ADH stands for AntiDiuretic Hormone and is also known as argipressin, vasopressin or arginine vasopressin. It is a hormone synthesized by our hypothalamus and secreted by the pituitary gland. It is primarily responsible for maintaining the water levels in our (and that of other mammals) body. When the body's water content falls down (that is, we get dehydrated), ADH is released and this causes our kidneys to reduce the quantity of water exiting our body through urine. Under such circumstances, the very dilute urine, on passage through the kidneys, gets concentrated and part of its water content is retained. This is made possible by the action of ADH, which increases the reabsorption of water by our kidneys. When we have symptoms like excess thirst, urination in large amounts, low sodium body content, etc., we have to undergo ADH blood test to check if everything is alright with this important hormone. 

Hope this helps.

ADH is the Antidiuretic hormone. It is produced in a part of brain called the hypothalamus. It is then stored and released by the pituatary gland which is at the base of the brain . ADH has an antidiuretic action which prevents the production of dilute urine. It also mainttains blood pressure and blood volume along with controlling the amount of water in the tissues.

ADH hormone is the hormone produced by the specific area in the brain called hypothalamus. The produced substance is then stored in the pituitary gland (small gland that is in the base of the brain.). The ADH hormone acts on the kidney- it controls the water excreted in the urine.
