New Creatinine- and Cystatin C–Based Equations to Estimate GFR without Race

The glomerular filtration rate (GFR) is generally estimated from serum concentrations of endogenous filtration markers such as creatinine or cystatin C. During the past two decades, automated clinical laboratory reporting of GFR estimated with the use of creatinine (eGFRcr) has become widespread,…
