Pediatric eGFR Calculator
Uses the bedside Schwartz equation for children and CKD-EPI 2021 for adults.
The calculator selects CKD-EPI for ages ≥ 18 years and the bedside Schwartz equation for ages < 18 years. For pediatric patients, provide accurate height and weight to support the calculation and body surface area estimation.
Use chronological age in completed years (decimals allowed for infants).
Values entered in µmol/L are converted automatically (1 mg/dL = 88.4 µmol/L).
Required for pediatric patients; optional for adults (also supports BSA estimation).
Required for pediatric patients; used to auto-calculate body surface area when available.
Optional: Provide measured or estimated BSA to de-index the eGFR.

CKD GFR Categories (KDIGO 2024)
| Category | eGFR (mL/min/1.73 m²) | Interpretation |
|---|---|---|
| G1 | ≥ 90 | Normal or high (consider other markers of kidney damage) |
| G2 | 60–89 | Mildly decreased (requires markers of kidney damage for CKD diagnosis) |
| G3a | 45–59 | Mildly to moderately decreased |
| G3b | 30–44 | Moderately to severely decreased |
| G4 | 15–29 | Severely decreased |
| G5 | < 15 | Kidney failure |
