Enhanced GFR Calculator
Calculate your eGFR using the CKD-EPI equation, track trends over time, and monitor your kidney function with comprehensive analysis and personalized insights.
Understanding Your eGFR Results
Your eGFR (estimated Glomerular Filtration Rate) is calculated using the CKD-EPI equation, which is the current standard for kidney function assessment. This equation considers your creatinine level, age, gender, and race to provide the most accurate estimate of your kidney function.
The trend analysis shows how your kidney function is changing over time. A declining trend may indicate kidney disease progression, while a stable or improving trend suggests good management. Regular monitoring helps detect changes early and allows for timely intervention.
Remember that eGFR is an estimate and should be interpreted by healthcare professionals. Your nephrologist can provide comprehensive evaluation and personalized treatment recommendations based on your specific situation.
Monitoring Recommendations
Based on Your Stage
Stage 1-2
Monitor every 6-12 months. Focus on controlling risk factors like diabetes and high blood pressure.
Stage 3
Monitor every 3-6 months. Consider nephrologist consultation and dietary modifications.
Stage 4
Monitor every 1-3 months. Nephrologist care essential. Prepare for kidney replacement therapy.
Stage 5
Immediate nephrologist care required. Kidney replacement therapy (dialysis or transplant) needed.
Lifestyle Recommendations
- Control blood pressure (target <130/80)
- Manage diabetes if present
- Follow a kidney-friendly diet
- Exercise regularly
- Avoid NSAIDs and other kidney-damaging medications
Frequently Asked Questions
What is eGFR and why is it important?
eGFR (estimated Glomerular Filtration Rate) measures how well your kidneys filter waste from your blood. It's the most important indicator of kidney function and helps determine your CKD stage. Regular monitoring helps track kidney health over time.
How accurate is the CKD-EPI equation?
The CKD-EPI equation is the current standard for eGFR calculation and is more accurate than older equations like MDRD. It's validated in large populations and used by most laboratories worldwide. However, it's still an estimate and should be interpreted by healthcare professionals.
What does the trend analysis tell me?
Trend analysis shows how your kidney function is changing over time. A declining trend may indicate kidney disease progression, while a stable or improving trend suggests good management. The rate of change helps predict future kidney function.
When should I be concerned about my eGFR?
Be concerned if your eGFR is below 60, declining rapidly, or if you have symptoms like fatigue, swelling, or changes in urination. Consult a nephrologist for eGFR below 60 or any concerning trends.
