while the Free T4 was slightly below the reference values. It should be between 12-22 and it was 11.

    He said that it is still normal, nothing to worry about.

    Anyone knows why i had a lower free T4?
    Any similar experieces?

    • ANSWER:
      Most patients with a low free T4 but normal TSH simply have lower levels of binding proteins but overall, thyroid function is usually normal.

      This could be why your free T4 is a little low. 11 isn’t really low enough to throw up any red flags.

    Thyroid Blood Test: Low T4 Free & Normal TSH Plus Symptoms of Hypothyroidism?
    Hi! I am a 25 yo female who has experienced unexplained weight gain (30 lbs before stabilizing), constipation, fatigue, amenorrhea, dry skin, etc., for the last several years. I have visited a GP, a nutritionist, an endocrinologist, a GYN, and a gastroenterologist, without any resolutions.

    Last week I visited a Naturopath and she was amazing. We are investigating blood sugar, adrenal, and food intolerance problems and meeting again in 3 weeks.

    I just received back my latest blood work and it shows my free T4 below normal at 1.42 (reference range is 1.53-3.85 units). My TSH showed up normal as it has on countless other tests. I had never been tested for free T4 before.

    Basically, I have almost every basic symptom of hypothyroidism and now I actually have a test result to back this up. As my past blood work has always been normal, doctors have seemed to disregard my very real concerns. This makes me nervous that they will overlook the free T4 results as well. Should I just wait to share the results with my ND (I am in NY but she can make diagnosis and write prescriptions because she is licensed in CT)? Or, should I see my general practitioner about this issue now? I really appreciate the advice!
    Thanks for your helpful answer af!! When I went to my endocrinologist she didn’t include the free T4 on the comprehensive blood panel. The ND I have gave me prescriptions for other blood work because she is licensed in CT.

    • ANSWER:
      I will suggest you to go to a good endocrinologist .

      Thyroid function test should be done at a good lab and your TSH should be measured by 2nd or 3rd generation assay method (also called sensitive and ultra-sensitive method ,respectively) not the first generation one.

      TSH is usually first line thyroid function test because it is most sensitive and specific indicator of thyroid dysfunction then free T4 (measured by equilibrium method not direct assay method as direct free T4 can have significant inter-assay variations).

      In almost all cases normal TSH indicates euthyroid (normal thyroid) status,
      except when there is problem with hypothalamo-pituitary axis. or when there is chronic starvation or severe illness which is rare and very much obvious if present .

    Is .7 for Free T4 blood test and 1.53 for TSH good levels?
    Don’t see dr. again till May. Just wanted to know. Thanks.

    • ANSWER:
      TSH – Thyroid Stimulating Hormone

      Optimal range 1.8 – 3.0 mU/L
      Typical reference range – 0.5 – 5.5 mU/L

      NOTE: TSH test can be “normal” with thyroid symptoms especially hashimoto’s thyroiditis (autoimmune hypothyroidism).

      Free T4 – measures the amount of free, or active, T4 in the blood.>>>

      Optimal levels 1.0 – 1.5 ng/dL
      Typical reference range – 0.7 – 1.50 ng/dL

      Slightly lower than optimal. Thyroid antibodies and free T3 will give a better picture of your thyroid health.

      Free T3 – best marker for measuring thyroid hormones available to thyroid receptor sites.

      Functional range: 300 – 450 pg/mL
      Typical laboratory range: 260 – 480 pg/mL

      Thyroid antibodies – used to determine autoimmune thyroid disease. The most common cause of hypothyroidism is Hashimoto’s Thyroiditis and the most common cause of hyperthyroidism is Graves Disease.

      Thyroid Peroxidase Antibody (TPO) – The TPO test measures an antibody that is found in most patients with Hashimoto’s Thyroiditis. This antibody blocks an enzyme that is responsible for adding iodine to a protein in thyroid hormone production. In clinical trials, the frequency of elevated TPO levels in patients with Hashimoto’s Thyroiditis was 90% compared to 64% in patients with Graves Disease.

      Typical lab reference range – 15 – 30 ug/dl
      Functional 18 – 27 ug/dl

      Antithyroglobulin Antibody (TgAb) – This antibody blocks a protein made by the thyroid that is necessary for making thyroid hormones, T4 and T3. It may also be positive in patients with Hashimoto’s thyroiditis.

      Typical lab reference range – 15 – 30 ug/dl
      Functional 18 – 27 ug/dl

    what do they look for on a routine blood test. My GP ordered a CBC w/ diff & plt, TSH & T4, free and a CMP?
    is this typical of what they order

    • ANSWER:

    Thyroid – Free T4 blood test interpretation.?
    Anyone shed any light on this? After some recent blood tests to ascertain thyroid function, my doc told me everything was normal, so I forgot all about it. However, I’ve since looked into what the normal ranges are for the tests she did, and now I’m a bit concerned about something.

    My TSH is 0.9 and I read that the normal range is 0.3 – 3.0, but my Free T4 is 16.8 and I’ve read that the normal range is 0.7 – 2.0.

    Am I missing something here? Has my doctor made a complete oversight or am I worrying about nothing?

    I went to see her about an inability to lose weight, despite exercising two hours a day and eating like a saint. I also have PCOS and have recently been put on Metformin, although wasn’t on any medication when these tests were taken.

    Can anyone confirm that the ranges I’ve specified above are correct, and if so, what might such a high Free T4 result actually mean?

    Cheers and thanks.

    • ANSWER:
      Get a copy of your labs. It will have your test results, and the normal range for each test. Every lab can have a different normal range. You can’t go by some normal range that you read somewhere. It may be completely different from the normal range your lab uses.

      When you get a copy of your labs, post your results with the normal ranges, and then we can talk about what they mean.

    Thyroid test. Free T4 and TSH. No T3?
    If anyone has any details on this please share.

    I’m going in to get my blood drawn for a thyroid test and I see on the sheet Free T4 and TSH checked off.

    I know there’s a lot of info regarding how TSH is highly innacurate etc etc.

    Anyway, with the test I will be getting, will the results be accurate enough to find out if my thyroid is an issue?? I fit almost every symptom described and have a family history of multiple different illnesses and issues.

    • ANSWER:
      Yes that is why the Dr ordered it. I have had these done and your Dr will read the test results and be able to determine if the numbers warrant another round of tests . There is some talk about the TSH but my Dr says it’s unwarranted and that is why they order the tests with the others to compare the numbers. Good Luck to You………………..KB

    What are the normal levels for TSH, T4 and T3?
    I recently went to the doctors for blood tests related to migraines, And i received a letter back saying i may need endocrine tests as I have abnormal thyroid function.
    My free T4 is 23.5pmol/L
    free T3 is 9.0pmol/L
    TSH <0.05mU/L Can someone interpret these for me and tell me whether these reading are severe or just outisde the "normal" levels.

    • ANSWER:
      These suggest thyrotoxic results and would require treatment.

    T3 is low, Free T4 and TSH are normal – should I be on T3 replacement Rx?
    I have been feeling unwell for over a year. I’m extremely fatigued, my body aches, I have concentration/memory problems, and feel feverish then freezing, among other symptoms. The doctors had thrown around several possibilities, including fibromyalgia, mono, lupus, and arthritis.
    Yesterday my doctor ordered several blood tests, including a thyroid panel.
    It came back with all as fine, except my T3, which was low. Here are the thyroid test results:

    T3 value – 62 (normal range 87-167 ng/dL)
    Free T4 value – 0.76 (normal range 0.6-1.6 ng/dL)
    TSH value – 0.97 (normal range 0.34-4.82 uIU/mL)

    My doc put me on synthetic T3 medication, which I started today.
    My question is – how is it that I have hypothyroidism, with normal T4 and TSH levels? From what I’ve read, T3, T4 and TSH all go hand in hand. Only my T3 is low.

    The diagnosis came from my general practitioner. Should I perhaps see an endocrinologist for a second opinion?
    I’ve been feeling unwell for quite some time, so I’d really like to make sure I have the right diagnosis, before I put medication in my body for potentially the wrong illness.

    Any insight would be greatly appreciated, as I’m entirely new to how the thyroid and related disorders work. Everything I’ve read thus far has provided conflicting information.


