GFR Calculator — eGFR Calc

Estimate glomerular filtration rate (eGFR) using CKD-EPI 2009 or MDRD (4-variable). Results are for informational use only — see disclaimer below.

CKD-EPI typically preferred for adults. Choose creatinine units, enter age & sex. Results are estimated; clinical interpretation should be by a clinician with full context.
Disclaimer: Results are approximations from formulas (CKD-EPI or MDRD). Not a substitute for professional medical assessment. For personalized interpretation, contact a clinician or nephrologist.
