The cutoff normal individuals from those with primary hyperaldosteronism is significantly affected by the conditions of testing, such as posture and time of day. On average, an ARR cutoff of 23.6 ng/dL per ng/(mL·h), expressed in alternative units as 651 pmol/L per μg/(L·h), has been estimated to have a sensitivity of 97% and specificity of 94%. [2]
Plasma renin activity (PRA), also known as the renin (active) assay or random plasma renin, is a measure of the activity of the plasma enzyme renin, which plays a major role in the body's regulation of blood pressure, thirst, and urine output. Measure of direct renin concentration (DRC) is technically more demanding, and hence PRA is used instead.

Measuring aldosterone alone is not considered adequate to diagnose primary hyperaldosteronism. Rather, both renin and aldosterone are measured, and a resultant aldosterone-to-renin ratio (ARR) is used for case detection. [20] [21] A high aldosterone-to-renin ratio suggests the presence of primary hyperaldosteronism. The diagnosis is made by ...

Sheila Keen-Warren served about 16 months after pleading guilty to second-degree murder in the 1990 shooting of Marlene Warren in Wellington, Fla.
The two will visit Washington, D.C., for meetings with top lawmakers in the House of Representatives and the Senate, signaling they will work alongside Congress to slash abuse of taxpayer money.
The plasma aldosterone-to-renin ratio is calculated to determine if levels are sufficiently deranged to consider a diagnosis of hypoaldosteronism. [ citation needed ] If screening test is suggestive, a more definitive diagnosis is made by performing a saline suppression test, ambulatory salt loading test, or fludrocortisone suppression test.
