Order Aldosterone-to-Renin Ratio Test | Lab TestThe aldosterone-to-renin ratio test measures two hormones that jointly regulate blood pressure and fluid balance. Because aldosterone and renin influence each other through a feedback loop, comparing them as a ratio can reveal patterns that neither value shows alone.
About Aldosterone-to-Renin Ratio Test | Lab Test in Vineyard
The aldosterone-to-renin ratio, often abbreviated ARR, is a laboratory calculation derived from a blood aldosterone measurement and a blood renin measurement.
Aldosterone is a steroid hormone produced by the adrenal glands. It prompts the kidneys to retain sodium and excrete potassium, which raises blood volume and, in turn, blood pressure. Renin is an enzyme released by the kidneys when blood pressure or sodium levels fall; renin triggers a cascade that ultimately stimulates aldosterone production.
Under normal conditions, this relationship is reciprocal: when renin rises, aldosterone rises, and when aldosterone is abundant, renin should fall. The ratio expresses aldosterone relative to renin, so a disproportionately high aldosterone level alongside a suppressed renin level produces a high ratio.
Clinicians order the ratio chiefly when evaluating hypertension that is resistant, early in onset, or accompanied by low potassium. The result is interpreted alongside the individual hormone values and the clinical picture; it is a screening and investigative tool rather than a standalone diagnosis.
