A new method for free testosterone assay: clinical evaluation.

The Authors propose a new direct method for the determination of free Testosterone (F.Te). Our study was made following this method: 1) on a control group composed of 12 healthy men and 21 healthy women, and 2) on a group of 29 patients suffering from Polycystic Ovary Syndrome (PCOS) with clinical signs of hyperandrogenism. This pathological group presented acne and hirsutism in 95% of the cases. The Authors demonstrate how the determination of F.Te permits a 93.1% correct endocrinological diagnosis of hyperandrogenism.
