Kidney Function (eGFR) Calculator
How to use this calculator
Enter your serum creatinine from a standard blood panel, plus your age and sex.
What your result means
This uses the 2021 CKD-EPI creatinine equation, the current race-free version recommended by the National Kidney Foundation and American Society of Nephrology joint task force. Kidney function naturally declines with age, and creatinine alone can look falsely normal in people with lower muscle mass (common in older adults) — eGFR corrects for age and sex to give a clearer picture, reported in stages from G1 (normal) to G5 (kidney failure).
