Furosemide Stress Test (AKI Progression)
Furosemide stress test (Chawla 2013): 1.0 mg/kg (loop-naive) or 1.5 mg/kg (prior loop) IV furosemide; a 2-hour urine output ≤ 200 mL predicts progression to stage 3 AKI.

Example
- Weight
- 70 kg
- 2-hour urine output
- 150 mL
- Prior loop-diuretic exposure
- No
Result: Furosemide stress test: 1.0 mg/kg = 70 mg IV; 2-hour urine 150 mL <= 200 predicts progression to stage 3 AKI.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Passes
- 2-hour urine output > 200 mL: progression to stage 3 AKI less likely.
- Progression
- 2-hour output <= 200 mL predicts progression to KDIGO stage 3 AKI. A risk test, not a diuretic order.
What you enter
- Weight
- 2-hour urine output
- Prior loop-diuretic exposure (uses 1.5 mg/kg dose)
