Primary aldosteronism is a specifically treatable and potentially curable form of secondary hypertension. The aldosterone/plasma renin activity ratio (ARR) is routinely used as a screening test. Antihypertensive therapy can interfere with the interpretation of this parameter, but a correct washout period can be potentially harmful.

The guideline indicates that the diagnosis of PA provides the opportunity The aldosterone-to-renin ratio is the best initial test to determine whether a patient with hypertension should have further evaluation for hyperaldosteronism.

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 … Combined inhibition of the renin–angiotensin–aldosterone system was first evaluated on the basis of three pathophysiological considerations. 19 First, any renin–angiotensin–aldosterone inhibition with an ACE inhibitor or angiotensin receptor antagonist is incomplete due to substantial redundancy built into human physiological systems.

Standing cardiac output was lowered after propranolol treatment (P=0.01) but was minimally changed after training. The aldosterone:renin ratio during 2-hour standing remained unchanged after propranolol treatment (4.1±1.7 [SD] before versus 3.9±2.0 after; P=0.46) but modestly increased after training (5.2±2.9 versus 6.5±3.0; P=0.05).

Material and methods Patients 62 patients directed for evaluation of renin-aldosterone-angiotensin system (11 males, 51 females, mean age 50, range 20–76 years), after setting final diagnosis, were The ratios of aldosterone / plasma renin activity (ARR) versus aldosterone / direct renin concentration (ADRR) 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.

aldosterone/plasma renin activity ratio (ARR) is routinely used as a screening test. Antihypertensive therapy can interfere with the interpretation of this parameter, but a correct washout period can be potentially harmful. We have investigated the effects of therapy with atenolol, amlodipine, doxazosin, fosinopril, and irbesartan on the ARR in Because of the demonstration that the plasma aldosterone concentration (PAC)/plasma renin activity (PRA) ratio (ARR) is the most reliable method of screening for PA, 8 this test became widely used in hypertensive clinics. 8–11 PAC and the PRA measurements must be performed in patients in washout from all hypertensive drugs to avoid false-positive and false-negative results. importance of renal vein renin ratios for lateralisation and diagnosis.

Below is a table from UpToDate and originally from the J Clin Endocrinol Metab which shows cut-off values for the ratio, depending on the type of units used to measure each component value (source: UptoDate) The decrease in renin concentration by beta-blockers leads to an increase in the ratio of aldosterone to renin, and thus to false-positive results in patients with essential hypertension.

The renin-angiotensin system (RAS) plays a crucial role in the regulation of renal, cardiac, and vascular physiology, and its activation is central to many common pathologic conditions including hypertension, heart failure, and renal disease. An overview of the normal function of the system, as well as ramifications of its dysfunction 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. Primary aldosteronism (PA) is estimated to occur in 5–12% of patients with hypertension. Assessment of aldosterone / plasma renin activity (PRA) ratio (ARR) has been used as a screening test in patients suspected of PA. Direct determination of renin (DRC) and calculation of aldosterone / direct renin concentration ratio (ADRR) could be 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).

Expect: low renin, high aldosterone→ elevated ratio. Aldosterone/renin ratio (ARR) is the screening test of choice for PA.
