Order Aldosterone-to-Renin Ratio Test | Lab TestThe aldosterone-to-renin ratio is a calculated value derived from two separate hormone measurements: aldosterone and renin. Rather than being a standalone assay, it serves as a screening index that helps clinicians interpret the relationship between these hormones in the context of blood pressure regulation.
About Aldosterone-to-Renin Ratio Test | Lab Test in Apex
This test is used to evaluate the balance between aldosterone and renin, particularly in individuals with elevated blood pressure or those at higher risk for hypertension.
Aldosterone is a steroid hormone produced by the adrenal glands. It helps regulate sodium and potassium levels by promoting sodium retention and potassium excretion in the kidneys, which in turn influences blood volume and blood pressure.
Renin is an enzyme released by the kidneys in response to low blood pressure, low sodium levels, or sympathetic nerve activity. It initiates a cascade that ultimately stimulates aldosterone production, forming the renin-angiotensin-aldosterone system.
Because aldosterone and renin are interdependent, measuring them together and calculating their ratio provides a more informative picture than either value alone. An elevated ratio may suggest that aldosterone production is inappropriate relative to renin, a pattern that warrants further clinical investigation.
