Normal Levels of  T3  T4   TSH  ?

[cat4720]

TSH 0.5-5.0, T3 2.8 - 5.2 and T4 0.8 - 2.2. However I believe this can vary from clinic to clinic. This is what my clinic states as standard range.

The level for TSH is the US should be 0.3-3.0; however many labs/doctors don't use that, and if you are in a different country, it may be different.  

Reference ranges for Free T3 and Free T4 vary from country to country and lab to lab, so must always come from your own lab report.  You ARE getting FREE T3 and FREE T4 aren't you?  Not total?

Depends on the person. Depends on the country you live in, meaning that 'normal' levels vary from pathology lab to pathology lab even in different countries.  Depends if you know your own levels when you feel ok. Not an easy answered question.
