Order ACTH Test | Adrenocorticotropic HormoneACTH testing measures the amount of adrenocorticotropic hormone circulating in the bloodstream. Because ACTH is the pituitary signal that tells the adrenal glands to produce cortisol, its level is often interpreted alongside cortisol rather than in isolation. The result helps clarify where a hormonal problem originates: at the pituitary, at the adrenal glands, or from an external source of steroid medication.
About ACTH Test | Adrenocorticotropic Hormone in Southlake
ACTH testing is a blood test that quantifies adrenocorticotropic hormone, the pituitary hormone that drives cortisol production.
ACTH is produced in the anterior pituitary gland and released in pulses, with levels typically highest in the early morning and lowest in the evening. It travels through the bloodstream to the adrenal glands, where it stimulates the release of cortisol. This relationship forms a feedback loop: when cortisol rises, ACTH usually falls, and when cortisol drops, ACTH usually rises.
Because of that loop, ACTH is rarely meaningful on its own. A high ACTH alongside a high cortisol points toward a pituitary or ectopic source driving the adrenal glands. A low ACTH alongside a low cortisol suggests the pituitary is underactive. A low ACTH with a high cortisol suggests cortisol is coming from outside the body's normal signaling, such as steroid medication.
The test requires a small blood sample, and timing matters because ACTH fluctuates throughout the day. Results are usually interpreted together with a simultaneous cortisol measurement, and sometimes with additional testing, to build a complete picture of adrenal and pituitary function.
