A 62-year-old with T2D and eGFR 55 mL/min/1.73 m² has urine albumin-to-creatinine ratio (ACR) 85 mg/g. Which statement best reflects current CKD evaluation?AAlbuminuria <300 mg/g is normal and not CKDBConfirm albuminuria persistence and stage CKD using GFR and albuminuria categories (A1 <30, A2 30-300, A3 >300 mg/g) for ≥3 monthsCeGFR alone defines CKD stagingDCystatin C is not recommended for GFR estimationERepeat testing is unnecessary once ACR is elevatedCheck my answer
