About GFR

Glomerular Filtration Rate (GFR) is an important measure of kidney function. It estimates how much blood is filtered by the kidneys per minute.

How This Calculator Works

This calculator uses the CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) formula, which provides an accurate estimate for adults based on age, gender, and serum creatinine levels.

Health Advice

GFR results are only estimates. Always consult your healthcare provider for proper diagnosis and treatment decisions.

FAQs

What is a normal GFR? Typically above 90 mL/min/1.73m².
Can I calculate GFR at home? This tool gives an estimate, but lab tests are required for accuracy.
Why do units matter? Different countries report creatinine in mg/dL or µmol/L.
