EAL-KDOQI (CKD) Abbreviations and Acronyms (2020)
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.

| CKD 1-5D | All stages of CKD, including those on dialysis |
| CKD 3-5D | Stages 3-5 of CKD, including those on dialysis |
| CKD 5D | Stage 5 CKD, including those on dialysis |

| MHD | End stage CKD, on maintenance hemodialysis |
| Non-dialyzed | All stages of CKD, not on dialysis |
| PD | End stage CKD, on peritoneal dialysis |
| Post-transplant | CKD, post-kidney transplant |
