How It Works
The CKD-EPI 2021 equation estimates glomerular filtration rate without using race as a variable. It uses serum creatinine, age, and sex to calculate eGFR. CKD stages range from G1 (normal, >90) through G5 (kidney failure, <15). eGFR is used for CKD staging, drug dosing decisions, and determining when to refer to nephrology.
