Indicator Explainer
Aldosterone
A mineralocorticoid hormone produced by aldosterone synthase (CYP11B2) in the zona glomerulosa of the adrenal cortex. Aldosterone binds to mineralocorticoid receptors (MR; NR3C2) and MR-aldosterone complexes regulate the expression of genes involved in the retention of sodium, the secretion of potassium, and water reabsorption, all of which may result increased blood pressure.
This page explains what the indicator is and how results are interpreted in general terms. Reference ranges depend on the laboratory, the method, and your own situation — no single “normal value” applies to everyone. This page is health information, not a diagnosis. For symptoms, treatment, or urgent concerns, contact a healthcare professional.