    • ANSWER:
      I had the same problem and saw an endocrinologist, who then referred me to a rheumatologist. I was diagnosed with lupus with (hyper) thyroid involvement. Hope that helps and hang in there!

    TSH 3.29 & 17 weeks pregnant?
    Hello everybody
    I really want to have ur opinion on this one since I’m worried as hell.
    I’m pregnant and my first TSH test result was 4.5.Two weeks later I tested my free T4 and TSH.TSH was 3.99 and the T4 16.
    I was given a half pill of Synthroid 25 mg.It’s been 3 weeks since I started taking the meds and I re-did my blood test.TSH was bit lower , 3.29 but still isn’t enough according to some.

    I don’t have any symptoms except the elevated TSH.I’m very worried for my baby.Is this hurting him/her?

    Any thought/opinion will be greatly appreciated.
    Thank you

    • ANSWER:
      Sorry I have no clue what you are talking about, as for meds check out this website. I used it alot when I was pregnant

    Thyroid test results… help me out.?
    I have always been treated for depression, mental issues etc with no luck. I finally looked up other things that could cause what I go through and hypothyroidism described a LOT of my symptoms. Even the more specific ones like very low pulse etc etc

    So, never getting any type of blood test before I went in and got a TSH, Free T4 and Lipids test.

    TSH – 2.1
    Free T4 – 1.0

    They told me the results are fine. I suppose after looking at the ranges, they might be. I know TSH is pretty unreliable, so I’m really checking with any knowledgeable others to see if my Free T4 is indicative of anything.

    I suppose its hard to believe all my symptoms would be coming from something purely mental and was wondering whether or not I should pursue more/further testing.


    • ANSWER:
      The T4 is a useful measure; it is the hormone in Synthroid & other thyroid hormone replacement medicines.

      Have you had a good physical exam with someone who is knowledgeable about both mental & physical health? Has anyone ever thought about something like chronic fatigue syndrome? IIRC, that can have some of the symptoms you’re describing and its symptoms are both mental & physical.

      The only thing I can suggest is to talk to your primary care provider and ask what might be causing the constellation of symptoms you’re experiencing. You don’t necessarily have to talk to a doctor; in fact, a Physician’s Assistant or Nurse Practitioner or an experienced RN might have more time to talk to you about your concerns. Another avenue might be if your health insurance provider (or some other resource in your community) has an information line.

      I guess the bottom line is that none of us can tell you whether or not to pursue more testing. You have to be the one to decide that, in conjunction with your health-care provider(s).

    what tests should I get done to check for hypothyroid?
    I am tired all the time and have a lot of the same symptoms that go along with hypothyroid. Should I eat the morning of my bloodtest? I think I’m going to try to get a TSH and free t3 and t4 test…If this is just a regular appointment with my physician, could I get a TSH blood test that day? or do I have to have it a different day? Any information would be great, thank you

    • ANSWER:
      I work in a doctors office. Normally for Thyroid tests, you don’t have to “fast” before taking the test. That means you can eat a normal “light” breakfast. If your doctor appointment is in the afternoon, you can also have a normal lunch. Best not to eat a “heavy” breakfast or lunch.
      The doctor will normally order a TSH, Free T3 & 4, some doctors will also order a T3 Uptake. Depending on your insurance the blood can be drawn at the doctors office, then sent to a lab, or they will send you directly to the lab to have the blood drawn. Some doctors office’s don’t “do” blood in the office, they send all their patient to the lab. You can still do this the same day as your doctors appointment. Most labs are open late in the evening.
      If you tell the doctor your symptoms, he may decide you need other tests. There are several things that mimic the symptoms of hypothyroid.
      Good Luck, Hope you feel better soon, and your doctors visit goes well.

    How long does it take for changes in levothyroxine dose to show up in the bloodstream?
    Hypothetically if one were to drop from 75mcg to 25mcg a day, how long would it take for that drop to show up on a blood test, for Free T4 and TSH levels?

    • ANSWER:
      It would depend on the amount of natural thyroid function you have, and how good you are at absorbing the oral dose of T4. Your T4 dose should show up as lowered pretty quickly, but the TSH might take weeks to months to rise, depending on the function of the thyroid.

    What do these blood test codes mean?
    My daughters doctor gave me a lab slip today and I was wondering what they were testing for. The codes are…TSH, Chem-Comprehensive, Tissue transglutinase autantibody, IGA, ESR,T4 Free, cbc with diff. If you know what any of these mean please let me know, I’m worried about my daughter.

    • ANSWER:

      This site will explain better than any of us can what the doctor wants to know and will explain it in language you can understand.

    Do low T3 and Free T3 values indicate hypothyroidism?
    Recently I’ve been experiencing symptoms such as hair loss, fatigue (I need an espresso shot w/my coffee or I can’t concentrate), and it is becoming harder and harder to lose weight (I need to limit my calories to 1200-1300 to see ANY results and I am around 130lbs).

    In April there was a blood test conducted that indicated my TSH, T4 and Free T4 levels were normal, whereas my T3/Free T3 were low. Now I’ve repeated this test in August and ALTHOUGH all of the levels are normal now, the T3 and Free T3 are only marginally normal. My T3 for example is at 34.00 ng/mnl on a scale of 32.00+.

    I am female.

    Please give me your thoughts.

    • ANSWER:
      You did not say what your TSH was (many doctors do not go by right guidelines. Many doctors also do not test for antibodies and should.

      You need testing for thyroid ANTIBODIES as well as TSH. TSH ‘norm’ should be .3 – 3 (w/ most feeling best at < 2) but would not matter if ANTIBODIES are present. Indicative of Hashimoto’s Autoimmune Thyroiditis…main cause of HypOthyroid & is worse (...OR Graves Disease - HypERthyroid). WARNING: Doctors seem not to want to find/treat thyroid disease. You may have to go to more than one doctor before you get the right tests, interpretation, and treatment. Best wishes. Ck these: God bless

    Need help in understanding my blood test! Can anyone help me with these abbreviations and what they mean?
    My best friend is a lab tech and recently did full blood work on me (regularly costs about ,000) that tested everything for free. We were just doing it for fun… He told me about it there but now I’m looking at it at home and don’t remember what any of these things meant…

    Define any or all of these please! Thanks

    EC02 was high
    CK was high
    PTN was low
    LIP was slightly high
    GGT was low
    ALP was very low
    TSH was low
    T4 was very low
    DGNA was low
    PHOS was low
    ALT was very low
    CA was low
    CREA below asy rng
    AST was very low
    dbil was below asy rng
    IBCT was below asy rng
    TP was below asy rng
    GENT was below asy rng
    HIL was abnl assay
    I can find the abbreviations… I am mainly wondering if anyone knows if any of these things are bad news…

    • ANSWER:
      EC02 was high — it looks like it deals with occult blood, or parasites etc.
      CK was high — creatinine kinase — in muscles, kidneys, and heart
      PTN was low — deals with tumors
      LIP was slightly high — fat profile
      GGT was low — liver enzyme
      ALP was very low — liver enzyme
      TSH was low — thyroid stimulating hormone
      T4 was very low — thyroxine
      DGNA was low — levels of digoxin in your blood
      PHOS was low — phosphate
      ALT was very low — liver enzyme
      CA was low — calcium
      CREA below asy rng — creatinine
      AST was very low — liver enzyme
      dbil was below asy rng — tests bilirubin levels
      IBCT was below asy rng — blood transfusions
      TP was below asy rng — total protein in your system
      GENT was below asy rng deals with blood pressure, and with functioning of lungs
      HIL was abnl assay — testing for parasites

      It looks like they were testing you for liver function, lung function, and the general functioning of the blood, and of your body. They are also testing for parasites, and other sort of toxins within your body as well. I hope that this helps you.

    Can someone please shed some light on my thyroid test results?
    Hi there,

    I have been having almost all of the symptoms of hypothyroidism on the standard lists, increasing in intensity over the past six months, and my mother has it.

    The first blood test was for TSH and a blood workup a couple weeks ago. It showed:

    TSH = 5.48 (normal: 0.5-5.5 <--I hear that is an outdated range) Iron deficiency anemia: I mention this because I hear it can be linked with hypothyroidism Based on that, my doc sent me for new blood tests today. Results: Free T4 = 18 pmol/L (normal: 11-22) Anti-Thyroid Peroxidase = 26 kU/L (normal: <35) Can anyone shed some light on what might be going on here or offer any theories? Is my thyroid plain ol' normal? Should I be pressing for any specific tests as follow-up, or ask any specific questions of my doctor? I have a follow-up appointment in a couple weeks. Thanks for any responses!

