Human vasopressin, also called antidiuretic hormone (ADH), is a hormone that has two primary functions. First, it increases the amount of solute-free water reabsorbed back into the circulation from the filtrate in the kidney tubules of the nephrons. Second, AVP constricts arterioles, which increases peripheral vascular resistance and raises arterial blood pressure. Vasopressin regulates the tonicity of body fluids, in response to hypertonicity is release into the circulation and causes the kidneys to reabsorb solute-free water and return it to the circulation from the tubules of the nephron, thus returning the tonicity of the body fluids toward normal. An incidental consequence of this renal reabsorption of water is concentrated urine and reduced urine volume. AVP released in high concentrations may also raise blood pressure by inducing moderate vasoconstriction.

NovoLytiX has an variety of products to determine vasopressin levels in order to find individual shifts in blood, plasma or urine.
