17-Hydroxyprogesterone Unit Converter
17-Hydroxyprogesterone (17-OHP) is a steroid hormone precursor produced primarily in the adrenal glands, gonads, and placenta. It plays a key role in the biosynthesis of vital hormones such as cortisol and androgens by acting as an intermediate in the steroidogenic pathway.
Under normal physiology, 17-OHP is converted downstream by enzyme systems — notably 21-hydroxylase and 11-beta-hydroxylase. Elevated levels may signal impairment of these systems (e.g., in congenital adrenal hyperplasia). This unit converter allows lab professionals and clinicians to switch seamlessly between common reporting units such as pg/mL, ng/mL, ng/dL, and nmol/L.

Clinical Context
17-Hydroxyprogesterone (17-OHP) testing is commonly performed to assess adrenal function and to screen for congenital adrenal hyperplasia (CAH). Under normal physiology, 17-OHP serves as an intermediate in the cortisol synthesis pathway. Typical adult serum levels range from 0.2 – 1.0 ng/mL, though reference intervals vary by laboratory and assay method. Persistent elevation may indicate enzyme deficiencies such as 21-hydroxylase deficiency. Accurate unit conversion allows consistent interpretation of results across different reporting standards and laboratories.
