17-Hydroxyprogesterone is a C-21 steroid hormone produced during the synthesis of glucocorticoids and sex steroids. As a hormone, 17-OHP also interacts with the progesterone receptor.
Measurements of 17-OHP levels are useful in the evaluation of patients with suspected congenital adrenal hyperplasia (CAH) as the typical enzymes that are defective, namely 21-hydroxylase and 11β-hydroxylase, lead to a build-up of 17-OHP.
In contrast, the rare patient with 17α-hydroxylase deficiency will have very low or undetectable levels of 17-OHP. 17-OHP levels can also be used to measure contribution of progestational activity of the corpus luteum during pregnancy as progesterone but not 17-OHP is also contributed by the placenta.
The application of 17-OHP has been shown to be useful to delay premature labor in pregnancy.

May 22, 2019 Advisory:
17OHP products (5225-300 and 5275-300) have been improved with ready-to-use
Enzyme and Tracer Reagent. Steroid Conjugate Buffer will no longer be
included in the products, therefore the mixing step is eliminated.
