What is ACTH?
An ACTH test measures ACTH, a hormone released from the anterior pituitary gland in the brain. This test can help find the causes of hormone problems. The main function of ACTH is to regulate the steroid hormone cortisol, which is released by the adrenal cortex. Normal values 9-52 pg/ml (picigrams per milliliter). Higher than normal levels of ACTH may be due to addisions disease, adrenoleukodystrophy, congenital adrenal hyperplasia, Cushings disease, nelsons symdrome. Lower than normal levels of ACTH lead to pituatory insufficiency.
