This model quantifies the amount of hair growth on nine areas of the body. Hair growth is rated using a scale of 0 (no terminal hair) to 4 (maximal growth) for a total score of 36.

These tests include free testosterone, total testosterone, and dehydropiandosterone sulfate (DHEAS). Women with PCOS tend to have elevated levels of free testosterone in their systems because they do not have enough sex hormone-binding globulin produced by the liver. Normally, testosterone will bin