    • ANSWER:
      You are HypOthyroid! TSH ‘norm’ should be .3 – 3 (w/ most feeling best at < 2). Here is some info: TSH would not matter if ANTIBODIES are present. Indicative of Hashimoto’s Autoimmune Thyroiditis (cycles between hyper & hypo at start)…main cause of HypOthyroid & is worse (...OR Graves Disease - HypERthyroid). YOURS SHOW OK (unless those ranges are wrong too :(

      WARNING: Doctors seem not to want to find/treat thyroid disease. You may have to go to more than one doctor before you get the right tests, interpretation, and treatment. Best wishes.

      Ck these:

      p.s. you should not have to wait a couple of wks to start meds (Synthroid or similar). Also the doctor will have you retest approx ev 6 wks to start to get the levels right. Then you will go every 6 mos then on. If this is NOT going to be done, you need a new doctor!

    Does marijuana effect the following blood/urine test (liver functions)?
    I have juvenile rheumatoid arthritis and am currently on methotrexate, a low dose chemotherapy that has controlled my disease well. I abstain from alcohol like my doctor says, but want to know if pot effects the blood and urine tests I get each week, so I don’t get a false positive for something. All of these tests are for liver function, kidney function, and autoimmune disorders. I just want to know if pot will mess them up.

    *Just want to know if my blood test results could be related to how I feel*
    I am 27 and now I weight 60! I used to weight only 52. I am 1 meter and 59 cms tall. Thank you for your help
    I know it is called subclinical hypothiroidism, but I’d like to know what you think please
    8 kilos is like 20 pounds
    I couldn’t find the reference ranges, that’s all it says
    These results are from February, so I will try to get a new blood test, it is just so expensive!

    • ANSWER:
      It would be best if you could also post your reference ranges (as different labs and countries use different ranges). Nevertheless, you definately have hypothyroidism and should get treated.

      Serum free T4 level = 15.8 pmol/L
      Serum TSH level= 5.9 mu/L High

      Let me explain these 2 a little in basic terms.
      Free t4 is the actual thyroid hormone. When you have hypothyroidism you are replacing this. Without the lab range its hard to know where exactly you stand with it but I’m guessing its around 10-22. Even though anything between this is considered “normal” optimal levels are in the upper third of the reference range (ie. people feel best when t4 is this and many dont feel well at all unless they are at their optimal value).
      TSH: this is basically your brain sensing that you are low on thyroid hormone and shouting to your body to make more! Your body is responding by making more. This is why your free t4 is normal at the moment and your TSH is high (ie. your body is shouting out for mor e and TSH rises whilst your has responded to this shouting by making enough Free t4 to keep you in normal range). For now at least.

      Thyroid peroxidase antibody level= 8 iu/mL
      Anti Thyroid Peroxidase IgG Antibodies
      Anti TPO IgG antibody – Negative (Normal range: 1-50 IU/ml)

      The presence of antibodies is used to confirm that the hypothyroidism is caused by hashimotos thyroiditis (the most common cause!). This is basically your immune system attacking your thyroid so that it cant make enough hormone (hence its called underactive thyroid). You’re not supposed to have these antibodies at all but approx 10% of healthy euthyroid people have them anyways. You’re negative for 2 of these and very low on the other so I think this means that you do not have hashimotos. I’m not 100% sure on that though.

      Your symptoms are definately not a coincidence! I dont know much about kilos but I gained 20lbs in 8 weeks before I was diagnosed. I also was putting other symtoms down to other things. Actually the only reason I was checked was because my periods had stopped. I’m only 23 by the way!

      Through reading forums online etc I’ve definately seen that the symptoms of hypo dont always correlate with peoples numbers ie. someone with subclinical can feel much worse than someone with primary. Symptoms are more important than numbers, though maybe not in a doctors book! I hope that your doctor has presribed medication with those results.

      I hope this info has helped you, if you need more help I recommend you post your question here:

      Its a great forum especially for thyroid disorders with some people who really know their stuff and would be more than willing to help/explain anything you may want to know.

    How do I get my TSH levels to show?
    I have Graves Disease and my recent blood tests were as follows:

    Free T4 – 11

    TSH – not detected

    The receptionist gave me my results over the phone and asked me to make an appointment to see my doctor for next week.

    Last time I saw my Endocrinologist he said he wanted to see some TSH before he can put me forward for RAI.

    Now that I am behaving and doing as the doctors tell me – I really want to get things right. I have been on various websites but can’t find anything specific about Thyroid blood test results.

    So how do I get my TSH levels up?

    I take it I’m no longer hyperthyroid either, so am I normal (whatever that is)?

    • ANSWER:
      Patients with hyperthyroidism have suppressed TSH because of their high T4 levels. I assume you are now on carbimazole, this is suppressing your T4, which is now subnormal. This would normally result in a rise is T4. This has not yet happened.

      Do not be an idiot and play about, just wait for you body to adapt to its current situation.

    Can stress cause a high TSH?
    I’ve been having my thyroid tested (TSH and T4 free) for 5+ years because of both hyper and hypo symptoms. Always normal until my latest TSH test on 2/9. Normal ranges are 0.27-4.2. My result was 5.10.

    I was nervous at the time because of other medical issues (neurological).

    And, no, I don’t have any answers yet regarding any of this.

    I’m 22, 5’7″ and my weight goes from 105-115 a few times a year.

    Lots of blood work was done on Friday and everything looked fine except the high TSH.
    apparently some of you missed where I said my tests were always NORMAL until this LATEST test was taken.

    I never had a dx of thyroid disease… ever. again I’ll say my tests were always normal.

    on 1/17 my result was normal. 2/9 high.

    I hope I’m making myself clear.

    I use plenty of iodised salt… its the only kind my mother buys.

    I guess it was stress.

    • ANSWER:
      Stress can have various effects on the body via the PNEI axis (Psycho-Neuro-Endocrine-Immune axis). Thus, Psychological stress can trigger the immune system dysfunction via the above-mentioned process and cause high TSH.

      High TSH (Hypothyroidism), in many cases, is primarily caused by immune dysfunction (apart from Iodine deficiency).

      If your TSH level was high due to some stressful condition, it should be nearer to normal on rechecking after a couple of months. Meanwhile, improve the iodine intake in your diet (Use Iodized salt only) for the next 3 months and recheck your TSH levels. If they turn out to be normal, it means you probably also had an Iodine deficiency.

    my thyroid levels appear to be normal but I am losing hair at age 21… can someone help?
    there is no baldness in my family. my hair loss is kind of a strange also, seems to just be thinning all around. mostly on the whole top of my head though.
    most recent blood tests show
    tsh 1.94
    t4 9.3
    free t4 2.7
    t3 total 114
    t3 uptake 29
    althought the blood test appears normal I am severely underweight- I am 6’1″ and weigh 145 and find it almost impossible to gain weight. my dad’s side of the family has thyroid issues.also my enegery is really low.
    what do these symptoms mean?!
    thanks for reading

    • ANSWER:
      Body hair growth (or loss) patterns are genetic, so assuming you are healthy and not taking any drugs that may affect your hair growth, you need to look at the men folk on your mother’s side of your family, because the gene responsible is passed on to you on her X chromosome.

    Reading Blood Test Results?
    I had blood work done to check my thyroid and i don’t understand them….

    Thyroid Peroxidase (TPO) AB 325
    it says 0-34 is normal..

    T4,Free(Direct) 1.22 normal:(0.61-1.76)

    TSH 3.193 0.450-4.500 is normal

    anyway the first one’s more important….she is referring me to “endocrine” (i guess endocrinologist) soo what could this mean for me??? wat should i expect?


    • ANSWER:
      Thyroid peroxidase is one of those tests that often means something is going on, but no-one knows if it means anything. Usually in the absence of disease they will just do some follow up labs later on. I would definitely keep the endocrinology appt, but not lose sleep on it.

