How often to monitor eGFR in CKD
It depends on the stage (severity) of CKD. These are broad guidelines. eGFR is based on measuring the creatinine level in the blood – the lower the creatinine level, the earlier stage of CKD, the better.
CKD1-2 (eGFR 60-120 ml/min) = Risk factors for CKD. Creatinine – normal (< 120 mcmol/L)
- eGFR/creatinine should be measured every 12 months
CKD3A (eGFR 30-59 ml/min) = Mild CKD. Creatinine – normal or <150 mcmol/L
- eGFR/creatinine every 6 months
CKD3B (eGFR 30-59 ml/min) = Mild CKD (but worse than CKD3A). Creatinine usually 150-200 mcmol/L
- eGFR/creatinine every 4-6 months
- Urinary ACR (uACR) – if monitoring the protein level in the urine is important in your disease – every 6 months
CKD4 (eGFR 15-29 ml/min) = Moderate CKD. Creatinine usually 200-400 mcmol/L
- eGFR/creatinine every 2-4 months
- Urinary ACR, if needed, every 4 months
CKD5 (eGFR <15 ml/min) = Severe CKD (approaching dialysis). Creatinine usually >400 mcmol/L
- eGFR/creatinine every 1-2 months
Note. When on dialysis, and when stable, the frequency of monitoring can go down, to every 6 months.
