What is the Best Marker for Measuring GFR?

Discover why inulin is considered the ideal marker for GFR and its implications for assessing kidney function.

The ideal marker for GFR (Glomerular Filtration Rate) is inulin because it is freely filtered by the glomeruli and neither reabsorbed nor secreted by kidney tubules. This makes it highly accurate for measuring kidney function.

FAQs & Answers

  1. What is Glomerular Filtration Rate (GFR)? GFR is a test used to measure how well your kidneys filter blood, providing an estimate of kidney function.
  2. Why is inulin used as a GFR marker? Inulin is used as it is freely filtered by the kidneys and is not reabsorbed or secreted, making it accurate for GFR measurement.
  3. What are the implications of low GFR? A low GFR indicates impaired kidney function, which may require medical attention or intervention.
