CKD-EPI Equations for Glomerular Filtration Rate (GFR)
This calculator includes inputs based on race, which may or may not provide better estimates, so we have decided to make race optional. See here for more on our approach to addressing race and bias on MDCalc.
For the same creatinine value, this calculator estimates a higher GFR for Black patients.
For use in patients with stable kidney function. While the combined creatinine and cystatin C equation can add accuracy, cystatin c is not available in all laboratories and the creatinine-based equation is adequate for most clinical purposes.
