Why was race removed from the CKD-EPI 2021 equation?

The race coefficient in the 2009 equation overestimated GFR in Black patients, potentially delaying CKD recognition and referral. The 2021 race-free equation provides equivalent or better accuracy across all racial groups.

When is CKD-EPI 2021 preferred over MDRD-4?

CKD-EPI 2021 is preferred for all patients as it is more accurate at GFR >60 mL/min/1.73m², particularly for monitoring early CKD and assessing cardiovascular risk in patients with near-normal kidney function.
