What are the normal range for TSH, T3 and T4 levels in human body?

I am looking for the normal range for thyroid test.


  • TSH or Thyroid Stimulating Hormone, the normal range lie here:

    TSH :  0.4 to 4.0 mIU/L.

    If you're already being treated for a thyroid disorder, 

    normal range is 0.5 - 3.0 mIU/L.

    T3 : 100 - 200 (ng/dL)

    T4 : 5.0 to 12.0 (μg/dL).

     Results for children vary based on age.
