eGFR
An estimate of kidney filtering power.

eGFR is an estimated filtration rate calculated from creatinine, age and sex. Below 60 mL/min/1.73 m² for more than 3 months suggests chronic kidney disease.
| Stage | eGFR (mL/min/1.73 m²) |
|---|---|
| G1 | ≥90 |
| G2 | 60–89 |
| G3a | 45–59 |
| G3b | 30–44 |
| G4 | 15–29 |
| G5 | <15 |
