Description:

Aldosterone: Renin Ratio Blood Test (Labcorp)

The Aldosterone/Renin Ratio Test is used to aid in diagnosing conditions related to irregular blood pressure or hypertension.  Results for this test include measurements for aldosterone, renin activity, and aldosterone/renin ratio.  Aldosterone is a hormone produced by the adrenal glands that helps to regulate the levels of sodium and potassium in the blood as well as controlling blood pressure and volume.  Renin is an enzyme produced by the kidneys that stimulates the production of Aldosterone.  Together, Aldosterone and Renin help maintain healthy blood pressure levels.   

An aldosterone/renin blood test is often ordered when a person has high blood pressure, especially if they also have abnormal potassium levels or are not responding to blood pressure medication.  This testing may also be ordered when someone develops hypertension at an early age.  High blood pressure caused by irregular aldosterone production is typically treatable if it is detected early.  Tests that measure Blood Aldosterone by itself as well as 24-hour Urine Aldosterone are also available. 

Aldosterone testing can also aid in diagnosing conditions that affect the adrenal and pituitary glands such as Addison's Disease.  In these cases, it is often ordered with other tests such as Cortisol and ACTH.

Turnaround for this test is typically 1-5 business days.

Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.

Requirements:

Maintain an unrestricted dietary salt intake prior to testing. Washout of all interfering antihypertensive medications may be considered in people with mild hypertension, but is potentially problematic in others and perhaps unnecessary in that medications with minimal effect on the ARR can be used in their place.  Do not take drugs that markedly affect the ARR for at least four weeks prior to blood collection. These drugs include Spironolactone, eplerenone, amiloride, and triamterene Potassium-wasting diuretics, and Products derived from liquorice root (eg, confectionary licorice, chewing tobacco).

Collect blood mid-morning, after being up (sitting, standing, or walking) for at least two hours and seated for 5 to 15 minutes.
