Criteria for Diagnosis of AKI
The diagnosis of AKI is based on the Kidney Disease Improving Global Outcomes (KDIGO) criteria, which include:
- Serum Creatinine Increase:
- An increase in serum creatinine by ≥0.3 mg/dL within 48 hours, or
- An increase in serum creatinine to ≥1.5 times the baseline value within the prior 7 days.
- Urine Output Reduction:
- A urine output of <0.5 mL/kg/hour for at least 6 hours.
These criteria help clinicians identify AKI early and intervene promptly.
