LP17184-0   17-Hydroxypregnenolone
17-Hydroxypregnenolone (also 17-OH-pregnenolone and 17-alpha-hydroxypregnenolone), is a C21 steroid that is obtained by hydroxylation of pregnenolone at the C17-alpha position. This step is performed by the mitochondrial cytochrome P450 enzyme 17-hydroxylase (CYP17A1) that is present in the adrenal and gonads. Peak levels are reached in humans at the end of puberty and then decline. High levels are also achieved during pregnancy.
Measurements of 17-OH-pregnenolone are useful in the diagnosis of certain forms of congenital adrenal hyperplasia. In patients with congenital adrenal hyperplasia due to 3 beta-hydroxysteroid dehydrogenase deficiency 17-OH-pregnenolone is increased, while in patients with congenital adrenal hyperplasia due to 17 alpha-hydroxylase deficiency levels are low to absent. Measurements of 17-OH-pregnenolone are useful in the diagnosis of certain forms of congenital adrenal hyperplasia. In patients with congenital adrenal hyperplasia due to 3 beta-hydroxysteroid dehydrogenase deficiency 17-OH-pregnenolone is increased, while in patients with congenital adrenal hyperplasia due to 17 alpha-hydroxylase deficiency levels are low to absent.

LP17184-0   17-Hydroxypregnenolone
17-Hydroxypregnenolone, also known as 17-OH-PG, is a steroid hormone that is derived from cholesterol. 17-OH-PG is involved in the synthesis of cortisol, aldosterone and androstenedione in the adrenal glands. 17-OH-PG levels are measured to screen for congenital adrenal hyperplasia (CAH), a group of inherited disorders of the adrenal gland. High levels of 17-OH-PG in the blood indicate cortisol and aldosterone are not being produced in normal levels. PMID: 20077078 Source: Regenstrief LOINC
