Comment: Used in the investigation of congenital adrenal hyperplasia. Increased in C-21-hydroxylase enzyme deficiency, some cases of ovarian or adrenal neoplasms, and in congenital adrenal hyperplasia. Decreased in Addison’s disease. Low levels of 17-hydroxyprogesteron lead to a decline in the levels of estrogens and androgens
