Estimate kidney function from creatinine, age and sex.
Educational estimate only — not a diagnosis. Values are calculated in your browser and never stored. Discuss your results with a licensed clinician.
Frequently asked questions
What does eGFR tell me?
It estimates how well your kidneys filter blood. Higher is generally better; a single value isn't a diagnosis — kidney health is judged over time.
Why is race not used?
The 2021 CKD-EPI equation is race-free, following current guidance to make estimates fairer and more consistent.
