Urinary/serum hCG (human chorionic gonadotropin) and urinary biotin concentrations in both treatment groups before, during, and after hCG intervention using standard immunoassay methods 2. To monitor hCG in both treatment groups before and after diafiltration of urine samples prior to analysis 3. To compare urinary and serum detectability (detection window, sensitivity) of hCG abuse in the hCG-only group compared to the hCG + biotin group
