Parameters
Results
- eGFR
- 89 mL/min/1.73m²
- CKD stage
- G2
CKD-EPI 2021 without race adjustment. Does not replace nephrology evaluation.
How it works
Estimate glomerular filtration rate (eGFR) using the CKD-EPI 2021 creatinine equation.
Who it's for: Clinicians and students interpreting kidney function labs — not for self-diagnosis.
Uses serum creatinine (mg/dL), age, and sex without race adjustment.
Stages kidney disease G1–G5 per KDIGO guidelines.
Reference estimate only — does not replace nephrology evaluation.
How to use
- Select Sex, enter Age (years), and Creatinine (mg/dL).
- Read eGFR in mL/min/1.73m² and CKD stage.
Good to know
- Do not adjust medications based solely on this calculator — consult a licensed provider.
