Stage Serum creatinine criteria MDRD eGFR criteria Anuria criteria Stage Aerum creatinine Stage
Risk >1.5× baseline over 7 days >25% decrease over 7 days 1 > 1.5× baseline or >26 mmol/l increase over 48 hours 1 >26 mmol/l increase over 24 h or >44 mmol/l over 48 h
Injury >2× baseline over 7 days >50% decrease over 7 days 2 >2× baseline over 48 hours 2 >44 mmol/l increase over 24 h or >88 mmol/l over 48 h
Failure >3× baseline over 7 days >75% decrease over 7 days anuria for >12 h 3 >3× baseline or 44 mmol/l increase if baseline > 300 mmol/l over 48 hours or any RRT or anuria for >12 h 3 >88 mmol/l increase over 24 h or >132 mmol/l over 48 h
