National Kidney Foundation (NKF) Guideline for Chronic Kidney Disease (CKD)with GFR Stages: 

G1: ≥ 90  - NORMAL OR HIGH 
G2: 60-89 - MILDLY DECREASED 
G3a: 45-59 - MILDLY TO MODERATELY DECREASED 
G3b: 30-44 - MODERATELY TO SEVERELY DECREASED 
G4: 15-29 - SEVERELY DECREASED 
G5: <15   - KIDNEY FAILURE 

Abnormalities present for at least 3 months discriminate between chronic and acute disease. 

 

Estimated GFR is calculated using the CKD-EPI equation.
