Calculate estimated glomerular filtration rate (eGFR) and creatinine clearance.
Required for Cockcroft-Gault calculation
This calculator is a reference tool. eGFR should be interpreted in clinical context. Consult KDIGO guidelines for CKD management.
| Stage | eGFR (mL/min/1.73m²) | Description |
|---|---|---|
| G1 | ≥90 | Normal or high |
| G2 | 60-89 | Mildly decreased |
| G3a | 45-59 | Mildly to moderately decreased |
| G3b | 30-44 | Moderately to severely decreased |
| G4 | 15-29 | Severely decreased |
| G5 | <15 | Kidney failure |
