17 alpha-hydroxyprogesterone is used in the diagnosis of congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency and for monitoring of treatment of CAH. It may also be used in the identification of heterozygotes for CAH and mild late-onset forms. Samples for diagnosis of 21-hydroxylase deficiency should not be taken within 48 hours postpartum and preferably before any steroid therapy. Premature and sick babies may show moderately increased levels of 17 alpha-hydroxyprogesterone.
