Order Aldosterone-to-Renin Ratio Test | Lab TestThe aldosterone-to-renin ratio is a calculated value derived from two separate hormone measurements: aldosterone and renin. Because aldosterone and renin interact in a feedback loop that governs sodium retention, potassium balance, and blood pressure, comparing them can offer a more informative view than either result alone. This test is typically used when a clinician is evaluating hypertension that is resistant, early in onset, or accompanied by low potassium, since those patterns can point toward a hormonal contributor.
About Aldosterone-to-Renin Ratio Test | Lab Test in Bothell
The aldosterone-to-renin ratio helps assess whether aldosterone production is inappropriately high relative to the body's renin signal.
Aldosterone is a steroid hormone produced by the adrenal glands. It prompts the kidneys to retain sodium and excrete potassium, which helps regulate blood volume and blood pressure. Renin is an enzyme released by the kidneys when blood pressure or sodium delivery falls; renin then triggers a cascade that ultimately raises aldosterone. In a normal feedback loop, high aldosterone should suppress renin, and low aldosterone should allow renin to rise.
When the ratio is calculated, aldosterone is divided by renin, often expressed as a plasma aldosterone concentration over plasma renin activity or direct renin concentration. A high ratio suggests that aldosterone remains elevated even though renin is low, a pattern consistent with primary aldosteronism. Because the ratio is a screening tool rather than a diagnosis, abnormal results are usually followed by confirmatory testing and, in some cases, adrenal imaging.
Several factors can influence the ratio. Potassium levels, sodium intake, posture before the draw, time of day, and many common blood pressure medications can shift aldosterone or renin independently. For this reason, the test is interpreted alongside the individual aldosterone and renin values, electrolyte results, medication history, and the clinical picture rather than as a standalone number.
