17 – KETOSTEROIDS, 24–HOUR URINE
17-ketosteroids (17-KS) are derived from adrenal cortex and testes and are excreted in the urine. These are metabolites of adrenal and gonadal androgenic steroids. In men, 60-70% & in women nearly 100% of these are produced in the adrenal cortex. They are useful in evaluating gonadal and adrenal disorders.
