Frequently asked questions
- What is eGFR?
- Estimated glomerular filtration rate (eGFR) measures how well your kidneys filter waste from blood, expressed as mL/min/1.73 m². Normal is ≥90 for most adults.
- What changed in CKD-EPI 2021?
- The 2021 update removed the race coefficient that was present in the 2009 equation, following evidence that race is a social construct rather than a biological variable for this purpose.
- When should I see a nephrologist?
- Referral thresholds vary, but eGFR <30 (G4) generally warrants specialist review. Always discuss your results with your GP or physician.
