Use

This test is used for investigating primary aldosteronism, which includes conditions like adrenal adenoma or carcinoma and adrenal cortical hyperplasia. It is also useful in evaluating secondary aldosteronism caused by conditions such as renovascular disease, salt depletion, potassium loading, cardiac failure with ascites, pregnancy, and Bartter syndrome. Aldosterone plays a key role in sodium transport across cell membranes, particularly in the distal renal tubule, and is crucial for maintaining blood pressure and blood volume.
