The estimated glomerular filtration rate (eGFR) measures how slowly or quickly kidneys remove a waste product called creatinine from the blood. The eGFR calculation helps doctors understand how sick a kidney patient is. For a number of years, some eGFR calculations included a modifier for patients identified as Black. This practice led to a systemic underestimation of how sick some Black patients really were. In some cases, it meant Black patients had to wait longer to be listed for kidney transplants. In other cases, it delayed when Black candidates qualified to start gaining waiting time, a major factor in the priority that kidney candidates receive. Learn more about race and eGFR.
Removing race variables from eGFR is broadly supported by the National Academies of Sciences, Engineering and Medicine (NASEM), a joint task force of the American Society of Nephrology, and the National Kidney Foundation.
