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.
ADH is synthetised in the hypothalamus & is transported to the posterior pituitary. ADH is a nonapeptide produced in the supraoptic and paraventricular nuclei and other areas of the hypothalamus. Its major role is in the regulation of water balance by its effect on the kidneys.
