Objectives . Aldosterone-to-plasma renin activity ratio (ARR) derived from traditional radioimmunoassay (RIA) is widely used to detect primary aldosteronism (PA). Recently, aldosterone-to-direct renin concentration ratio (ADRR), which is calculated by direct renin concentration (DRC) measured by chemiluminescent immunoassay (CLIA), is proposed to replace ARR as the screening test method for …

Any patient with one or more of these criteria should be screened initially with the aldosterone-to-renin ratio (ARR), regarded as the gold standard and most reliable screening test for PA (1). However, due to several reasons, the ARR should be interpreted in the context of the plasma aldosterone concentration and plasma renin activity (PRA) or plasma direct renin concentration (DRC).

A high plasma aldosterone and suppressed plasma renin activity is suggestive of primary hyperaldosteronism. Samples are sent to Charing Cross Hospital, London. The ranges they quote are as follows; Random plasma aldosterone 90 - 700 pmol/L Random plasma renin activity 0.5 – 3.5 nmol/L/hr Aldosterone/PRA ratio <680 Conn’s unlikely A high ratio of serum aldosterone (SA) in ng/dL to plasma renin activity (PRA) in ng/mL per hour is a positive screening test result, a finding that warrants further testing. An SA:PRA ratio of 20 or higher is only interpretable with an SA of 15 ng/dL or higher and indicates probable primary aldosteronism.

Plasma Aldosterone-Renin ratio greatly assists in diagnosis. High plasma aldosterone levels occur in primary aldosteronism, where the aldosterone/PRA ratio is > 30.5 (pmol/L)/(mIU/L) (Adult) using Endolab methods.

Labcorp.com 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).

Further, it recommends the plasma aldosterone to renin ratio (ARR), as the test of choice for screening for PA. However, the ARR is a highly variable test with reported diagnostic sensitivities and specificities ranging from 66% to 100% and 61% to 100%, respectively. 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).

Aldosteron-reninkvot (ARR) Det mest känsliga screeningtestet på RAAS-systemets funktion. Vid en autonom produktion av aldosteron kommer således renin att successivt hämmas, även om både renin och aldosteron ligger inom normalområdet. Internationellt har plasma-Renin Aktivitet (PRA) använts vid beräkning av gränsvärden för kvoter.

bReference range for renin activity is for an adult with a normal sodium diet. Figure 1.

The overall sensitivity, specificity, area under the curve, and diagnostic odds ratio of ADRR were 0.89 (95% confidence interval (CI) 0.84-0.93), 0.96 (95% CI 0.95-0.98), 0.985 and 324 respectively, with substantial heterogeneity. Meta-regression showed that antihypertensive status affects the ADRR and may account for the heterogeneity (p=0.03).

Eine erhöhte Aldosteron- und erniedrigte Renin-Konzentration, d.h. eine Erhöhung des ARQ, deutet auf einen primären Hyperaldosteronismus hin. Das Ergebnis ist methodenabhängig , entsprechend müssen die laborspezifischen Referenzwerte beachtet werden.

Even if potassium is normal, testing may be done if typical medications do not control the high blood pressure or if hypertension develops at an early age. The aldosterone:renin ratio (ARR) is the recommended screening test for PA in individuals with hypertension with or without hypokalemia. 1–3 Elevations in the ratio are predominantly dependent on renin measurements,2 12 thus any alteration to the renin assay will have an impact on 1 INTRODUCTION.

Renin: Collect EDTA blood; separate plasma from cells immediately by centrifugation; freeze plasma immediately. Due to sample stability issues, only frozen samples can be accepted for analysis. Minimum volume: Aldosterone: 0.7mL serum or plasma Renin: 1.15 mL EDTA-plasma Transport: Send aldosterone and renin samples frozen without delay to: Aldosterone:Renin Ratio. Aldosterone:renin ratio is useful in the investigation of hypertension, especially if a patient has resistant hypertension, is persistently hypokalaemic (but note that 50% patients with aldosterone producing adenomas are reportedly normokalaemic), or if no obvious cause is found for the hypertension in a younger patient. 2019-05-17 Aldosterone/renin ratio >2000 Conn’s likely if renin >0.3 pmol/mL/h. 800 – 2000 Possibly Conn’s, investigate further <800 Conn’s unlikely.
