    Kinetic Estimated Glomerular Filtration Rate (keGFR)

    Estimates GFR in patients with acutely changing creatinine.
    Favorite

    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.

    Advice

    • While estimated GFR (by a validated equation) is adequate for most clinical scenarios, measured GFR is still considered the gold standard.

    • Remember, eGFR is an estimate of kidney function, but is not included in the definition of AKI.
