Calculator Description
Enter Age, Gender and Serum creatinine (mg/dL) to review e gfr with this tool. The estimate is indexed to 1.73 square meters of body surface area.
Estimate glomerular filtration using the adult creatinine equation stated on the page. Compare the output unit with the unit shown on a laboratory report.
The estimate is indexed to 1.73 square meters of body surface area. It differs from an absolute filtration volume or a Cockcroft–Gault clearance estimate.

Frequently Asked Questions
What information do I need for the Kidney Function (eGFR) Calculator?
Prepare Age, Gender and Serum creatinine (mg/dL). Use the correct serum-creatinine unit and age, and verify that an adult equation is appropriate for the intended comparison.
Is eGFR the same as a measured filtration rate?
The estimate is indexed to 1.73 square meters of body surface area. It differs from an absolute filtration volume or a Cockcroft–Gault clearance estimate. A single creatinine-based estimate does not diagnose chronic kidney disease. Equation suitability, trends, urine tests and clinical circumstances need professional interpretation.
How can I check the kidney function (egfr) calculator with an example?
Use the full settings in the worked-example table. They produce e GFR: 76.0. Compare the method and units as well as the displayed number.
Which assumptions apply to this kidney function (egfr) calculator?
Race-free adult creatinine equation; SCr is mg/dL and output is mL/min/1.73 m². A single result does not diagnose chronic kidney disease. Clinical interpretation, urine tests and equation suitability matter. Use the correct serum-creatinine unit and age, and verify that an adult equation is appropriate for the intended comparison.
When should I verify the kidney function (egfr) calculator result elsewhere?
A single creatinine-based estimate does not diagnose chronic kidney disease. Equation suitability, trends, urine tests and clinical circumstances need professional interpretation. For personal care, discuss the measurements and method with a qualified clinician.

How to Use This Calculator
- Use the correct serum-creatinine unit and age, and verify that an adult equation is appropriate for the intended comparison.
- Fill in Age, Gender and Serum creatinine (mg/dL). Use the field units rather than copying an unlabeled value.
- For a result check, reproduce the example beginning with Age = 45 and Gender = Male; copy the remaining settings from the detailed guide.
- Use the page's Calculate or Convert control, or read the updated result where the tool recalculates automatically. Locate e GFR and any supporting breakdown.
- Interpret the result with this distinction in mind: The estimate is indexed to 1.73 square meters of body surface area. Keep the selected inputs alongside the output when comparing scenarios.
Practical example and result check
Worked kidney function (egfr) calculator example. Set Age = 45; Gender = Male; Serum creatinine (mg/dL) = 1.2. The corresponding output is e GFR: 76.0. The estimate is indexed to 1.73 square meters of body surface area.
Before relying on the result
- Confirm the units, dates, rates and time periods entered.
- Review which costs, measurements or assumptions are included and excluded.
- Change one important input at a time to understand the result sensitivity.

Follow the calculation
Relationship used for this example: 2021 CKD-EPI: eGFR = 142 × min(SCr/k,1)^a × max(SCr/k,1)^−1.200 × 0.9938^Age × (1.012 if female). Female k=0.7,a=−0.241; male k=0.9,a=−0.302.
The estimate is indexed to 1.73 square meters of body surface area. It differs from an absolute filtration volume or a Cockcroft–Gault clearance estimate.
Assumptions for this model: Race-free adult creatinine equation; SCr is mg/dL and output is mL/min/1.73 m². A single result does not diagnose chronic kidney disease. Clinical interpretation, urine tests and equation suitability matter.

Apply the result to your own scenario
Replace the illustrative age value (45) with your own value, then complete the other inputs for the same scenario. Use the correct serum-creatinine unit and age, and verify that an adult equation is appropriate for the intended comparison.
