Staging of Kidney Failure
The National Kidney Foundation has adopted a stratification of patients with renal failure into the following 5 stages based on the glomerular filtration rate (GFR):
- Stage 1: Kidney damage with normal or elevated GFR (> or = 90 mL/min)
- Stage 2: Kidney damage with mild decrease in GFR (60-89 mL/min)
- Stage 3: Moderate decrease in GFR (30-59 mL/min)
- Stage 4: Severe decrease in GFR (15-29 mL/min)
- Stage 5: Kidney Failure (GFR < 15 mL/min or those on dialysis)
