KidneyTracker.com provides educational health tools only. It is not a substitute for professional medical advice, diagnosis, or treatment.

Educational Purpose Only

All tools, calculators, and content on KidneyTracker.com are provided for educational and informational purposes only. They are designed to help you understand your kidney health and have better-informed conversations with your healthcare provider.

Our tools do not:

  • Provide medical diagnoses
  • Replace the advice of a qualified healthcare professional
  • Constitute a doctor-patient relationship
  • Account for your complete medical history and individual circumstances

Calculations and Estimates

Our eGFR Calculator uses the CKD-EPI 2021 equation as recommended by the National Kidney Foundation and KDIGO. While this is the current gold standard for eGFR estimation, results are estimates and may not reflect your actual kidney function. Factors that can affect accuracy include:

  • Extreme body sizes (very small or very muscular individuals)
  • Unusual dietary habits (very high or very low protein)
  • Muscle-wasting conditions
  • Pregnancy
  • Certain medications that affect creatinine levels

Food and Nutrition Data

Nutritional information in our Food Search and Meal Planner tools is sourced from the USDA FoodData Central database and National Kidney Foundation guidelines. Values are approximate and may vary based on preparation method, brand, and growing conditions. Always consult a registered dietitian for a personalized kidney diet plan.

Medication Information

Our Medication Safety Checker provides general information about kidney safety of common medications. This information:

  • Is based on National Kidney Foundation and FDA guidelines
  • Does NOT replace a pharmacist's or physician's assessment
  • May not account for drug interactions specific to your medication regimen
  • Never stop or change a medication without consulting your healthcare provider

Symptom Information

The Kidney Symptom Checker provides general information about symptoms that may be kidney-related. It does NOT diagnose any condition. If you are experiencing concerning symptoms, contact your healthcare provider.

If you experience a medical emergency — including blood in urine, inability to urinate, severe pain, or difficulty breathing — call 911 immediately.
