About ACTH Test | Adrenocorticotropic Hormone in Downey
ACTH is produced by the pituitary gland and acts on the adrenal glands as a directive to release cortisol.
The pituitary releases ACTH in pulses, and those pulses follow a daily rhythm, generally peaking in the early morning and falling later in the day. A single measurement therefore captures one point in a moving cycle rather than a fixed baseline.
Cortisol feeds back to the pituitary and hypothalamus, so the system regulates itself. When cortisol is low, ACTH typically rises to stimulate the adrenal glands; when cortisol is high, ACTH typically falls. This inverse relationship is what makes paired testing useful.
Results are interpreted in relation to cortisol, medication history, and symptoms rather than as an isolated number. A clinician uses the pattern to distinguish among adrenal, pituitary, and other causes of abnormal cortisol signaling.
