ACTH Test in Oklahoma — Request Locally

An ACTH test measures the amount of adrenocorticotropic hormone in your blood. This hormone, made by the pituitary gland, tells your adrenal glands to produce cortisol. The test helps evaluate conditions like adrenal insufficiency, Cushing's syndrome, or pituitary disorders.

What it measures

ACTH — The level of adrenocorticotropic hormone in your blood.
Cortisol (often paired) — A hormone from the adrenal glands that ACTH controls; sometimes checked at the same time.

Who it is for

Doctors order this test when they suspect a hormone imbalance, such as too much or too little cortisol, or to monitor a known pituitary or adrenal condition.

Preparation

Your doctor may ask you to fast overnight or to have the test at a specific time, often in the early morning. Sometimes no special preparation is needed.

Results and what they mean

Results are reported as a number with a reference range. Your clinician will interpret the result along with your symptoms and other tests. This is general information, not medical advice; only your healthcare provider can diagnose or treat any condition.
