21-Deoxycortisol, also known as 11β,17α-dihydroxyprogesterone or as 11β,17α-dihydroxypregn-4-ene-3,20-dione, is a naturally occurring, endogenous steroid related to cortisol (11β,17α,21-trihydroxyprogesterone) which is formed as a metabolite from 17α-hydroxyprogesterone via 11β-hydroxylase.^[1] It is a marker of congenital adrenal hyperplasia due to 21-hydroxylase deficiency.^[1] The corticosteroid activity of 21-deoxycortisol is virtually abolished relative to that of cortisol.^[2]

As 21-Deoxycortisol can be a high levels in congenital adrenal hyperplasia, and it has structural similarity to cortisol it can cross-react in immunoassays^[3]^[4], resulting in a falsely normal or high cortisol result, when the true cortisol is actually low.
