fT3 (free triiodothyronine)

fT3 is the active form of the thyroid hormone that acts directly in the cells and regulates metabolism. It influences heart rate, energy consumption, digestion, and many other body functions. A large portion is produced by the conversion of the hormone T4 into T3 in the liver and kidneys.

Elevated fT3 levels usually indicate hyperthyroidism, while low levels may suggest hypothyroidism or a disturbance in the conversion of T4 to T3.
