Albuminuria categories
CategoryuACRDescription
A1<30 mg/gNormal to mildly increased
A230–300 mg/gModerately increased
A3>300 mg/gSeverely increased
uACR (mg/g) = Urine albumin (mg/L) ÷ Urine creatinine (g/L)
Persistent albuminuria generally requires repeat testing/clinical correlation; a single result alone does not establish chronic kidney disease.
