1.0 mL serum (0.5 mL minimum) collected in serum separator tube (SST / Tiger Top)
Refrigerated (ship on frozen cold packs)
Refrigerated: 5 days

Hyperaldosteronism is a disorder caused by excessive secretion of aldosterone by the adrenal gland and may contribute to the development and progression of cardiovascular disease, renal disease, and hypertension.
- Identify etiology of elevated aldosterone with additional diagnostic tests as indicated.
- Primary Aldosteronism may be treated with eplenerone or spironolactone.
