ADRENOCORTICOTROPIC HORMONE (ACTH)

The adrenocorticotropic hormone (ACTH) test measures the level of ACTH in the blood. ACTH is produced by the pituitary gland and stimulates the adrenal glands to release cortisol. This test is used to diagnose and monitor disorders of the pituitary or adrenal glands, such as Addison’s disease, Cushing’s syndrome, and adrenal insufficiency. Abnormal levels of ACTH can indicate issues with the hypothalamic-pituitary-adrenal axis. By measuring ACTH levels alongside cortisol levels, healthcare providers can determine the underlying cause of hormone imbalances and develop appropriate treatment plans.
