Formula and methodology
Formula: eGFR = 142 x min(Scr/k,1)^a x max(Scr/k,1)^-1.200 x 0.9938^Age x sex factor, using the 2021 CKD-EPI creatinine constants.
The race coefficient used in older equations is not included.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Age — minimum 18; maximum 120
- Sex coefficient — 2 choices
- Serum creatinine — mg/dL; minimum 0.1; maximum 20
Worked example
| Input | Value |
|---|---|
| Age | 50 |
| Sex coefficient | male |
| Serum creatinine | 1 |
The calculator reports estimated mL/min/1.73 m^2 with the 2021 creatinine equation.
Assumptions and limits
- Stable adult serum creatinine and the units expected by the equation.
- Pregnancy, rapidly changing kidney function, and unusual body composition require clinical interpretation.
