What is a Normal Kidney Function Marker? Understanding GFR and Kidney Health

Learn about the normal kidney function marker, Glomerular Filtration Rate (GFR), and what a healthy GFR level means for kidney health.

99 views

Glomerular filtration rate (GFR) is a vital marker for normal kidney function, providing an estimate of how well your kidneys are cleaning your blood. A GFR over 90 ml/min is generally considered normal, indicating healthy kidney function. Lower values may suggest kidney disease, urging further evaluation and management by healthcare professionals.

FAQs & Answers

  1. What does a normal GFR mean? A normal GFR, typically over 90 ml/min, indicates that the kidneys are effectively filtering waste from the blood, reflecting healthy kidney function.
  2. What causes a low GFR? A low GFR may be caused by kidney disease, damage, or impaired kidney function, and it requires further medical evaluation to determine the underlying cause.
  3. How is GFR measured? GFR is usually estimated based on blood tests measuring creatinine levels, age, gender, and body size to assess kidney filtration efficiency.
