The Plasma Renin Activity Test measures the rate at which renin, an enzyme produced by the kidneys, generates angiotensin I. This activity reflects the body’s regulation of blood pressure, fluid balance, and electrolyte homeostasis. Abnormal renin activity may indicate forms of hypertension, adrenal gland disorders, or underlying kidney disease. Clinicians use this test to evaluate the aldosterone-renin ratio, investigate secondary hypertension, and assess systemic conditions affecting cardiovascular and renal function. Results help guide diagnostic decision-making and inform targeted treatment strategies.
