ACTH stands for Adrenocorticotropic hormone, an endocrinology & diabetes abbreviation.

Pituitary hormone that stimulates the adrenal cortex to produce cortisol. Measuring ACTH with cortisol separates adrenal from pituitary causes of adrenal insufficiency and Cushing's syndrome, and synthetic ACTH (cosyntropin) is used in the standard stimulation test.

Example: Cosyntropin stimulation: cortisol 9 at 60 minutes with high ACTH, consistent with primary adrenal insufficiency.

Usage notes

Also called corticotropin. ACTH is released in pulses with a morning peak, so samples are timed. High levels in Addison's disease cause skin darkening because ACTH shares a precursor with melanocyte-stimulating hormone. Small-cell lung cancer can secrete ectopic ACTH and cause severe Cushing's syndrome.
