How to Use This Calculator
- Enter serum creatinine (mg/dL), patient age (years), and body weight (kg).
- Select biological sex (0 = male, 1 = female).
- Read eGFR using the 2021 CKD-EPI race-free equation (mL/min/1.73m2).
- Review creatinine clearance via Cockcroft-Gault (mL/min) for drug dosing decisions.
- Note the resulting CKD stage (1-5) based on the calculated eGFR.
