eGFR Calculator
Calculate Estimated Glomerular Filtration Rate (eGFR) using the latest CKD-EPI 2021 race-free equation to accurately assess renal function and stage Chronic Kidney Disease.
Patient Variables
Clinical Precision & Methodology
This calculator utilizes the 2021 CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) equation, which is recommended by the National Kidney Foundation (NKF) and the American Society of Nephrology (ASN). It intentionally removes race coefficients for equitable assessment.
Modern Clinical Standard
Replaces older formulas like Cockcroft-Gault and MDRD. The 2021 CKD-EPI formula is currently the gold standard for staging chronic kidney disease globally.
Race-Free Algorithm
Eliminates the Black/Non-Black racial multiplier found in the 2009 equations, ensuring unbiased diagnostic criteria for renal impairment.
