    Kinetic Estimated Glomerular Filtration Rate (keGFR)

    Estimates GFR in patients with acutely changing creatinine.

    IMPORTANT

    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.

    INSTRUCTIONS

    Take two serum creatinine measurements (Cr1 and Cr2), at two different time points (time1 and time2). Note: uses MDRD equation for calculating GFR.

    Why Use

    Other equations estimating GFR (Cockcroft-Gault, MDRD) have limited accuracy when creatinine is changing acutely.
