17 Hydroxyprogesterone is a steroid hormone made during the synthesis of other hormones such as cortisol and oestrogen. It is produced in the adrenal glands and the reproductive organs. Levels are tested to investigate cases of congenital adrenal hyperplasia.
What might a low result mean?
Low levels of 17 Hydroxyprogesterone could indicate a rarer form of congenital adrenal hyperplasia which is due to a deficiency in the enzyme 17 hydroxylase.
What might a high result mean?
Raised levels of 17 hydroxyprogesterone could indicate the presence of an inherited disorder called congenital adrenal hyperplasia, in which individuals produce inadequate or excessive amounts of a vast range of hormones.
