Assesses 17-hydroxyprogesterone levels before and after ACTH stimulation using mass spectrometry. Key test for diagnosing 21-hydroxylase deficiency in congenital adrenal hyperplasia.
Serum or Plasma
1 mL (each specimen)
Red-top tube, gel-barrier tube, or lavender-top (EDTA) tube
No special preparation is required for this test. You may eat, drink, and take your medications as normal, unless instructed otherwise by your healthcare provider.
Draw blood for baseline 17OH progesterone. Inject cosyntropin 250 ug I.M. or I.V. (if I.V., dilute cosyntropin in 2-5 mL of sterile saline and inject over 2 minutes). Draw blood for stimulated 17OH progesterone 60 minutes after.
