eGFR staging alone does not diagnose or exclude kidney disease without repeat testing, urine albumin and clinical assessment.

Test how a different creatinine value changes eGFR without changing your main result.
Calculate your baseline first
It uses the 2021 CKD-EPI creatinine equation, which estimates glomerular filtration rate from serum creatinine, age and sex without a race coefficient.
This tool shows KDIGO G categories: G1 ≥90, G2 60–89, G3a 45–59, G3b 30–44, G4 15–29 and G5 <15 mL/min/1.73m².
No. A single eGFR is a screening and staging aid. Diagnosis usually requires persistence over time, urine albumin, urinalysis, imaging or other clinical information interpreted by a qualified clinician.
Results are estimates generated locally in your browser using the 2021 CKD-EPI creatinine equation. This tool is for informational and educational purposes only, not medical advice, diagnosis, triage or treatment guidance. Creatinine-based eGFR can be inaccurate in unusual muscle mass, acute kidney injury, pregnancy, dialysis, extremes of diet or rapidly changing kidney function.
