Yes, GFR (Glomerular Filtration Rate) can be over 100. A GFR over 100 is typically observed in children and young adults. In such cases, it's generally considered normal and not a cause for concern. However, if you're an adult with a GFR significantly above 100, it might be worth consulting a healthcare professional to ensure it's an indicator of good kidney health rather than an outlier.

FAQs & Answers

  1. What is a normal GFR level? A normal Glomerular Filtration Rate (GFR) is typically between 90 and 120 mL/min for adults. Values may vary based on age, sex, and body size.
  2. What does a high GFR indicate? A high GFR, especially over 100, is often normal in children and may indicate efficient kidney function. However, in adults, it could warrant further investigation to rule out any underlying health issues.
  3. Can a high GFR be dangerous? In most cases, a high GFR is not dangerous, particularly if it is a typical value for your age group. However, consistently elevated GFR levels in adults may require medical evaluation.
  4. How can I improve my GFR? To support healthy GFR levels, maintain a balanced diet, stay hydrated, exercise regularly, manage your blood pressure, and avoid harmful substances that can impact kidney function.
