About eGFR

eGFR (estimated Glomerular Filtration Rate) is a measure of how well your kidneys are working. It estimates the volume of blood that is filtered by the kidneys per minute.

Normal eGFR: 90 mL/min/1.73m² or higher indicates normal kidney function.

Decreased eGFR: Values below 60 mL/min/1.73m² for 3 months or more may indicate chronic kidney disease.

Important: This calculator is for adults 18 years and older. Always consult with a healthcare provider for proper interpretation of results.

Why Monitor eGFR?

Early Detection: eGFR helps identify kidney problems before symptoms appear.

Disease Progression: Tracks how kidney function changes over time.

Treatment Planning: Guides medication dosages and treatment decisions.

Prevention: Identifies risk factors for kidney disease progression.

Quality of Life: Early intervention can prevent complications and improve outcomes.
