GFR Calculator - Glomerular Filtration Rate

Calculate your Glomerular Filtration Rate (GFR) to assess kidney function. GFR is a crucial indicator of how well your kidneys are filtering waste from your blood.

Understanding GFR Calculation

The Glomerular Filtration Rate (GFR) is a key indicator of kidney function. It measures how well your kidneys filter waste from your blood. The estimated GFR (eGFR) is calculated using your creatinine level, age, sex, and race.

Why is GFR Important?

Monitoring GFR is crucial for:

• Early Detection of Kidney Disease - Identifying kidney problems before symptoms appear
• Treatment Planning - Adjusting medication dosages based on kidney function
• Disease Progression - Tracking the advancement of chronic kidney disease
• Health Risk Assessment - Evaluating risk for cardiovascular complications

GFR Stages and Interpretation

Our calculator uses the CKD-EPI equation, which is considered the most accurate method for estimating GFR. Results are categorized into stages, from normal (> 90 ml/min/1.73m²) to kidney failure (< 15 ml/min/1.73m²).
