17-OH Progesterone/Creatinine Ratio, Random Urine
17-Hydroxyprogesterone (17-OHP) in urine is greatly elevated in patients with polycystic ovarian disease and in patients with idiopathic hirsutism. Wong and coworkers showed that measurement of 17-OHP in 24-hour urine produced results that may be useful for monitoring glucocorticoid and mineralocorticoid therapy in patients with congenital adrenal hyperplasia (CAH).1 Other studies have shown that 17-OHP in 24-hour urine correlated well with serum 17-OHP and suggested that the urine measurement of 17-OHP may be a reliable alternative to serum 17-OHP measurement for monitoring of CAH therapy.
