2021 CKD-EPI Equations for Glomerular Filtration Rate (GFR)
Estimates GFR using age, sex, and serum creatinine, with an optional cystatin C input to calculate the combined equation without a race multiplier.
INSTRUCTIONS
Use this calculator to estimate kidney function. Enter age, sex, and serum creatinine for the standard estimate. If available, add serum cystatin C to automatically calculate the more precise combined equation.
