Your Glomerular Filtration Rate (GFR) is a crucial indicator of kidney health, showing how well your kidneys filter blood. It varies by age, gender, and body size. Generally, a GFR over 90 mL/min/1.73 m^2 is considered normal for healthy individuals. It may decrease naturally with age. For accurate assessment tailored to your age, consult a healthcare provider who can interpret GFR in the context of your overall health and potential kidney issues.

FAQs & Answers

  1. What is a normal GFR for healthy adults? A normal Glomerular Filtration Rate (GFR) for healthy adults is typically above 90 mL/min/1.73 m², though it can vary depending on age, gender, and body size.
  2. Why does GFR decrease with age? GFR naturally decreases as a part of the aging process because kidney function gradually declines over time, even in the absence of kidney disease.
  3. How is GFR measured and interpreted? GFR is estimated using blood tests measuring creatinine levels, and its interpretation considers factors like age, gender, and overall health. Always consult a healthcare provider for accurate assessment.
