Order ACTH Test | Adrenocorticotropic HormoneThe ACTH test measures the amount of adrenocorticotropic hormone circulating in the bloodstream. Because this hormone is central to the body's stress response and to the regulation of cortisol, its measurement often serves as a starting point when the adrenal or pituitary systems need closer examination.
About ACTH Test | Adrenocorticotropic Hormone in Fallbrook
ACTH is a signaling hormone, not a direct measure of adrenal output.
Adrenocorticotropic hormone is produced by the pituitary gland, a small structure at the base of the brain. Its primary role is to prompt the adrenal glands, which sit above the kidneys, to release cortisol. Cortisol in turn influences blood sugar, blood pressure, immune activity, and the body's response to physical stress.
Because ACTH and cortisol operate in a feedback loop, the two are usually interpreted together. When cortisol levels fall, the pituitary typically increases ACTH production; when cortisol levels rise, ACTH production tends to fall. A result that breaks this expected pattern can point toward a problem in the pituitary, the adrenal glands, or the signaling between them.
The test itself requires only a small blood sample. Timing can matter, since ACTH levels shift throughout the day, so the collecting lab may specify when the draw should occur. Certain medications, stress, and sleep patterns can also influence results, which is why the ordering clinician reviews the number alongside the broader clinical picture rather than in isolation.
