A = 0.7 B = -1.2 |
Scr ≤0.9mg/dL |
Scr >0.9mg/dL |
A = 0.9 B = -0.302 |
A = 0.9 B = -1.2 |
CKD-EPI (Creatinine) was developed by Levey et al. in 2009 and validated by Inker et al. in 2012, found to be more accurate than the MDRD equation. Recent debates about its use in Black patients (race being a social construct rather than a biological one) led Inker et al. to update the CKD-EPI formula in 2021 to remove race from the equation.
