KDIGO 2012 Clinical Practice Guideline for the Evaluation and Management of CKD (Kidney Int Suppl 2013;3:1-150), albuminuria categories by ACR as printed on the National Kidney Foundation CKD card: A1 <30 mg/g normal to mildly increased; A2 30-300 mg/g moderately increased; A3 >300 mg/g severely increased. ACR (mg/g) = urine albumin (mg/L) ÷ urine creatinine (mg/L) × 1000. (2013)
