Special instructions

Have sample taken between 7am and 10am.
Adrenocorticotropic hormone or ACTH is produced by the pituitary gland. The main role of ACTH is to stimulate the production and release of the stress hormone cortisol from the adrenal gland. Like cortisol, ACTH levels are generally high in the morning and fall throughout the day.

Once ACTH reaches the adrenal glands, it binds on to specific receptors, causing the adrenal glands to secrete more cortisol. It also increases production of other hormones such as adrenaline and noradrenaline.

An ACTH test is normally performed on people whose cortisol hormone levels are abnormal. An ACTH test can help to diagnose adrenal or pituitary diseases such as Cushing's syndrome, Cushing's disease, Addison's disease, adrenal tumours, and pituitary tumours. SYMPTOMS

This test measures the levels of ACTH in your blood.
