Renin i plasma

TīmeklisThe renin in plasma is allowed to act on the plasma's endogenous substrate, angiotensinogen, producing angiotensin I. This is measured by mass … Tīmeklis2004. gada 1. nov. · Plasma renin is therefore the initiator of the renin-angiotensin-aldosterone system, which has an important role in the homeostasis of water and electrolyte balance and in the regulation of arterial pressure. In most studies, circulating renin has been estimated by assays of plasma renin activity (PRA).

Plasma renin activity (PRA), also known as the renin (active) assay or random plasma renin, is a measure of the activity of the plasma enzyme renin, which plays a major role in the body's regulation of blood pressure, thirst, and urine output. Measure of direct renin concentration (DRC) is technically more demanding, and hence PRA is used instead.
