Kidney Disease: Improving Global Outcomes staging for acute kidney injury^*4

Stage	sCr	UO
1	1.5–1.9 times baseline or ≥0.3 μg/dL increase	<0.5 mL/kg/hour for 6 hour
2	2–2.9 times baseline	<0.5 mL/kg/hour for 12 hour
3	3 times baseline. Increase in sCr to ≥4 μg/dL or initiation of RRT	<0.3 mL/kg/hour for 24 hours or anuria for ≥12 hour

^*Acute kidney injury defined as sCr ≥0.3 μg/dL increase in 48 hour or >50% within 7 days
