CKD-EPI 2021 eGFR

Inker LA, Eneanya ND, Coresh J, et al. New creatinine- and cystatin C-based equations to estimate GFR without race. This calculator implements the 2021 creatinine-only equation (CKD-EPI 2021).

Endorsed by the NKF–ASN Task Force on Reassessing the Inclusion of Race in Diagnosing Kidney Disease (2021) and adopted in KDIGO CKD guidance. Requires standardised (IDMS-traceable) serum creatinine; eGFR is reported per 1.73 m² and is least reliable near normal function.