      ( not a real doc, just play one on TV)

    My wife has just had some Thyroid Function blood tests done. What is a good range?
    Her Free t4 was 9.1 pmol/l which was within the reference range
    Her TSH was 1.96 uU/ml which was within the reference range
    Her Free t3 was 3.5 pmol/l which was lower than the reference range. I have checked the internet and 3.5 seems ok for a 31 year old lady.

    We are moving to Australia and worried this may effect us getting a visa.

    • ANSWER:
      TSH normal is from 0.35 – 5.50
      T4 FREE normal is from 0.7 – 1.6
      T3 Free normal is from 2.3 – 4.2

      So she falls within normals for all tests.

    What are my thyroid results mean? Confused!!?
    I was called in a few months ago to my doctor because my blood work came back abnormal. In July my TSH was 5.23 (0.35-5.00) and my FREE T4 was 14 (10-20) then I was retested in September this time my TSH was higher 5.82 (0.35-5.00) and my FREE T4 was 14 (10-20). Another retest this time my TSH 2.77 is within normal limits, they never bothered to re-test my FREE T4 again. The one doctor said it was perfect and to only re-test once a year, then I got a second opinion and he said that I should still be monitoring it every other month. This month I am extremely fatigued and anxious. Do you think this has anything to do with my thyroid after all? I keep getting different answers from different doctors and it’s stressing me out. The doctor who told me to get it retested scheduled me today for another blood test including the TSH and FREE T3 and T4! What does it mean when your TSH rises and your T4 is the same? I can only assume this month my T4 will remain the same perhaps?

    • ANSWER:

    confused about thyroid test and feeling ill?
    I recently had a TSH and Free t4 test done because i just do not feel well. I am swelling, cold all day long and then sweat all night, all around tired,chronic sinus and skin infections, exhausted yet have trouble sleeping at night. These symptoms made me think I might be hypo but I got my test results back and they are not what I had thought.

    TSH 1.49
    FT4 is .85 …Dr says my blood work is absolutely perfect I thought ft4 was on the low side and find it a little odd for my tsh to be where it is and my FT4 to be on the low end of normal..Am i wrong? Is it possible my tsh is wrong? my dr is sort of an ass but do to insurance I am stuck with him.

    I want to pay out of pocket for a thorough thyroid work up…can order it on line do my numbers give just cause to spend the $$$
    I am a 39 f. I am tall, big boned and about 70 lbs overweight though i do not eat much at all. I should also add I ache all over my joints my muscles my feet burn and tingle…

    • ANSWER:
      Hi Amy. A TSH test alone, is not the best way to diagnose a thyroid problem. My TSH was in the normal range when i was diagnosed. You need to get these 4 blood tests done. TSH, T3, T4, and most important, an Antibodies test. That’s the one that doctors sometimes ignore, so you have to insist on having it done. All of your symptoms do indicate a thyroid problem. Getting a second opinion is always a good idea when dealing with this. I went to 3 different doctors in the beginning ( and they all said different things ). It did turn out to be my thyroid. I get my own blood work done online at HealthcheckUSA. There are other sites also, but they are the cheapest. I just had them done 3 weeks ago, and paid .00 ( going through my doctor, it was 0.00 ). As you see, you can save a lot of money, and the results are sent right to you, so no waiting for the doctor to give them to you. Your T3 and T4 should always be mid-range or little higher. If it is way at the low end, or way at the high end, there’s a problem. If your antibodies are high, then you most likely have an autoimmune disorder. Do your own research on the net. You have to educate yourself when dealing with a thyroid problem. Doctors will not take the time to do it. I’ve spent hours on the internet learning about this disease, so i won’t be blown off by the doctors. Good luck, and be sure to get your tests done. Take care :-)

    CBC & CMP Blood Tests(thyroid problems?)?
    Do either of these help diagnois a thyroid problem? I tried to get my dr to do the free t3 and t4 but they wont they say the t4 and t3 uptake is the same thing even tho iam on birth control and my t4 came back slightly elevated as did my FTI.They are trying t say I might have hyperthyroidism I just want them to do the necessary tests to make sure but they dont seem to care they just want to send me to this specialist without even knowing 4sure something is wrong.My main concern is my excessive hair loss and I cant get an appt. with the specialist untill august.I had to demand a TSH test and they finally did that but wouldnt budge letting me have the free t3 and t4.Instead the sent me for a cbc and a cmp which I am not really sure is relivant.
    They did a t4 and t3 uptake and FTI on me first my t4 and fti was sightly elevated.I hen read online bc pills can cause them to be high and read about tsh and the free t4 and free t3 I called and asked my dr to do that but they said it was the same thing.I did however get them to do the tsh and thats when they sent me for the cbc and cmp not exactly sure why tho all i need is tsh-free t4 and free t3.Im starting to think i know more than them..I havent got my tsh back yet.

    • ANSWER:
      You ae correct about the free t4 and free t3 test. These are the best thyroid tests to have. A T3U is worthless. A TSH can diagnose the problem, but the fre tests are the better choice. CBS and CMp will not show a thyroid problem. If they still have a sample of your blood and its been under a week, they can do further testing. I;d advise a Free T4, Free T3, TSH, and antibody test

    What does abnormal T3 levels mean (but normal everything else)?
    What could it mean if I have abnormal T3 (uptake and total), but normal TSH and T4 (free and total)? I have had a condition called Hashimoto thyroiditis, and my thyroid antibodies are always high.

    (My doctor ordered some additional blood tests, but I am just wondering in the interim what this could mean)

    I have been struggling losing weight and have been gaining for a while now.


    • ANSWER:
      Was your T3 low or high? You might be experiencing hypothyroidism, due to your autoimmune disease.

    Is it possible to still have an underactive thyroid even if the TSH level is normal?
    I was dignosed in 2008 with hypothyroidism for which I was successfully treated, my thyroid gradualy got better with time and I was taken off Levothyroxine. Medical proffesionals put it down to pregnancy. I had another child in 2009 and started to feel terrible again, I also moved to a new area with different doctors, I requested a new blood test and it came back with a TSH level of 2.11 (this is considered normal) though at the high end of the scale. She did not test my free T3′s and T4′s. Can someone please tell me why this is? and also does anyone know if it is still possible to have an underactive thyroid with a normal level of TSH?

    I am from the UK… I know different areas have different result meanings. ( this is STUPID) why cant every lab have the same result meanings?

    • ANSWER:
      The problem is that your testing has been inadequate. TSH alone is no more than a screen test. If disease is suspected or has been previously identified, T3, T4 and thyroid antibody also need to be checked. Most thyroid disease is due to an auto immune condition, previously known as Hashimoto’s auto immune thyroiditis. It can produce both over and under activity and requires constant monitoring.

    High tsh 5.82–hypothyroid? Is it causing my problems?
    I just went to the doctor and got a copy of my blood test (it is from April 2005, but its the only thryoid test I’ve gotten). This is what it said
    TSH: 5.828 uIU/mL
    Free T4: 1.01 ng/dL
    T4: 10.0 ug/dL
    Isnt a 5.828 a really high TSH? My lab sheet says that the normal range is .360 to 5.8. Isnt it from .3 to 3?
    I am going to the endocrinologist on Monday to do another test…I wonder if it will be better or worse?
    I think my symptoms are getting worse though. I keep getting weird headaches, cant concentrate, all my muscles ache and I toss and turn all night because of it, and today in the store my hand got a little tingly like it was going numb. I also have had irregular periods (they actually stopped completely for about a year), I have bald spots on the front of my head, I am always tired, fatigued, have anxiety and slight panic attacks every once in a while, and I just feel like such a lazy person
    What do you guys think–hypothyroidism causing my problems?

    • ANSWER:
      The lab reading, as far as I am aware is correct. The slighlty raised TSH is suspicious of hypothyroidism even though your t4 is within normal range. Sometimes when you do a thyroid function test you may catch the condition when it is changing and may not be conclusive and has to be repeated in 2 months or so. Given your symptoms thyroid disease is a possibility but the symptosm are so non specific that it could have other causes. i’m sure your endocrinologist will get to the bottom of this and help you recover.

