Researchers led by Ibrahim Hashim, PhD, analyzed serum creatinine values of 56,676 patients over 16 months, according to a July 26 news release. After removing the race adjustment, 14% to 28% of Black patients were moved to a more severe kidney disease classification.

UT Southwestern began using a new race modifier-free formula in May, according to the news release.
