This test measures levels of drenocorticotropic hormone (ACTH), which is also called adrenocorticotropin and corticotropin, a hormone made in the anterior pituitary gland that tells the adrenal glands to release cortisol, DHEA, and aldosterone. The ACTH plasma test quantifies the blood's level of ACTH. A patient's blood is drawn for the test and then sent to a lab for examination. The test findings enable the diagnosis of ailments such as Addison's disease, Cushing's syndrome, and adrenal tumors

The PTH test is used to help identify hyperparathyroidism, to find the cause of abnormal calcium levels, or to check the status of chronic kidney disease. PTH controls calcium and phosphorus levels in the blood.
