GFR Calculator: Core Features and Principles

The Glomerular Filtration Rate (GFR) is a key indicator for evaluating kidney function. Based on the CKD-EPI formula, this tool quickly calculates your GFR using parameters like age, gender, and serum creatinine levels, helping users screen for chronic kidney disease (CKD) risks.

Why Choose Our GFR Calculator?

Uses the internationally recognized CKD-EPI formula for accurate and reliable results.
Supports batch data input, ideal for rapid screening of multiple patients in medical institutions.
No software installation required—use it online instantly for free.

How to Use

Enter your age (years), select your gender (male/female), and input your serum creatinine level (μmol/L).
Click the "Calculate" button to automatically generate your GFR value (mL/min/1.73m²).
View the results and refer to clinical staging standards (e.g., GFR ≥ 90 is normal, 60-89 indicates a mild decrease).

Frequently Asked Questions (FAQ)

Why do I need to calculate GFR? — GFR is the core metric for diagnosing and staging chronic kidney disease. Early screening can prevent the condition from worsening.
Is this calculator suitable for children? — This tool is based on the adult CKD-EPI formula. Children require specific pediatric formulas for accurate calculation.

Important Notes

Serum creatinine values must be based on standardized testing. The calculated results are for reference only and do not constitute a clinical diagnosis. Batch processing supports a maximum of 50 records per run. All calculations are performed locally on your device, ensuring no private user data is stored.

Technical Notes & Usage Tips

It is recommended to comprehensively evaluate kidney function in conjunction with other indicators such as urine protein and blood pressure. For populations of African descent, the calculated result should be multiplied by a correction factor of 1.159. Typical input example: 35-year-old male, creatinine 88 μmol/L → GFR ≈ 102 mL/min/1.73m².
