Clinical validation for the aldosterone-to-renin ratio and aldosterone suppression testing … 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). 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. BACKGROUND: The ratio of plasma aldosterone concentration to plasma renin activity (PRA) is considered the screening test of choice for primary aldosteronism.

ACE (Angiotensin-converting enzyme) inhibitors are known to raise renin and lower aldosterone levels, thereby causing false-negative ARR results. 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). Hva Er Renin-aldosteron Ratio? Renin-aldosteron-forholdet er en verdi som beregnes etter å måle konsentrasjoner av hormoner renin og aldosteron i blodet. Det er oftest kontrolleres som en del av en diagnostisk evaluering av høyt blodtrykk, også kjent som hypertensjon.

Current guidelines recommend the use of the aldosterone‐to‐renin ratio (ARR) for the screening of patients suspected of having primary aldosteronism (PA). 1 Aldosterone can be measured using either plasma or serum concentrations (PAC and SAC respectively), while renin can be determined using either plasma renin activity or direct renin concentration (PRA and DRC, respectively). 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 20 or higher is only interpretable with an SA of 15 ng/dL or higher and indicates probable primary aldosteronism.

The objective of this study was to investigate the association between the estimated glomerular filtration rate (eGFR) and ARR as well as its effect on screening for PA. Methods.

Forhøyet ARR, ratio >35, indikerer hyperaldosteronisme. Både aldosteron og renin er påvirket av en rekke blodtrykks-medikamenter, østrogen og NSAID. Aldosterone:renin ratio cutoffs were then determined for the direct renin concentration assay. A highly probable case of primary aldosteronism corresponded to a cutoff of >100 pmol L −1 mIU −1 L with hypokalemia.

1 INTRODUCTION. Current guidelines recommend the use of the aldosterone‐to‐renin ratio (ARR) for the screening of patients suspected of having primary aldosteronism (PA).

However, there are various con-founding factors, including medication, that may influence the levels of renin and/or aldosterone and consequently the ARR. While with - drawal of antihypertensive treatment prior to screening is advisable, 2007-07-01 aldosterone / direct renin concentration ratio (ADRR) could be similarly useful for screening patients suspected of PA. So far, not very many comparative studies evaluat-ing both these indices have been performed.5–7 Aim of the study The aim of the study was to determine whether the ratio serum aldosterone / PRA (ARR) can be replaced by the Showing results for aldosterone renin ratio Diagnosis of primary aldosteronism View in Chinese …retrospective, multicenter review, more widespread use of the plasma aldosterone to renin ratio (plasma aldosterone concentration/plasma renin activity [ PAC/PRA ] ratio) as a case-detection test in hypertensive patients … P-Aldosteron och P-Renin analyseras från samma rör. Notera om patienten var stående eller liggande vid provtagning pga olika referensintervall. Provtagning bör ske på morgonen efter kort vila (15-30 min). The aldosterone-to-renin ratio was proposed as a sensitive screening test because most cases of primary aldosteronism have normal aldosterone levels.

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.

Notera om patienten var stående eller liggande vid provtagning pga olika referensintervall. Provtagning bör ske på morgonen efter kort vila (15-30 min). 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.
