Why the Test is Performed. ADH is a hormone that is produced in a part of the brain called the hypothalamus. It is then stored and released from the pituitary gland, a small gland at the base of the brain. ADH acts on the kidneys to control the amount of water excreted in the urine.
Several hormones produced elsewhere in the body help to control the function of the kidneys. 1  Antidiuretic hormone (ADH), also known as vasopressin, is a hormone produced by neurosecretory cells in the brainâs hypothalamus. These cells extend into the posterior pituitary, which stores and releases ADH.
