Its ratio is built from aldosterone in ng/dL and direct renin in pg/mL, so it is read here as ng/dL per pg/mL (the same as ng/dL per ng/L), which also matches the Endocrine Society's 4.0 cut point for direct renin in ng/L. An earlier ARUP version (effective May 2023) printed 0.1–3.7, and ARUP's fact sheet (ARUP Consult) lists 3.7 when aldosterone is above 15 ng/dL. Cleveland Clinic Laboratories (also a direct-renin CLIA test) describes a ratio below 3.8 as normal. Labs that report direct renin in mIU/L get a ratio on a different scale. Use the range printed on your own report.","sources":[{"title":"Aldosterone and Renin Direct, With Ratio (test 3005949)","url":"https://ltd.aruplab.com/Tests/Pub/3005949","publisher":"ARUP Laboratories"},{"title":"Aldosterone-Renin Ratio (Test Fact Sheet)","url":"https://arupconsult.com/ati/aldosterone-renin-ratio","publisher":"ARUP Consult","year":2026},{"title":"Aldosterone/Direct Renin Ratio (test ALDREN)","url":"https://clevelandcliniclabs.com/test/aldosterone-direct-renin-ratio/","publisher":"Cleveland Clinic Laboratories"}]}],"review":{"status":"ai-verified","label":"AI-verified against cited sources.
