How to calculate

Apply an entered age/sex-adjusted clinical coefficient to serum creatinine for educational comparison.

Illustrative eGFR = coefficient/creatinine

Worked example

Serum creatinine (mg/dL): 1; Equation coefficient supplied by clinician/lab: 100.

Illustrative eGFR: 100 mL/min/1.73m².

Assumptions and limits

This is deliberately not a diagnostic CKD-EPI calculator. Laboratories use validated equations with age and sex terms; use the reported laboratory eGFR and consult a clinician.

Results are rounded for display; calculations use unrounded values. Read our calculation methodology.

Understanding the result

Apply an entered age/sex-adjusted clinical coefficient to serum creatinine for educational comparison. The displayed figures use the inputs and formula shown on this page.

When this tool is useful

Use the kidney egfr planning to compare a scenario, check an estimate, or verify a manual calculation.

Frequently asked questions

What should I check before using the kidney egfr planning result?

This is deliberately not a diagnostic CKD-EPI calculator. Laboratories use validated equations with age and sex terms; use the reported laboratory eGFR and consult a clinician.

Is this kidney egfr planning result exact?

It is exact for the stated mathematical model and entered values. Real-world results can differ when rates, timing, fees, definitions or measurement conditions differ.
