About Our Aldosterone-to-Renin Ratio Test

Note: Fasting is not required for this test.

This blood test is used to determine if there is too much aldosterone in the blood, especially for patients in higher risk groups for hypertension (high blood pressure). Aldosteronism is a condition in which the body's adrenal glands overproduce the hormone aldosterone.

Aldosterone causes an increase in sodium and water retention and increases potassium excretion in the kidneys, leading to hypertension.
