ACTH (Cosyntropin)

ACTH (adrenocorticotropic hormone), often given as a synthetic form called cosyntropin, is a medication used to assess how well the adrenal glands respond. When administered, it stimulates the adrenal glands to produce cortisol, a vital hormone that helps manage stress, inflammation, and blood sugar levels. Doctors use cosyntropin tests to diagnose conditions like adrenal insufficiency, where the glands don't produce enough cortisol. The test provides insight into adrenal function and helps guide treatment decisions, ensuring the body maintains balance and responds properly to stress.
