Why This Biomarker Matters

Aldosterone abnormalities can cause high blood pressure, electrolyte imbalances, and weakness. Detecting these helps diagnose and treat underlying adrenal or cardiovascular conditions.

Overview

Aldosterone is a hormone produced by your adrenal glands that regulates salt and water balance, which directly affects blood pressure. This test measures aldosterone levels in your blood. Elevated aldosterone can cause high blood pressure and low potassium levels, potentially indicating primary aldosteronism (Conn's syndrome) or secondary hyperaldosteronism from kidney disease or heart failure. Low aldosterone may suggest adrenal insufficiency.