    Can anyone tell me what my recent thyroid blood results mean?
    My Free T4 = 14pmol/L
    T3 = 2.3nmol/L
    TSH not detected
    My free T4 and T3 used to be a lot higher when I was mega Hyperthyroid.
    I had these bloods done at hospital and received a letter from my endo telling me to continue with 20mg carbimazole daily and see my GP in a month for another blood test. Endo did not explain what results meant. I am so tired and feel awful. All endo can say is he wants to see some TSH. HELP please.

    • ANSWER:
      Still hyperthyroid.

    Scared about getting blood drawn.?
    On Monday, I’m getting my blood drawn and tested for: Basic Metabolic (CHEM 8), CBC, Platelet, and Diff, Sed Rate, Iron & TIBC, T4,Free, TSH, and under additional tests it says :Prolactin.
    This is my first time getting blood drawn. I’m really nervous, which is weird because, I will get any piercing with no anxiety what soever, I will help handle blood, and I will watch an autopsy, but I’m afraid of getting my blood drawn.
    I’m mostly afraid of passing out, even though I know it won’t be as much as when you donate blood (which I’ve also never done). I’m just being my worrywart self.
    Could anyone prepare me a little for it? I’m just nervous.

    • ANSWER:
      I have had tattooes, piercings, two kids, and blood draws STILL freak me out.

      OK, here’s the thing… drink lots of water! It makes your veins easier to draw from.

      Second, do not psych yourself up over it… the reason people pass out from blood draws is because you are so panic stricken over the procedure. I have a friend who is a nurse and she explained to me that your body perceives that it is in danger during a blood draw if you are anxious over it. Its called a vagal response. Your body will shut down “non-essential” functions to save itself… if you call standing up non-essential. However, here is the trick… if you are controlling the feeling of freaking out… you can control the feeling of being in charge of your bodies response. Say positive things to yourself… and don’t look.

      You will be ok! DO NOT think you are going to pass out. Think instead that you are in control of your body and that you are ok! You are not in danger.

      IF you feel light headed afterward, ask for juice. It will regulate your blood sugar. Most places will let you lay down, they are really used to that.

      Don’t be nervous. Be matter of fact and you will get through it and on with your day.

      Good luck!

    “Borderline” hyperthyroidism: is it real? And how can I help myself? My Dr. won’t?
    I just posted a Question on how I have a lot of hypoglycemia-type symptoms if I skip a meal, yet any time I have my blood sugar (glucose) tested, even after a 12-14 hour fast, the glucose is 100% NORMAL. I’m hoping some folks have insights on that. Now another question…

    I have common symptoms of hyperthyroidism (overactive thyroid/too-fast metabolism), yet my blood tests always come back in the normal range. My main symptoms are not being able to gain weight no matter how much I eat, and extreme intolerance to heat. I also often feel kind of hyped up/anxious and have periodic insomnia. My Dr. thinks all these things (except the heat part) are an anxiety disorder, but I don’t know if I agree.

    I’ve had several tests for TSH and free T4 (or T3?) over the years, and nothing is ever out of line. HOWEVER, the numbers usually lean towards the “fast” end of things, rather than the “slow” one.

    Is there such a thing as “borderline” hyperthyroidism? If so, how can I help myself?
    Thanks, Answerkeeper, for your insulting, holier-than-thou reply. I asked ONE question pertaining to hyperthyroidism — how is that “flooding” the forums? LOL! Perhaps you have double vision? Or perhaps an echo in your brain? My other question was about hypoglycemia. Even if you thought those were the same thing, that would still be only 2 questions, not a “flood” of them. Stop acting like a critical, nagging schoolmarm when someone is not feeling well and asking for help. And I am NOT a hypochondriac. They enjoy having illnesses and try hard to “find” something wrong even if something isn’t wrong. I am the opposite. I HATE having anything wrong and will seek any/all remedies to become well and to keep my body in balance. I’m very sensitive/knowledgeable about my body and can tell when it’s not running right. That’s all. I’d appreciate if you didn’t reply, if you’re going to pepper your reply with insults when you don’t even know me!

    • ANSWER:
      I have hypothyroidism and my TSH and T4 are way out of range, but when I was pregnant I was borderline but my symptoms were well I had no symptoms and the doctor told me she treats the symptoms not the numbers so if you are having the symptoms Id talk to another doctor.

    Do I have a Thyroid problem?
    For the last few weeks, I have been experiencing anxiety, nausea, vomiting, loss of appetite, fatigue, ect. I got a blood test and and upper gi. The upper gi test came back normal, but I’m not sure about my blood test. My TSH level was 2.040 (0.530-3.590 range) and my T4, Free(direct level) was 1.96 (scale of 0.93-1.60). Can anyone help me decipher what’s wrong with me? Thanks.

    • ANSWER:
      Donßt sounds much like a Thyroid problem. But I would consult a doc.

    I need help in understandig what my thyroid test means?
    4 months after giving birth i developed a low thyroid according to thyroid tests, i also had a goiter. i was perscibed thyroxine 100µg within a week of being on this i developed depression extreme nxiety and feelings of over whelmness. doctors said it was other problems non related. for 4 months i carried on taking the 100 the docs wld not drop me to a lower dose saying i was fine. needless to say finally a doctor listened and brought me down to 75 µg thyroxine. symptoms of depression has disserpeared i am no longer emotional, no and my anxiety has plumeted froma 10 to a 4 ratio and the over whelmness has reduced greatly to a 3 out of a 10 ratio. i have recently had another blood test to check my thyroid levels as im still not 100 per cent happy with the way i feel ie very mild anxiety im hoping that if i was reduced again to a lower level my symptoms will completely go as i have never had such symptoms prior to this thyroxine.

    my recent test results are: as set out on paper
    units ref range
    free t4 — 17.1 — — — pmol/L (10.0-19.0)
    tsh 3.31 0.42 — — –mIU/L (0.50-4.00)

    plse explain doc says im still slightly high and will wait to see in another 8 weeks. another doc says yes still slightly high prefered goal is 1. he recommended that i take the thyroxine 75 one day then the 50 the following day and vice versa as apposed to taking the 75 which i have been on for the last 2 plus months
    that makes sense with wat you are saying, i thought it was okay to take thyroxine prior to testing??? also would you class my results as hyper or hypo

    • ANSWER:
      A goal of TSH at 1 is good advice. Which is your current TSH? 3.31 or .42? .42 is fine as long as your FT4 (and FT3) are normal, and your’s is. If you are having hyperT symptoms at this level, alternating the dose as the dr suggested is the right thing to do. that will probably bring you up around 1 or so.

    What do these results mean?
    Hey I just got some test results back I’m just curious on what they could mean I’m seeing the cardiologist about it on Monday but just too anxious haha
    so I’m a male age 23 wt 250lbs height:6ft If you needed to know so here it is I’m only gonna post the abnormal ones so. Thought I should add not on any medications I do have a lump I believe on my thyroid gland as well.

    thyroid test

    TSH – <0.01 free t4 - 26 ( refrence range max was 22 ) 24 hr urine collection creatinine - 18.8 mmol/colln.period ( ref range 7.0 - 18.0 mmol/d ) dopamine - 3310 nmol/colln.period ( ref range 400 - 3300 nmol/d) aldosterone renin test ( had to be active for 3 hrs prior to test and sit for 30 mins before test blood taken at upright position ) aldosterone random - 1217 pmol/L ( no range given just consistent with secondary hyperaldosteronism and than it gives a list of diffrential diagnosis) renin random - 0.78 ng/L/s ( ref was 0.05 to 0.55 ) well that's it just curious of what it can all mean thanks.

    • ANSWER:
      These results are just explaining the test findings to you, or the doctor reading them. Usually the blood will be read first and then a Radiology doctor reads them and finally sends them on to whatever doctor ordered them for you to take. As you can see, there’s no mystery surrounding them as long as you know what the results are all testing for. Most people only need to wait until their doctor explains them to them too. Why not wait a few more hours and make everyone involved happy? By then they can all be read to you before you even leave the doctors office. Good luck and God Bless

    Hypothyroidism – what do I have to do to get my British GP to take my TSH result seriously and DO something?
    In May 2007 my TSH was 4.08 (parameters were 0.30 to 4.5) but now my TSH is 6.45 (parameters now 0.5 to 5). The Free T4 is 13.1 (within normal parameters). No Free T3 done.

