Order Aldosterone-to-Renin Ratio Test | Lab TestThe aldosterone-to-renin ratio test measures two hormones that together regulate blood pressure and the body's balance of sodium and potassium. Aldosterone is produced by the adrenal glands and prompts the kidneys to retain sodium and excrete potassium. Renin is an enzyme released by the kidneys when blood pressure or sodium levels fall. Because the two hormones move in opposite directions under normal conditions, comparing them as a ratio can reveal patterns that neither measurement shows alone.
About Aldosterone-to-Renin Ratio Test | Lab Test in Wheaton
The aldosterone-to-renin ratio is most often used to screen for primary aldosteronism, a condition in which the adrenal glands produce too much aldosterone.
In primary aldosteronism, excess aldosterone drives sodium retention and potassium loss, which can raise blood pressure and lower potassium levels. Ordinarily, high aldosterone would suppress renin production, so an elevated aldosterone level alongside a suppressed renin level produces a high ratio. That combination is the central finding the test is designed to detect.
The test is typically considered for people with persistent high blood pressure, especially when it is resistant to treatment, begins at a young age, or occurs alongside low potassium. It may also be used when an adrenal mass is found incidentally or when there is a family history of early-onset hypertension or stroke. Because aldosterone and renin fluctuate throughout the day and respond to posture, sodium intake, and many medications, results are interpreted alongside the clinical picture rather than in isolation.
Several factors can affect the ratio. Diuretics, ACE inhibitors, angiotensin receptor blockers, and mineralocorticoid receptor antagonists can alter both hormones, and potassium levels, salt intake, and time of day can shift results as well. A clinician may adjust or pause certain medications before testing and may repeat an abnormal ratio or confirm it with additional testing. The ratio is a screening tool, not a diagnosis on its own.
