Order ACTH Test | Adrenocorticotropic HormoneThe ACTH test measures the amount of adrenocorticotropic hormone in the bloodstream. ACTH is produced by the pituitary gland and acts as a signal to the adrenal glands, prompting them to release cortisol and other steroid hormones. Because this hormone sits at the center of the body's stress-response system, its level can offer useful clues about how the pituitary and adrenal glands are communicating.
About ACTH Test | Adrenocorticotropic Hormone in Oceanside
ACTH is a regulatory hormone, not a direct measure of adrenal output.
Adrenocorticotropic hormone is a polypeptide secreted by the anterior pituitary gland. Its primary role is to stimulate the adrenal cortex to produce cortisol, the body's main glucocorticoid, along with androgens and aldosterone. Cortisol then feeds back to the pituitary and hypothalamus, creating a loop that keeps hormone levels within a narrow range.
When a clinician orders an ACTH test, the goal is usually to understand why cortisol levels are abnormal. A high ACTH result alongside low cortisol points toward a problem in the adrenal glands themselves, since the pituitary is working harder to compensate. A low ACTH result alongside low cortisol suggests the pituitary or hypothalamus is underactive. When cortisol is high, ACTH can help distinguish between an adrenal source and a pituitary or ectopic source.
ACTH is measured from a blood sample, and results are typically interpreted alongside a cortisol level drawn at the same time. Because ACTH is released in pulses and varies throughout the day, timing and collection conditions matter, so the lab's instructions should be followed carefully. Reference ranges differ between laboratories, and a single result is rarely diagnostic on its own.
