Free T4 (fT4) The thyroid produces two hormones: thyroxine (T4) and triiodothyronine (T3). T4 is primarily inactive. Its primary job as a "storage hormone" is to transport T3 to the proper organs in your body. T4 must be converted to T3 before your body can use it to get energy or deliver oxygen to cells.

A normal TSH level falls between 0.4 and 5.0 milliunits per liter (mU/L). Except for rare circumstances, a TSH of 10 mU/L or higher means the person is hypothyroid.
