Free Androgen Index FAI Serum Test Overview

Testosterone is a hormone synthesized by both males and females. It is responsible for organ development and various sexual functions. Sex Hormone Binding globulin [SHBG] is protein that attaches to the sex hormones and controls their utilization in the body. A free androgen index (FAI) is a ratio of testosterone to SHBG [Sex Hormone Binding Globulin] which helps in identifying excessive androgen activity in the body.

Frequently Asked Questions

FAI is used to identify excessive androgen activity and thus useful in the evaluation of mild disorders of androgen metabolism. It is also used to diagnose other hormonal disorders.

The test measures the ratio of testosterone to SHBG in the blood.

This test requires a blood sample. A tourniquet (elastic) band is placed tightly on the upper arm. The patient is then asked to make a fist. This helps in the build-up of blood filling the veins. The skin is disinfected before needle insertion and the blood sample is collected in vacutainer.

A high free androgen index value indicates that there is too much biologically active testosterone in the blood. This may indicate hormonal imbalance. Low-free androgen index indicates testosterone deficiency. Results should be further evaluated in consultation with the treating clinician.
