Kidney Disease: Improving Global Outcomes clinical practice guidelines for identification of acute kidney disease (AKD) and chronic kidney disease (CKD)
| AKD | eGFR <60 mL·min−1 per 1.73 m2 for <3 months# |
| or | |
| Decrease in eGFR by >35% | |
| or | |
| Increase in serum creatinine >50% for <3 months | |
| CKD | eGFR <60 mL·min−1 per 1.73 m2 for >3 months |
eGFR: estimated glomerular filtration rate. #: in patients with a baseline eGFR <60 mL·min−1 per 1.73 m2 only changes in eGFR and serum creatinine during the next 3 months were used as criteria for AKD.
