Glomerular Filtration Rate (GFR) Calculator
The Glomerular Filtration Rate (GFR) is a crucial indicator of kidney function. It measures how effectively your kidneys are filtering waste products from your blood. A lower GFR can indicate kidney damage or disease. This calculator uses the CKD-EPI creatinine equation, a widely accepted formula for estimating GFR.
What is GFR?
Your kidneys contain millions of tiny filters called glomeruli. These glomeruli filter waste products and excess fluid from your blood, which is then excreted as urine. The GFR represents the volume of fluid filtered by these glomeruli per unit of time. A healthy GFR is typically above 90 mL/min/1.73 m².
Why is GFR Important?
Monitoring your GFR is essential for detecting and managing kidney disease. Early detection allows for interventions that can slow or prevent further kidney damage, potentially avoiding the need for dialysis or a kidney transplant. Factors like diabetes, high blood pressure, and certain medications can affect kidney function and, consequently, your GFR.
The CKD-EPI Equation
The Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation is a common method for estimating GFR. It takes into account serum creatinine levels, age, sex, and race (though race is being removed from newer versions of the equation due to its limited clinical utility and potential for bias).
