FREE ANDROGEN INDEX (FAI)

The Free Androgen Index (FAI) is a laboratory calculation used to estimate the amount of biologically active (free) testosterone by relating total testosterone to Sex Hormone Binding Globulin (SHBG). It is derived from a standard blood sample and provides a simple, clinically useful indicator of androgen status when direct free testosterone assays are unavailable or complementary. At-home sample collection in Dubai with UAE-accredited laboratory analysis makes testing convenient while maintaining clinical reliability.

FAI is important for evaluating symptoms of low or excessive androgens in men—such as low libido, erectile dysfunction, fatigue, loss of muscle mass, or infertility—and for monitoring response to testosterone replacement therapy. Results support physician decisions on further endocrine evaluation, treatment adjustments, or fertility investigations; always review results with a qualified healthcare professional in the UAE before changing medications or therapy.
