Order Aldosterone-to-Renin Ratio Test | Lab TestThe aldosterone-to-renin ratio test measures two hormones that work together to regulate blood pressure and fluid balance. 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 respond to each other, comparing their concentrations can reveal whether aldosterone production is inappropriately high relative to renin.
About Aldosterone-to-Renin Ratio Test | Lab Test in Greenwood
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.
Primary aldosteronism is a common secondary cause of hypertension, meaning the elevated blood pressure stems from an identifiable hormonal source rather than lifestyle or age alone. Because the condition can be treated with medication or, in some cases, surgery, distinguishing it from essential hypertension has practical consequences for management.
The test is generally considered for people with resistant hypertension, hypertension that begins at an unusually young age, or hypertension accompanied by low potassium. It may also be ordered when a person experiences unexplained hypokalemia or when an adrenal mass is discovered incidentally on imaging.
Results are interpreted by comparing the aldosterone concentration to the renin level, not by looking at either value in isolation. A high ratio suggests that aldosterone secretion is not being properly suppressed by the kidneys' signals. Because many medications and physiological states can influence both hormones, the ordering clinician typically reviews the ratio alongside the patient's medication list and clinical history.
