Order Aldosterone-to-Renin Ratio Test | Lab TestThe aldosterone-to-renin ratio test measures two hormones that jointly regulate blood pressure and sodium 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 influence each other, comparing their concentrations can reveal whether aldosterone production is inappropriately high for the prevailing renin level.
About Aldosterone-to-Renin Ratio Test | Lab Test in Normal
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.
Aldosterone and renin are typically measured together from a blood sample. The ratio is calculated by dividing the aldosterone concentration by the renin concentration, and the result is interpreted alongside the individual hormone values rather than in isolation.
Primary aldosteronism is a recognized cause of secondary hypertension. It occurs when aldosterone secretion remains elevated despite suppressed renin, a pattern that distinguishes it from other forms of high blood pressure. Because the condition is not always accompanied by low potassium, the ratio can help identify it when other findings are inconclusive.
Results are influenced by factors such as posture, time of day, dietary sodium, potassium status, and certain medications. For this reason, clinicians interpret the ratio in the context of the person's overall presentation and may repeat or confirm an abnormal result with additional testing.
