2021-02-09 · The renin - aldosterone ratio is a value that is calculated after measuring the concentrations of the hormones renin and aldosterone in the blood. It is most commonly checked as part of a diagnostic evaluation of high blood pressure, also known as hypertension.

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

J Low aldosterone and morning cortisol levels, hyperkalemia, increased plasma renin level, low or increased adrenocorticotropic hormone level (cause-dependent), urinary sodium > 20 mEq per L Potassim-aldosterone-renin interrelationships. J Clin Endocrinol Metab 1975; 41:153. Terker AS, Zhang C, McCormick JA, et al. Potassium modulates electrolyte balance and blood pressure through effects on distal cell voltage and chloride. A urine potassium-to-creatinine ratio corrects for variations in urine volume. When this ratio is greater than 13 mEq/g, renal potassium losses should be suspected.

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. 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). 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).

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).

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. Aldosterone-to-renin ratio (ARR) is the mass concentration of aldosterone divided by the plasma renin activity in blood plasma. The aldosterone/renin ratio is recommended as screening tool for primary hyperaldosteronism.[1] From the laboratory perspective, this usually involves measuring both aldosterone and renin and calculating an aldosterone-to-renin ratio (ARR).

Renin (ng/mL/h) Renin (pmol/L/min) Aldosterone (as ng/dL) 30. 2.5. Aldosterone (as pmol/L) 750. 60. The ARR compares the amount of aldosterone to that of renin, and the resulting number – a ratio – is then compared with a “cutoff” value currently set at 30 (or 750 when measurements are expressed in SI units).

High blood pressure accompanied by low potassium is the usual set of findings that lead the doctor to check these two tests. 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.

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.
