Understanding the GFR Formula: What is Glomerular Filtration Rate?

Learn about the GFR formula to assess kidney function and maintain renal health.

90 views

The formula for calculating GFR (glomerular filtration rate) is: GFR = (140 - age) × (weight in kg) × (0.85 if female) / (72 × serum creatinine in mg/dL). This formula, known as the Cockcroft-Gault equation, helps to estimate kidney function and assess renal health.

FAQs & Answers

  1. What does GFR stand for? GFR stands for glomerular filtration rate, a measure of how well your kidneys filter blood.
  2. Why is GFR important? GFR is crucial for assessing kidney function and diagnosing potential renal diseases.
  3. How is GFR calculated? GFR is calculated using the formula: GFR = (140 - age) × (weight in kg) × (0.85 if female) / (72 × serum creatinine in mg/dL).
  4. What does a low GFR indicate? A low GFR may indicate impaired kidney function and the need for further medical evaluation.
