On average for adults, the range of the Plasma Renin Activity runs between 0.7 and 3.3 ng/mL/hr (or 0.7 and 3.3 mcg/L/hr in SI units), and the range of the Plasma Aldosterone Concentration (PAC) goes from 7 to 30 ng/dL (or 190 to 830 pmol/L in SI units).

Healthy individuals 20 to 70 years of age were stratified into 5 consecutive decade groups, with 10 males and 10 females per decade group. However, direct renin measurements are difficult to standardize too, due to the issues on calibration or pro-renin activation. The aldosterone-to-renin ratio was proposed as a sensitive screening test because most cases of primary aldosteronism have normal aldosterone levels. An aldosterone/renin ratio (ARR) is a screening test to detect primary aldosteronism in high-risk, hypertensive individuals.

Interpretation 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 greater than or equal to 20 is only interpretable with an SA greater than or equal to 15 ng/dL and indicates probable primary aldosteronism. Aldos/Renin Ratio Optimal Result: 0 - 30 ng/dL per ng/mL/hr. The aldosterone to renin ratio test, a blood test, measures the amount of aldosterone divided by the amount of renin in the blood plasma. The ratio is used as a way to determine whether or not primary hyperaldosteronism is occurring. A high renin-aldosterone ratio suggests that too much renin is being produced by the body. Rarely, this can be due to a specialized tumor that is producing this hormone.

Renin, Direct: 2.5-45.7 pg/mL: Aldosterone/Direct Renin Calculation: 0.1-3.7 An Aldosterone/Direct Renin Ratio of greater than 3.7 is suggestive of hyperaldosteronism.

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 cutoff normal individuals from those with primary hyperaldosteronism is significantly affected by the conditions of testing, such as posture and time of day. Of note, the rate of diagnosis of PA has dramatically increased since the establishment of aldosterone/plasma renin activity ratio (ARR) as a standard screening test. 14, 15 In fact, PA is now recognized as the most common cause of secondary hypertension, accounting for 5–15% of all hypertensive patients in specialized centres. 15-22 The actual prevalence of PA in the general hypertensive population is unknown, but can be estimated from the seminal paper of Mosso et al.

Renal disease, such as unilateral renal artery stenosis, results in elevated renin and aldosterone levels. Renal venous catheterization may be helpful.

Effect of age on the renin-angiotensin-aldosterone system in normal subjects: simultaneous measurement of active and inactive renin, renin substrate, and aldosterone in plasma.

To determine the ratio, blood levels of aldosterone and renin are measured and a calculation is done by dividing the aldosterone result by the renin result. 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. Interpretation 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.

A cross-sectional study was performed in 211 healthy normotensive children (4 to 16 years old). 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 …. Factors affecting the aldosterone/renin ratio. 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.
