Order Aldosterone-to-Renin Ratio Test | Lab TestThe aldosterone-to-renin ratio test measures two hormones that jointly regulate blood pressure and salt balance. Aldosterone prompts the kidneys to retain sodium and excrete potassium, while renin is the enzyme the kidneys release to initiate that process. Comparing the two values in a single ratio helps characterize how the adrenal and renal systems are interacting.
About Aldosterone-to-Renin Ratio Test | Lab Test in Greenville
The aldosterone-to-renin ratio is a paired hormone measurement used to evaluate the relationship between aldosterone production and renin activity.
Aldosterone is produced by the adrenal glands and acts on the kidneys to conserve sodium and water while promoting potassium loss. Renin is released by the kidneys when blood pressure or sodium delivery falls, and it normally drives aldosterone upward. Under healthy conditions the two hormones move together, so a change in one is mirrored by a change in the other.
The ratio expresses aldosterone relative to renin. When aldosterone remains elevated while renin stays suppressed, the ratio rises. This pattern is the reason the test is often used to screen for primary aldosteronism, a condition in which the adrenal glands produce excess aldosterone independently of the renin signal. Because aldosterone excess can raise blood pressure and lower potassium, identifying the pattern can clarify why hypertension is present or difficult to manage.
Results are interpreted as a pair rather than as isolated numbers, and the ratio is only one piece of a broader clinical picture. Medications, sodium intake, potassium levels, posture, and time of day can all influence aldosterone and renin, so the ordering clinician considers these factors when reading the result. The test does not diagnose a condition on its own; it provides a focused measurement that supports further evaluation when the findings warrant it.
