What This Calculator Does
Estimate eGFR using CKD-EPI 2021 creatinine equation.
It combines Sex, Age, Serum Creatinine to estimate Estimated eGFR.
Formula & Method
Core equations: CKD-EPI 2021 creatinine eGFR: eGFR=142\cdot\min(Scr/\kappa,1)^{\alpha}\cdot\max(Scr/\kappa,1)^{-1.200}\cdot0.9938^{Age}\cdot(1.012\,\text{if female}).
Notation used in the formulas: R = Estimated eGFR; x_{1} = Sex; x_{2} = Age; x_{3} = Serum Creatinine.
Method summary: inputs are normalized to consistent units, core equations are evaluated, then secondary values are derived and rounded for display.
Use this calculator for quick scenario analysis. Start with baseline values, change one driver at a time, and compare how sensitive the results are to each input shown above.
Inputs Used
- Sex: Used directly in the calculation.
- Age: Used directly in the calculation.
- Serum Creatinine: Used directly in the calculation.
