eGFR — Kidney Function (CKD-EPI 2021)

Estimate your kidney function with the 2021 race-free CKD-EPI equation — the standard recommended by kidney societies worldwide.

Awaiting clinical review. Results are based on validated formulas but pending physician verification.

How this is calculated

Uses the 2021 CKD-EPI creatinine equation, which estimates GFR from serum creatinine, age and sex. Race is deliberately not an input — modern guidelines are race-free.