    I have been suffering from fatigue for 18 months. It is now so bad I am unable to do more than 9 holes of golf and walk (on the level) for an hour. Last year I was up and down mountains in Andorra and playing in golf competitions every other weekend. By 3 pm I am exhausted and there’s a standing joke at work not to ask me to do anything after 3 pm. I can’t sleep at night for worry and also for pain from my joints – a worrying condition that zapped me out of the blue 6 weeks ago (awaiting blood test results on my immune system).

    My GP refuses to acknowledge I have a problem worthy of attention. “Come back in 12 months if it gets worse” attitude. Do I have to wait till my thyroid completely packs in before anyone will do anything? Am I supposed to put up and shut up? Why are British GP’s so resistant to treating thyroid problems? I have an identical twin sister who’s had an underactive thyroid for years. Why is no-one listening?
    This is not a gender issue. The last 2 doctors I saw were female. Also, I cannot afford to go private – and why should I when I’ve paid income tax and full NHS contributions for 40 years? Furthermore, I’m on low income (but not low enough to qualify for finacial assistance).

    From the research I’ve done it seems that UK GP’s simply don’t know how to diagnose the blood test results properly. If there are any GP’s out there who can tell me otherwise, I want to hear from you!

    • ANSWER:
      I have to say those results don’t look obviously hypothyroid to me, and I don’t know any doctor, whether GP or specialist, who would put you on thyroxine with a TSH at that level. In fact I think it would be pretty irresponsible. According to the UK thyroid guidelines (

      “If the serum TSH concentration is above the reference range but <10mU/L, then serum thyroid peroxidase antibodies should be measured. If the serum antibody concentration is high, then serum TSH should be measured annually or earlier if symptoms develop; thyroxine therapy should be started if the serum TSH concentration rises above 10mU/L. If the serum antibody concentration is not raised, then repeat measurement of serum TSH approximately every three years is all that is required" "There is no evidence to support the benefit of routine early treatment with thyroxine in non-pregnant patients with a serum TSH above the reference range but <10mU/L. Physicians may wish to consider the suitability of a therapeutic trial of thyroxine on an individual patient basis." With an identical twin sister who is hypothyroid, that greatly increases your chances of developing it. Your doctor should bear this in mind. Also you have to treat the person, not the 'numbers'. However, don't be too hard on your doctor for not giving you thyroxine. She/he may have good reasons for thinking your symptoms have nothing to do with your thyroid, and I think it's the sign of a good doctor if she refused to just write the prescription you asked for. In my experience, British GPs are very good at interpreting thyroid tests (since they see so many of them!), and they tend to call a specialist to ask for advice if they are at all unsure.

    Hypothyroidism symptoms, normal tsh?
    I am 20 years old and have dealt with hypothryoid-type symptoms for the past 3 years. Symptoms started appearing about a 6 months to a year after a series a very bad nose bleeds so I’ve always felt that my problems stemmed from these nose bleeds. My symptoms include imparied cognitive ability (concentration/focus/memory/foggyness), dry skin, sensitive to cold weather, inability to gain weight/muscle mass, brittle hair, heart palpatations, sensitivity to light, and knee/joint pain (diagnosed tendonosis), and some other symptoms. Over the past six months, I have tried to figure out what is wrong with me because originally I didn’t percieve these symptoms as a problems. When I told the doctor about my symptoms, particularly the cognitive issues, he recommended I got so a psychologists for ADHD analysis.
    Well, since then I haven’t bothered with my GP because of frustration and have had several blood tests to hopes of finding something. Initially, I didn’t suspect or know about hypothryoidism. I’ve had my tesosterone and IGF levels checked and both came back normal, although testosterone was alittle low. Lately, after looking at possible underlying causes of dementia, I’ve read about hypothryoidism and can really relate to most if not all of the symptoms I read about. However, my TSH has been checked with all of my other blood work because I assume it is protocol these days. It came back at 1.5 which seems to be optimal. There is, however, other descrepancies in my blood work. My Neutrophil % is low, Lympocyte % high, low HDL (24, 19, 30, respectivley) and a high bilirubin count which my doctor called Gilbert Syndrome.

    Should I get my free t3 and free t4 levels checked or is TSH pretty realiable for diagnosing hypothryroidism? Any suggestions are appreciated…

    • ANSWER:
      Yes, you should have the T3, Free T3, T4, Free T4 tests done. Sometimes a thyroid problem can still occur even in spite of a normal TSH level.

      I would recommend getting an opinion from a hormone specialist called an endocrinologist as well to see what they think could be going on.

    I have hypothyroid but my new doctor doesn’t believe so?
    In August of 2009 I was diagnosed with hypothyroidism. I was put on Synthroid and my levels returned to normal. In July of 2010, I lost my insurance because it was TriCare/military through my dad and I turned 23. I only had enough synthroid to last me through October of 2010. By April of 2011 I had new insurance and requested my TSH levels be tested so I could get back on Synthroid. However, my new doctor said my thyroid levels were fine and if I wanted I could get another blood test in a few months. Since then I’ve had accelerated hypothyroid symptoms. In January of 2011 I started having severe vertigo. Now it’s up to every 2 weeks I get really bad vertigo. It was only recently I found out it was a symptom of hypothyroid. After gaining 30lbs since November, 2010, I began a weight-loss program 3 months ago, and despite following the nutritional guidelines and incorporating moderate exercise, I’ve only lost 9lbs. For the past month I haven’t lost any weight. My face is bloated, my skin is dry, my hair is brittle, I’m extremely moody and I have trouble sleeping. I’ve also recently noticed in pictures I have a yellow pigmentation around my eyes. When I researched that – hypothyroid again. Through my research I also found that birth control affects the levels sometimes in THS tests. So with this new-found knowledge and list of symptoms I requested a new THS, a free T3 & T4 tests. A week later I find that all my levels came back normal. Wow. What’s a girl to do with all these symptoms? It’s also my understanding that once you’re diagnosed, you can’t cure hypothyroid. Please, I need some advice. Thank you for your time.

    • ANSWER:
      “A week later I find that all my levels came back normal. ” Dont count on it!!!!

      Some info: TSH ‘norm’ should be .3 – 3 (w/ most feeling best at < 2) but, for diagnosis, would not matter if ANTIBODIES are present. Indicative of Hashimoto’s Autoimmune Thyroiditis (cycles between hyper & hypo at start)…main cause of HypOthyroid & is worse (...OR Graves Disease - HypERthyroid). You most likely will have to get another doctor and yes, you do stay on the meds for life. WARNING: Doctors seem not to want to find/treat thyroid disease. You may have to go to more than one doctor before you get the right tests, interpretation, and treatment. Best wishes. Ck these: God bless

    Heart Problem or Something or just Anxiety?
    so ill give you a little backstory im a male 23 years old abit overweight, so it all started about 2 months ago i was at my friends house we were playing a card game (magic the gathering) it had been quite stressful day as i just came back from a tournament from playing that game and i just wanted to play some casual games with my friend so about 8 games in just starting the 9th i smelt somethin like toast and like cofee cooking i immediatly stood up and was like you smell that and he said what i said it smells like toast and hes like no then all of a sudden my forehead felt like it was being squeezed and my chest as well and my heart was just racing i told my buddy to call an ambulance right away i thought i was having a heart attack. the squeezing in the chest stopped after about 5 seconds and the forehead as well heart still pumping than the squeezing came back in the forehead for about another 5 seconds and went away i went outside and laid on the grass waiting for help the firetruck showed up and they gave me oxygen and asked me what was happening they checked my pulse and blood pressure both were high so the paramedics came and they did the same.
    They took me to the hospital and they checked me out on the ecg and did blood work, ecg was normal the blood work came back said that one of the thyroid hormone thing was abit high and i had a abnormal high white blood cell count. they also did an ultrasoud of the heart and found nothing unusual so they released me about 5 hours later. so i made a appointment with GP and talked about the results from the blood test and he got me to get another blood test for the thyroid so i did and i didnt hear anything back from it so i assume it was normal. so about a month goes by and im playin a computer game than all of a sudden i smelt like someone was smoking near me but no one smokes in the house so i looked out my window and i didnt see anything and than it happened again my heart began to race and squeezing in my forehead about the same time as before but less intense so i got my dad to drive me to the hospital since it was late at night i got admitted and they did another ecg blood work both came back fine also did a chest xray and they didnt find anything abnormal so they released me and told me that it could have been acid reflux or a muscle spasm that could have caused the pressure. so i was relived.

