What is a Good GFR for My Age? Understanding Kidney Function Levels

Learn what Glomerular Filtration Rate (GFR) values indicate healthy kidney function by age and size. Get expert insights for interpreting your GFR results.

8 views

Glomerular Filtration Rate (GFR) is a crucial marker for kidney function, and a good GFR varies by age, sex, and body size. Generally, a GFR of 60 mL/min/1.73 m² or more is considered normal for most adults. However, values above 90 mL/min/1.73 m² are optimal, indicating healthy kidney function. It's important to consult with a healthcare provider for a precise evaluation, as they can interpret your GFR in the context of your specific health profile.

FAQs & Answers

  1. What does a low GFR indicate? A low Glomerular Filtration Rate may indicate impaired kidney function or chronic kidney disease and should be evaluated by a healthcare provider.
  2. How does age affect GFR values? GFR naturally declines with age, so what is considered a normal GFR varies and must be interpreted relative to age, sex, and body size.
  3. Can lifestyle changes improve my GFR? Yes, maintaining a healthy diet, controlling blood pressure, staying hydrated, and avoiding nephrotoxic substances can help improve or maintain your GFR.
  4. How is GFR measured? GFR is estimated through blood tests measuring creatinine levels combined with calculations considering age, sex, and body size.
