Order ACTH Test | Adrenocorticotropic HormoneThe ACTH test measures the amount of adrenocorticotropic hormone in a blood sample. This hormone, produced by the pituitary gland, signals the adrenal glands to release cortisol. Because ACTH and cortisol work together in a feedback loop, measuring ACTH helps clarify how that loop is functioning.
About ACTH Test | Adrenocorticotropic Hormone in Niles
Adrenocorticotropic hormone is a regulatory signal, not a direct measure of adrenal output.
The pituitary gland secretes ACTH in pulses, and its release is governed by the hypothalamus and by circulating cortisol levels. When cortisol is low, ACTH typically rises; when cortisol is high, ACTH typically falls.
A blood sample is collected and the ACTH level is measured in a laboratory. Because the hormone is released in bursts and is fragile outside the body, sample handling and timing matter, and the lab's collection instructions should be followed closely.
Results are usually interpreted alongside a cortisol measurement. The relationship between the two values can help distinguish patterns that originate in the pituitary, the adrenal glands, or elsewhere, though a single result rarely stands alone as a diagnosis.
