17-Hydroxyprogesterone Test
The 17-hydroxyprogesterone test measures the level of this hormone in a blood sample. Quest describes it as useful in evaluating congenital adrenal hyperplasia (CAH) and in monitoring related hormone therapy.
About this test
17-hydroxyprogesterone is a hormone that is elevated in people with congenital adrenal hyperplasia, a group of inherited, autosomal recessive conditions marked by low cortisol and high ACTH. Quest lists this test under names such as 17-OHP and OH-Progesterone, alongside 17-Alpha-Hydroxprogesterone, and all refer to this same measurement.
The result is a single concentration of 17-hydroxyprogesterone in serum, measured using chromatography/mass spectrometry from a 0.5 mL blood sample collected in a red-top tube.
Who might consider this test?
- Often working through an evaluation of congenital adrenal hyperplasia
- Tracking cortisol replacement therapy over time
- Looking into infertility or an adrenal or ovarian finding
