A positive test is a renal venous renin ratio (affected/normal) >1.5. 2. Primary aldosteronism is manifested by low renin and elevated aldosterone levels.

– 2.5 percentil 97.5 percentile. 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). Aldosterone-to-renin ratio (ARR) is the mass concentration of aldosterone divided by the plasma renin activity or by serum renin concentration in blood.
Aldosterone-to-renin ratio can be given in ng/dL per ng/(mL·h), that is, nanogram per deciliter of aldosterone per nanogram per (milliliter x hour) of renin. Also, it can be given in pmol/L per µg/(L·h), where aldosterone is given in molar concentration. The former can be converted to the latter by multiplying by 27.6. In GRA, the aldosterone to renin ratio is elevated (>300), whereas in primary hypertension, AME, and Liddle syndrome, it is not.
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). Although the aldosterone/renin ratio (ARR) is the most reliable screening test for primary aldo-steronism, false positives and negatives occur.

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. 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. Aldosterone is one of the hormones that helps keep your sodium and potassium levels normal in the blood.

Unacceptable Conditions: Common conditions under which a specimen will be rejected. Remarks: Additional specimen collection, The ARR should be measured in the context of an unrestricted sodium intake ( which should not require adjustment from normal for the majority of patients). A positive test is a renal venous renin ratio (affected/normal) >1.5. 2.

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). Aldosterone and Renin tests are usually requested by clinicians together when a patient shows high blood pressure and low potassium. 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. Ignatowska-Switalska H, Chodakowska J, Januszewicz W, Feltynowski T, Adamczyk M, Lewandowski J. Evaluation of plasma aldosterone to plasma renin activity ratio in patients with primary The aldosterone to renin ratio test, a blood test, measures the amount of aldosterone divided by the amount of renin in the blood plasma.
INVESTIGATIONS. Aldosterone/renin ratio will be normal if performed off interfering medications. May be elevated if patient receiving medications (such as beta-blockers) that cause false positives, in which case test should be repeated after such medications are withdrawn for at least 2 (and preferably 4) weeks.
B. Usual Laboratory Test Findings in Renin-Aldosterone Disorders: 1. Renal disease, such as unilateral renal artery stenosis, results in elevated renin and aldosterone levels.
Aldosterone/Renin Ratio. Aldosterone, which plays a crucial role in maintaining blood volume and blood pressure, is produced by the adrenal glands under the influence of angiotensin II. Renin is a protein produced in the kidneys, and its secretion is activated, for example, by a drop in blood pressure.
