The ADH test analyses the amount of ADH present in the blood.
The ADH test analyses the amount of ADH present in the blood. This test is mainly used to diagnose and determine the main causes of oversecretion and the deficiency of the antidiuretic hormone in the blood cells. This test is often based on osmolality as well as electrolytes of blood and urine. As per reports, the normal range for ADH is 1-5 picograms per millilitre (pg/mL).
Antidiuretic hormone (ADH) is also called Vasopressin. It is a naturally occurring hormone that helps in controlling various physical processes and several life-threatening conditions, including bleeding abnormalities and septic shocks. It is mainly involved in regulating and balancing the amount of water in the blood and increasing the glomerular blood flow by increasing the blood pressure. Higher the concentrations of ADH tightens the blood vessels, which increases the blood pressure. The ADH is activated by the posterior portion of the pituitary gland. The anti-diuretic hormone is secreted by the neurohypophysis of the pituitary gland . Since it stimulates the constriction of blood vessels and results in an increase in blood pressure, therefore it is called vasopressin. The ADH is produced in the hypothalamus, which is stored and secreted by the pituitary gland which lies just beneath the base of the brain. Read more: Hypothalamus
The anti-diuretic hormone is involved in the:
The release of ADH into the bloodstream is regulated by a number of factors:
The low level of Antidiuretic hormone in the blood cells results in:
The higher level of Antidiuretic hormone in the blood cells results in:
The disorders of the antidiuretic hormone are mainly caused either by a higher or lower level of ADH hormones. The disorders include:
