Currently, guidelines suggest using TT to diagnose androgen deficiency and to reserve cFT only for men with borderline TT. Objective: Our objective was to investigate if either low cFT or low TT is more strongly … Free Androgen Index (FAI) is a ratio used to determine abnormal androgen status in humans. The ratio is the total testosterone level divided by the sex hormone binding globulin (SHBG) level, and then multiplying by a constant, usually 100. The concentrations of testosterone and SHBG are normally measured in nanomols per liter. FAI has no unit. The majority of testosterone in the blood does not exist as the free molecule.
