Feedback: Stages of chronic renal failure are based on the glomerular filtration rate (GFR). Stage 3 is defined by a GFR in the range of 30 to 59 mL/min/1.73 m2. This is considered a moderate decrease in GFR. Stage 1 is defined by a GFR > 90 mL/min/1.73 m2. Stage 2 is defined by a GFR of 60 to 89 mL/min/1.73 m2. Stage 4 is a GFR in the range of 15 to 29 mL/min/1.73 m2. Stage 5 is a GFR > 15 mL/min/1.73 m2.
