17-OH Pregnenolone ACTH Stimulation LabCorp

This test measures the level of 17-OH pregnenolone in your blood before and after you receive an injection of ACTH, a hormone that stimulates your adrenal glands. It helps doctors check for certain adrenal gland disorders, like congenital adrenal hyperplasia, by seeing how your adrenal glands respond to the stimulation. The test can help determine if your body is producing hormones correctly.
