KDIGO AKI stages
Stage 1–3 based on creatinine rise (relative and absolute), urine output, renal replacement therapy and eGFR < 35 in children

Frequently asked questions
KDIGO AKI stages: What does this calculator compute?
Classifies acute kidney injury according to KDIGO 2012: serum creatinine 1.5–1.9-fold or rise ≥ 0.3 mg/dl in 48 h (stage 1), 2.0–2.9-fold (2), ≥ 3-fold, ≥ 4.0 mg/dl, renal replacement therapy or eGFR < 35 ml/min/1.73 m² in children under 18 years (3) as well as urine output < 0.5 ml/kg/h over 6–12 h / ≥ 12 h or < 0.3 ml/kg/h over ≥ 24 h or anuria ≥ 12 h; the more severe criterion applies.
