Stages of Chronic Kidney Disease
Chronic Kidney Disease (CKD) often progresses slowly over a period of years. The National Kidney Foundation created a guideline to help physicians identify each level of kidney disease. Glomerular Filtration Rate (GFR) measures kidney function. CKD was divided into five stages to help guide treatment:

Stage GFR
Stage 1  With normal or high GFR (GFR > 90 mL/min)
Stage 2  Mild CKD (GFR = 60-89 mL/min)
Stage 3A  Moderate CKD (GFR = 45-59 mL/min)
Stage 3B  Moderate CKD (GFR = 30-44 mL/min)
Stage 4  Severe CKD 9GFR = 15-29 mL/min)
Stage 5  End Stage CKD (GFR <15 mL/min)


Population Abbreviations
The following stages are used throughout the Chronic Kidney Disease (CKD) guideline and systematic review.
