Aldosterone / Plasma Renin Direct Ratio

The Aldosterone / Plasma Renin Direct Ratio test measures the levels of aldosterone and renin in the blood, which are important for regulating blood pressure and electrolyte balance. This test is essential for diagnosing conditions such as primary hyperaldosteronism and evaluating adrenal gland function.
