A Plasma Renin helps determine the cause of hypertension in cases where signs of kidney disease are present.
A plasma renin may be ordered when a patient has high blood pressure and low potassium. Even if potassium is normal, testing may be done if typical medications do not control the high blood pressure or if hypertension develops at an early age. Primary aldosteronism is a potentially curable form of hypertension, so it is important to detect and treat it properly.