    so a couple days ago im at work its nearing the end of the day i just want to go home lol and i am building a mantle for our display area and then all of a sudden i felt hot and heart was racing i didnt pay much attention since it coudl have been just the fireplaces that we have in the showroom on that was making it hot but than i began to worry i went to the bathroom and put water on my face treid to calm myself down by breathing deeply didnt seem to work so i went back to work than it felt like it was getting worse so i went into the office were people were just incase something did happen i wasnt alone and then all of a sudden it happens again so we call the paramedics and they come get me just like last time i had ecg and blood work ecg came back normal with (sinus tachyardia) and the bloodwork was okay blood sugar fine. elevated levels of creatine, and a little low potassium. so they set me up with a cardiologist and got an appointment he looked at the records did some tests everything looked fine he sent me to get more blood tests and gave me a holter monitor for 24 hours which im waiting for the results he also set me up with a neurologist to do a eeg on my brain see if there is any problems there. i got the bloodtests done for serum electrolites, and tsh and if its abnormal test free t4 also fasted for 10 hours for diabetes check just to be safe. i also have a 24 urine test i still have to do and a aldosterone / Renin ratio test that i need to get an appointment for. now i just been obsessing with looking up symptoms on the internet and that just seems to make it worse. i should also add i have a resting heart rate of 84-90 and last i saw for blood pressure was at the hospital at the last visit was 139/90, i also try to exercise for 30 mins 5 days a week. so yeah i just want some input. thanks a bunch

    • ANSWER:
      anxiety, over working and olfactory hallucinations which is encouraged by the mild thyrotoxicosis, after the cardiologists final opinion you need a thorough counselling by a clinical psychologist.

    Thyroid blood tests – what do they mean?
    Have been hyperthyroid (Grave’s) for two years. Been on various different dosages of carbimazole – ranging from 5 – 40mg per day. Have also had a few breaks from Carbimazole. I am presently on 20mg daily.

    My blood teats are confusing me and no one has told me what they mean this time – I see my GP in two weeks – he’s good at explainig them – but can’t wait until then.

    March 1st 2008
    Free T4 = 5
    Free T3 = 1.2
    TSH = not detected

    Previous January 28 2008
    Free T4 =14
    Free T3 = 2.3
    TSH not detected.

    Am I still hyperthyroid?
    Am I under control?
    OR am I hypothyroid.

    Any help would be greatly appreciated – I have muscle cramps, fatigue and have put 14lb of weight on in 4 weeks!!! Feeling dreadful. Help Please. Thanks. Ps TSH has always been not detected!!

    • ANSWER:
      Well your TSH is still none detected, which to me would seem like you still have a hyperthryroid. What kind of medication did they put you on?
      It might not be your thyroid, it could even be your pituitary.
      The pituitary is what makes TSH, so if you don’t have that at all, I would think that is the problem.

      Anyways, I wish I could be more of help, I listed some really good links at the bottom, I think they will help you out!

    Thyroid peroxidase level?

    I went in for thyroid screening blood test and my results are:

    T4 free – 1.20
    TSH – 3.083
    Thyroid peroxidase antibody <10 Are these in normal range ? I tried to find out more about Thyroid peroxidase antibody levels (range) but couldn't find more. if you have any more insight into this please share. I really appreciate it. TIA!! Thank you so much for the answer.

    • ANSWER:
      In some people, their immune system attacks their thyroid and causes it to become underactive. This can happen when the immune system produces ‘thyroid peroxidase antibodies’ – antibodies that attack the thyroid. If someone tests positive for these antibodies, it doesn’t mean they will definitely get thyroid disease, but it makes it more likely. However it looks like you do not have any of these antibodies (<10 means they were below the lowest level that can be detected), so this is good - makes it less likely you will get an underactive thyroid. I'm not sure if the T4 is in the normal range because I would need to see the 'reference range' that should be given with the result. But the TSH is normal, and that is the best test to see if your thyroid is working. So nothing to worry about!

    Endocrine case study   The Case of the Sweaty Salesman?
    Endocrine case study
    The Case of the Sweaty Salesman

    Chief Complaint: In a routine physical exam Michael, a thirty year old salesman complains of excessive sweating, intolerance to heat, irritability, shortened attention span, difficulty in sleeping, weight loss with increased appetite.   He does not smoke, practices safe sex, has no family history of cardiovascular disease. He has a family history for autoimmune diseases. His father suffers from idiopathic thrombocytopenia, his mother has been diagnosed with rheumatoid arthritis and his oldest sister was recently diagnosed with systemic lupus erythematosus.

    Physical findings: (1) 15 lb weight loss since last physical; (2) tachycardia with slight hyperthension; (3) protruding eyeballs (exothalmic); (3) some degree of alopecia and palmar erythema; (4) palpitation of the neck revealed the presence of goiter.

    Based on the physical findings his doctor did some blood tests and sent him to an endocrinologist. The endocrinologist diagnosed _____________ , and suggested several treatment options. These included treatment with chemicals (propylthiouracil and methimazole) that decrease the production of thyroid hormones by the thyroid gland, or radioisotopic destruction of the thyroid gland by the use of 131I, or surgical removal of the thyroid gland. After considering all the options, especially the possible effects of radiation on sperm development, Michael chose surgery. Following successful surgery, Michael was prescribed synthetic thyroid hormone to ensure that his body was receiving adequate thyroid hormone and told to return within 2 months for a follow-up evaluation of circulating thyroid hormone concentrations. He was also cautioned to carefully monitor his calcium intake.



    Blood test results:

    • Free T4: 20  mcg/dL (normal range: 4.8 to 10.4 ug/dl).
    • TSH: 1.5 mIU/L (normal range: 0.3 – 3.0 mIU/L)
    • Calcium: 15 mg/dL (normal range: 8.5 – 10.2 mg/dL)
    • Positive for thyroid autoantibodies.




    This is the question please help


    1. What is your diagnosis?
    2. Define the bold terms in the text.  
    3. Why is the T4 levels elevated?  
    4. Thyroid hormones exert their effects on cells in a manner similar to steroid hormones; describe the mechanism of action of thyroid hormones.
    5. Why would an imbalance in thyroid hormones have such widespread effects on the body?  
    6. Why was goiter observed in Michael’s case?  
    7. Why would calcium homeostasis be impaired in response to removal of the thyroid gland?
    8. Why is 131[I] used to specifically destroy the thyroid gland and have minimal effects on other cells and tissues in the body?  
    9. Given that Michael and his wife may want to have more children, why was 131[I]  treatment ruled out

    What does this growth hormone test mean ?
    i’m almost 15 years old and 160cm you might think it’s good height but the problem my body haven’t grown or changed for 3 years so doctors advised me to make lots of examination on blood structure like magnesium,calcium ,TSH, Free T3 , Free T4 and all were normal
    but i made X-ray on my wrist and knee and doctors told me that spaces between bones are almost closed and won’t grow again!!
    the only thing wasn’t normal my GH test the result was

    Ref . Range
    Growth Hormone: 0.2 ng/ml up to 7.0
    Due to low levels and pulsatile secretion of hGH, provocative tests are recommended for
    evaluating GH deficiency.

    • ANSWER:
      Well, if the growth plates are closed, then nothing else matters, you wont’ grow significantly more.

      But in general what the rest means is that growth hormone tends to get released multiple times a day in pulses. The releases are anywhere from 1-2 hours long, and happen every 3-6 hours. So depending on what time the test was done, it may have just been at a low point. By provocative test, they mean giving you a drug that causes a gh pulse then immediately measuring.

