🧪 AKIN AKI Staging
UseWhen to use: AKIN staging within a ~48-hour creatinine window or local AKIN pathways.
StrataStage reflects the higher of creatinine and urine-output criteria.
LimitsWhen not to use: missing timed baseline. · Pitfall: converting units incorrectly. · Align with KDIGO if required.

≥0.3 mg/dL or fold-change.
When to use
When to use: AKIN staging within a ~48-hour creatinine window or local AKIN pathways.
How it works
Stage 1–3 by ΔCr/fold-change or UO; RRT → stage 3.
Key points
- ≥0.3 mg/dL or fold-change.
- RRT = stage 3.
- Next: cause / KDIGO.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Baseline creatinine | 70 μmol/L |
|---|---|
| Current creatinine | 110 μmol/L |
| Urine output | <0.5 mL/kg/h × 6 h (stage 1) |
| RRT initiated | No |
→AKIN stage1
- ΔCr：0.45 mg/dL
- Ratio：1.57×
- Cr stage：1
| Baseline creatinine | 70 μmol/L |
|---|---|
| Current creatinine | 110 μmol/L |
| Urine output | <0.3 mL/kg/h × 24 h or anuria ≥12 h (stage 3) |
| RRT initiated | Yes → stage 3 |
→AKIN stage3
- ΔCr：0.45 mg/dL

FAQ
Frequently asked questions
- Does AKIN AKI Staging upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is AKIN AKI Staging calculated in practice? Can you show a worked example?
- Inputs: Baseline creatinine 70 μmol/L, Current creatinine 110 μmol/L, Urine output <0.5 mL/kg/h × 6 h (stage 1), RRT initiated No → Result: AKIN stage 1（ΔCr: 0.45 mg/dL, Ratio: 1.57×, Cr stage: 1） Inputs: Baseline creatinine 70 μmol/L, Current creatinine 110 μmol/L, Urine output <0.3 mL/kg/h × 24 h or anuria ≥12 h (stage 3), RRT initiated Yes → stage 3 → Result: AKIN stage 3（ΔCr: 0.45 mg/dL, Ratio: 1.57×, Cr stage: 1）
