eGFR Calculator
Estimated Glomerular Filtration Rate
Your Estimated GFR:
The eGFR calculation uses the CKD-EPI equation. This is an estimate only and should be interpreted by a healthcare professional along with other clinical data. Values may vary based on muscle mass, nutritional status, and other factors.
The eGFR (Estimated Glomerular Filtration Rate) Calculator is a medical tool used to assess kidney function. It helps determine how well the kidneys filter waste from the blood. The result is crucial for diagnosing and monitoring kidney diseases.
What is eGFR?
eGFR is a measure of kidney function based on factors like age, gender, creatinine levels, and sometimes race. A lower eGFR value may indicate reduced kidney function, while a higher value suggests healthy kidneys.
Why is eGFR Important?
Doctors use the eGFR test to:
- Detect kidney disease at an early stage
- Monitor the progression of chronic kidney disease (CKD)
- Adjust medications that depend on kidney function
- Plan treatments such as dialysis or kidney transplant
How is eGFR Calculated?
The eGFR calculation is based on the serum creatinine level in the blood, along with other factors such as:
- Age: Kidney function declines with age
- Gender: Men and women have different muscle mass, affecting creatinine levels
- Serum Creatinine: A waste product that kidneys filter from the blood
- Race (Optional in Some Formulas): Used in some equations for more accuracy
Understanding eGFR Results
The eGFR value is measured in mL/min/1.73m², with the following classifications:
- Above 90: Normal kidney function
- 60-89: Mildly decreased function, may indicate early kidney disease
- 30-59: Moderate kidney disease, medical attention needed
- 15-29: Severe kidney disease, requiring treatment
- Below 15: Kidney failure, dialysis or transplant may be needed
Who Should Use an eGFR Calculator?
An eGFR calculator is beneficial for:
- People with diabetes or high blood pressure: These conditions increase the risk of kidney disease
- Individuals with a family history of kidney disease: Early screening helps in prevention
- Those experiencing kidney-related symptoms: Symptoms like swelling, fatigue, or changes in urination
- Doctors and healthcare providers: To track kidney function over time
Conclusion
The eGFR calculator is a vital tool for estimating kidney function and detecting early signs of kidney disease. Regular kidney function tests help in monitoring health and taking preventive measures. If your eGFR is low, consult a doctor for further evaluation and treatment.
