Free Thyroxine Index (FTI) Calculator
This calculator estimates the value of the free thyroxine index (FTI), which is a measure of the amount of free thyroxine in the blood. The FTI is calculated by dividing the total thyroxine level by the thyroxine-binding index (TBI) or T-uptake determination.
The normal range for the FTI is typically between 1.2 - 4.9 Units, though specific reference ranges may vary depending on the laboratory and population being tested.
