Frequently Asked Questions (FAQs)

Free Androgen Index (FAI) is used as a surrogate marker for androgen status and is best interpreted along with other markers of androgen status, such as free testosterone SHBG, total testosterone and gonadotropins. FAI correlates well with free testosterone in women and in men, it is affected by changes in SHBG and fluctuations in total testosterone, based on circadian rhythm. In non-obese, non-hirsute oligomenorrheic women, an elevated AI during the early follicular phase is reported to be a sensitive and specific indicator of Polycystic Ovarian Disease (PCOD).