    Hyperthyroid, Graves? Hashimoto’s? test results…?
    I have been having symptoms of Hypo and Hyper for years without knowing it. I got some tests done but I am in a foreign country so hard to understand the doctors. 1st test = Free T3, 22.58 (range 2 – 4.9) Free T4, 3.91 (range 0.7 – 1.7) Also goiter measures on both sides roughly 70mm x 35mm. This doctor gave me anti thyroid drug and beta blockers. Took them for 2 months and then stopped because I found info on how it damages you liver. Stopped the medication for 2 weeks to get them out of my system a bit and then went to doc’s again and got new tests as follows: TSH, 0.006 (Range 0.27 – 4.20) / Free T4, 1.83 (range 0.71 – 1.85) / Free T3, 8.47 (range 1.80 – 4.60) / Anti-TPO, 1773.00 (Range 0.00 – 34.00) I had loads of results from blood work but these are the ones that are funny looking: RDW-SD, 35.5 (range 37.00 – 54.00) / RDW-CV, 11.4 (range 11.50 – 14.50). This doc wanted me to go back on previous meds followed by operation to cut out the Thyroid or have RAI. Firstly, I don’t understand what my results show. Do I have Graves like last doc suggests? or Hashimoto’s because of the high anti-TPO? I don’t understand. Secondly, is there any way to manage this through naturel medicines I would need to get the TPO down and sort out my thyroid Free T’s and get my TSH up!… What should I do? I have very severe symptoms and need some help. As I say, I am not in UK, ı am in Turkey and so very hard to understand doctors. Thanks for any advises:) x
    Thanks for your reply Lisa,

    But what about the anti-TPO??? I thought maybe hashi’s because the TPO will be attacking my thyroid?

    • ANSWER:
      You probably have Grave’s disease, but there is no way to know until you have the test for Grave’s. You need a TSI test. People with graves also have high TPO, so it’s not an indication of anything really.

      You should definitely have been on the anti-thyroid drugs. You should never have gone off of them, and you need to get back on them.

      And if you have Grave’s disease, never, never treat your TSH level. It’s not relevant anymore. And it’s not a thyroid hormone. It doesn’t affect how you feel. Ignore it. You need to concentrate on getting euthyroid (normal free T3 and free T4), and getting rid of your symptoms. By treating TSH levels in Grave’s disease, you will be rendered extremely hypOthyroid, and very very sick. TSH levels stay supressed sometimes for YEARS when you have Grave’s. Ignore it. Get back on the anti-thyroid drugs, and get your thyroid hormone levels (free T3 and free T4) down, and get your symptoms resolved.

    My husband had his hormones tested on 3/31/10 by blood test. Here are the results: (No hair loss at this point, full thick head of hair, no male pattern baldness in family, no history of hair problems)
    testosterone, serum – 163 (low)
    testosterone % – 29 (normal)
    testost, F+W – 47.3 (normal)

    TSH .461

    Estradiol, Sensitive – 10 (normal)
    DHEA sulfate – 19.4 (Low)
    Progesterone – less than 0.1 (Low)
    Cortisol – PM – 2.6 (normal)
    Vit. D – 21.1 (Low)
    PSA – .7

    On 4/4/10 he went to the emergency room with symptoms of H1N1 and was told he had bronchitis, so the next week he stayed in bed and by 4/10/10 he was in critical condition and on a ventalator for 12 days almost dying. In the hosptial the doctors gave him lots of different antibotics, but refused to give him the Tamaflu until the CDC called to confirm his diagnosis of H1N1, then he began to improve.

    When he got out of the hospital, the APN who did his bloodwork for HRT Therapy said his hormones were at extremely low dosages and that he needed to come in right away for treatment.

    She knew of this condition with H1N1 and started him with 1 shot of 250 cc of testosterone cynpionate and 7 days later put him on a testosterone cream dosage of 100 mg per day. He took this dosage for approximately 3 weeks and then began to get a few pimples so he reduced his cream dosage to 75 mg for the next two weeks. He went back to the APN for follow up blood work and at this time had no problems with the therapy or major side effects. At the office visit, she gave him another 200 cc of testosterone cynpionate – he continued with the 75 mg daily dosage of the testostone cream. About 12 days after this his hair began falling out or thinning rapidly at the sides of his head. He called the APN and asked for help, but she refused to call him back. He continued with the daily dosage of 75 mg of testostone cream for another week at which time he just stopped the cream completely. Two weeks later he went for repeat blood work, here are the results: (At this point, his hair is very thin at sides of head and back of head, but not the crown or top)

    On 7/2/10 the blood results are as follows:

    Comp. Metabolic Panel – all in normal range except glucose 115(high)

    Testosterone, serum – 139 (Low)
    Testosterone % – 20.5
    Testosterone F+W – 28.5 (Low)
    Dihydrotestosterone – 18
    TSH – .916
    T4, Free, Direct – 1.07
    Estradiol, Sensitive – 16
    DHEA sulfate – 15.4 (Low)
    Calcium, Ionized, serum – 4.8
    Triodothyronine, free, serum – 2.8
    Vit. D – 29.7

    Today, my husbands hair is still falling out, more thinning at sides, back, top and now starting to thin at the crown.

    He has been to see an Internist, Dermatologist, asked the APN who gave him the hormones and nobody wants to comment on what is causing his hairloss.

    Please only individuals with specific knowledge about this topic provide him with any information you may have.

    I would like to know if the amount of testosterone that he was given is a high amount? If this would cause hair loss? Will it grow back? When will it stop falling out? Could he have another problem?

    How do I read my Thyroid Levels? .. Something is seriously wrong, what could it be?
    I went to the doctor in Sept. to have a thyroid test done. I have all the symptoms, yet they say my numbers are normal. I know that they recently changed the normal ranges to 0.3-3.04, and I was wondering how my numbers fit into that category, I’m not sure how to read them

    T3 – 0.98
    TSH – 0.925
    T4 6.1
    T4 free- 0.75

    I’m not sure if I do have a thyroid problem, but here are my symptoms:
    severe fatigue, weight gain, difficulty losing weight, low motivation and ambition, cold intolerance, headaches, irritability, anxiety, hair loss, depression, decreased memory and concentration, unhealthy nails, constipation, acne, digestive problems, hypoglycemic symptoms (low blood sugar), ect.
    I have been treated for candida, balancing gut flora, & have also been on an anti-inflammatory diet. I’ve had tons of blood tests and they always come out fine.

    I thought maybe if I put this out there it may be familiar to someone. Any help would be great, I’m getting too tired to fight this. Thanks a ton-

    • ANSWER:
      Your free t4 is on the low side. You didn’t have a free T3, so you can’t tell about that. Your T3 total looks a little bit on the low side too. TSH is a lousy test for diagnosis because TSH fluculates throughout the day. So if you tested in the afternoon, it may stop you from getting a diagnosis. I suggest you retest in the morning and ask for a Free T4, Free T3, and an antibody test. I have put a few links below for you to read up on. The more you know, the better chance you will get a diagnosis.

    I have hyperthyrodism. Has anyone been treated/cured for it and gained weight.?
    Hello. I am a 29 year old guy and always wanted to gain weight. I ate and did weight training but could not gain any substantial weight. I had a blood test done and found out I have hyperthyroidism. I only weigh 65kgs.
    My results came as:

    Free T4 24.6
    TSH 0.61
    Free T3 7.3

    Is there anyone that was skinny and was treated for hyperthyrodism and then gained weight? What treatment you used.
    I am currently on pills (carbumazole tablets – neo-mercazole) but have to book for an ultrasound and dye radiation. Is it easy to treat/cure?


    • ANSWER:
      Your hyperthyroidism will have increased your metabolic rate, so there is a strong likelihood that you will gain some when treatment returns you to the euthyroid state. The condition is easy to ‘cure’ with radio iodine, but most patients are left underactive and require lifelong thyroid hormone replacement with levothyroxine.

    Could someone please explain these tests to me.?
    I’m getting my blood drawn and tested for: Basic Metabolic (CHEM 8), CBC, Platelet, and Diff, Sed Rate, Iron & TIBC, T4,Free, TSH, and under additional tests it says :Prolactin.
    I will say, I don’t understand what they are (my doctor didn’t tell me what they mean/what the results could be).
    I’m really nervous, just because I’ve never had blood drawn before.
    Also does anyone know, about how much/how many vials they may take?
    (My mom has had her blood drawn before, and she told me about the vials and stuff. I’m still more nervous than ever).

    • ANSWER:
      They will take a vial or is not painful. They will check your electrolytes, all levels of functioning fluids, plus your white and red blood cell count, your thyroid…. Just relax it is standard and hopefully precautionary. Good luck. Let me know how it went. God bless
