The following information for aldosterone-renin ratio (ARR) testing is provided to ensure proper preparation for specimen collection and test interpretation.
A low level of renin may be due to: Adrenal glands that release too much aldosterone hormone (hyperaldosteronism); High blood pressure that is salt- sensitive

Although the aldosterone/renin ratio (ARR) is the most reliable screening test for primary aldo-steronism, false positives and negatives occur. Dietary salt restriction, concomitant malignant or renovascular hypertension, pregnancy and treatment with diuretics (including spironolactone), dihydropyri … Aldosterone-to-renin ratio (ARR) is the mass concentration of aldosterone divided by the plasma renin activity or by serum renin concentration in blood. The aldosterone/renin ratio is recommended as screening tool for primary hyperaldosteronism. The consensus group went on to recommend the use of the plasma aldosterone:renin ratio (ARR) to detect cases of PA in these patient groups. 14-20 The ARR is calculated as the ratio of the serum aldosterone (in ng/dL) divided by serum plasma renin activity (in ng/mL/hour).

High plasma aldosterone levels occur in primary aldosteronism, where the aldosterone/PRA ratio is > 30.5 (pmol/L)/(mIU/L) (Adult) using Endolab methods. Drugs reducing the renin‐angiotensin‐aldosterone system (RAAS) activation include beta‐blockers and centrally acting agents such as clonidine and alpha‐methyldopa.
The aldosterone-to-renin ratio was proposed as a sensitive screening test because most cases of primary aldosteronism have normal aldosterone levels. However, due to the variation of aldosterone and renin measurement methods, specifying a universal aldosterone-to-renin ratio is impossible.

Diagnosis of the treatable disorder PA is difficult, since aldosterone/renin ratio in serum and adrenal vein catheterization have low sensitivity.

Aldosterone, LC/MS and Plasma Renin Activity, LC/MS/MS; Methodology. Chromatography/Mass Spectrometry. Assay Category. This test was developed and its analytical performance characteristics have been determined by Quest Diagnostics. It has not been cleared or approved by FDA.
The aldosterone-to-renin ratio (ARR)—that is, the ratio of plasma aldosterone ( expressed in ng/dL) to plasma renin activity (PRA, expressed in ng/mL/h)—is the 15 Dec 2020 ALD tests are often combined with tests for renin, a hormone made by the kidneys. Renin signals the adrenal glands to make ALD. The combined Primary aldosteronism is a specifically treatable and potentially curable form of secondary hypertension.
