High TSH but normal T3 T4

[shuklasatish05]

Hello everyone, I am 27 year old male. My T3 and T4 is 115.3 and 5.78 respectively but TSH is 6.01. What does it means?? Does I need clinical treatment or something else. Plz help.

More than likely your Free T3 and Free T4 are low. Get someone to check these levels. These are better indicators of your thyroid function. Also have them run an anti-TPO antigen. High levels indicate Hashimoto's thyroiditis aka autoimmune-thyroiditis. Even when a TSH level may fall in the so called normal range, one can frequently find that the Free T3 and/or the Free T4 can still be low.

These two are thyroid hormones, where as the TSH is not. That is a pituitary hormone which stimulates the thyroid to produce more thyroid hormones.

Where thyroid is concerned, there's no such thing as 'normal'. What you mean is, your results are 'in range'. But, just being 'in range' is not good enough. They need to be in the right place in the range. However, it's impossible to say anything about yours because you haven't given us the ranges. Ranges vary from lab to lab, depending on what machine they use, so always give the ranges, please.

Having said that, your TSH is too high for good health. Do you have symptoms? Is this the first time you've had a thyroid test? Or have you had other's with a high TSH? If it's the first time, I would suggest you wait six months and get tested again. TSH can be affected by other things in the body and doesn't necessarily mean a problem with the thyroid. It could go down again.

However, if you've had a string of tests with a high TSH, you are indeed hypo and should be treated. As vtm7 said, ask for your antibodies to be tested. And also your vit D, vit B12, folate and ferritin. If these are low, they can cause thyroid-like problems.

T3 normal range 84.61 to 201.7

T4 normal range 3.2 to 12.7

Tsh normal range 0.27 to5.5

That T3 is a TT3, isn't it? Not an FT3. It doesn't give you any useful information. But your FT4 is a bit on the low side. However your TSH is saying, in that test, that you haven't got enough thyroid hormone in your blood to satisfy the pituitary.

I repeat what I said above, if that's the first time you've had a test with a high TSH, you should wait six months and retest, to make sure it isn't a fluke. But, if it's the latest in a series of high TSHs then you need thyroid hormone replacement.

Your T3 and T4 appear to be too low in their ranges for you. We are all different, and we each have points in the ranges that are appropriate for us personally.

Well obviously your TSH is too high and your FT3 and FT4 levels are low in their ranges. Definitely get more tests as above - vitamins, iron panel etc.

You need to have the full panel before anyone here can make a reasonable judgement. The full panel to evaluate for primary hypothyroidism is TSH/FT3/FT4/rT3/TPOAb/TGAb. Post the results here with units, and the range the lab provides for each test. The "frees" (FT3 & FT4) are preferred because they tell you, regardless of how much TBG (Thyroid Binding Globulin) you have, how much of the active and storage thyroid hormones are actually available in the bloodstream for use.

Are you on nutritional supplements, and do you have a very clean diet? If not, it will be helpful to know where some of your nutritionals are, e.g. B vitamins, D3, trace minerals.

Good advice above, but how do you feel? What took you to the docs in the first place? If you have no symptoms I would leave well alone, if it ain't broke, don't fix it. It is awfully difficult to get hormones into balance via pills, if you have no symptoms with a TSH of 5 (even though that does say hypothyroidism) I would still not act until you have a symptom.

I just gone for normal health check up and I come to know about it. I dont have any symptoms of any kind of illness.
