Objective: The free androgen index (FAI) is the ratio between total testosterone and sex hormone binding globulin (SHBG), and it has been proposed as a marker. FAI is increasingly used in the definitive diagnosis of patients with hyperandrogenism. Although the reference range of FAI in adult females has been identified, there are no adequate studies on the reference range for adolescent girls. We determined the diagnostic value of FAI in adolescent girls diagnosed with obesity, idiopathic hirsutism (IH) and polycystic ovary syndrome (PCOS).
