  • eGFR by the MDRD formula; UACR >30 mg/g. CKD stage 1 = normal renal function (eGFR ≥90 ml/min per 1.73 m2) and markers of kidney damage (proteinuria, hematuria, or morphological abnormalities); CKD stage 2 = eGFR <90 ml/min per 1.73 m2 and markers of kidney damage; CKD stage 3 = eGFR <60 ml/min per 1.73 m2.
