Aldosterone Test

The Aldosterone Test measures the concentration of aldosterone, a hormone produced by the adrenal cortex that plays a key role in regulating blood pressure as well as sodium and potassium balance. Abnormal aldosterone levels may suggest conditions such as primary aldosteronism, adrenal adenomas or hyperplasia, kidney dysfunction, or secondary forms of hypertension. Clinicians use this test to evaluate unexplained high blood pressure, assess electrolyte abnormalities, and investigate suspected adrenal disorders. Results help inform diagnosis, guide targeted treatment, and support ongoing management of cardiovascular and endocrine health.
