Angiotensin II, Plasma
Also known as: ANGIO II
Use
The Angiotensin II, Plasma test is essential for evaluating the concentration of angiotensin II in the blood plasma. It plays a critical role in diagnosing conditions related to blood pressure regulation and electrolyte balance. This test is often utilized to assess the renin-angiotensin system, particularly when conditions such as hypertension, heart failure, or kidney disorders are suspected. It helps in determining the efficacy of treatments affecting angiotensin II levels and provides insights into the pathophysiology of various cardiovascular and renal disorders.
