Measures the hormone that regulates blood pressure and electrolyte balance. Aldosterone is a hormone produced by the adrenal glands that plays a central role in regulating blood pressure by controlling sodium and potassium balance. Elevated aldosterone (hyperaldosteronism) is a treatable but often overlooked cause of resistant hypertension, while low levels can indicate adrenal insufficiency. This test is especially important for patients with high blood pressure that does not respond well to standard medications. **Clinical use:** Hormone testing measures the chemical messengers that regulate energy, mood, sex drive, weight, and reproduction — helping pinpoint imbalances that cause a wide range of symptoms. ## Who should order it? Anyone with unexplained fatigue, mood changes, libido changes, weight changes, irregular cycles, or considering hormone replacement therapy. ## Biomarkers measured - [Aldosterone](https://www.test-well.com/biomarkers/aldosterone) ## Price by lab | Lab | Test price | All-in (with $6 fee) | Notes | | --- | --- | --- | --- | | Quest Diagnostics | $61.99 | $67.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | | Labcorp | $78.99 | $84.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | Rhode Island is not served.
