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)
