Glomerular filtration rate

eGFR estimate by the CKD-EPI 2021 formula (race-free) — chronic kidney disease staging

Glomerular filtration rate

eGFR

mL/min/1.73 m²

99

G1 — normal or high

CKD-EPI 2021 for adults ≥18. CKD is diagnosed when eGFR <60 persists ≥3 months or with other kidney damage markers. Estimate only.

CKD stages (KDIGO)

  • ≥90 — G1 — normal or high
  • 60–89 — G2 — mildly decreased
  • 45–59 — G3a — moderately decreased
  • 30–44 — G3b — moderately-severely decreased
  • 15–29 — G4 — severely decreased
  • <15 — G5 — kidney failure
