Thyroid levels

[josephabishek]

My thyroid values are as follows
Free t3: 3.21 Pg/ml
Free t4: 1.42 ng/dl
Tsh : 4.21uIU/ml
Is this normal??

Thank you very much.
I'm going to follow test's you suggested
and take needed measures.
Hope everything gets to normal

Your Free T4 is at 64% of its range, which is adequate for most people.  Your Free T3 is at 50% of its range, which is not bad, although everyone is different and some need FT3 to be higher.  TSH is a pituitary hormone that is affected by some many things that at best it is only an indicator, to be considered along with more important indicators such as symptoms and FT4 and FT3.  That said, your TSH is a bit higher than would be expected and it would be good to follow up with a test for the antibodies of Hashimoto's Thyroiditis.  Those tests are TPO ab and TG ab (if TPO ab is negative).  Those tests will reveal if you are in the early stages of Hashi's.

Also, serum thyroid levels sometimes do not accurately reflect tissue thyroid levels.  Symptoms result from inadequate tissue thyroid effects, which are a result of tissue thyroid hormone levels and a few other variables.  It has been reported that the best measure of tissue thyroid levels is the ratio of Free T3 to Reverse T3, taken from the same blood draw.  So it might be a good idea to ask to be tested for Reverse T3 and Free T3 again.  Along with that it would be good to test for other variables that affect tissue thyroid effects, such as Vitamin D, and a morning serum cortisol test.  I would also ask for a B12 test since a deficiency can cause symptoms as well.

So the answer to your question is no things are not normal for you, otherwise you would not have those symptoms.  Your thyroid related test results so far do not clearly stand out as being hypothyroid, so you need to get additional tests done to be sure of the cause of your symptoms.

Please post the reference ranges shown on the lab report for those results.  Results always should be compared to the ranges from the same lab.  

More importantly, what symptoms do you have?
