How to Accurately Calculate GFR in Children Using the Schwartz Formula

Learn how to calculate GFR in children with the Schwartz formula for early kidney function assessment.

697 views

To calculate GFR in children, use the Schwartz formula: GFR = (K x height in cm) / serum creatinine in mg/dL. The value of K varies by age and sex - typically 0.33 for full-term infants, 0.45 for children and adolescent girls, and 0.55 for adolescent boys. This formula helps determine kidney function and diagnose any potential renal issues early.

FAQs & Answers

  1. What is GFR and why is it important in children? GFR, or Glomerular Filtration Rate, measures kidney function and is crucial for detecting kidney issues early in children.
  2. Can factors like age and sex affect GFR calculations? Yes, the value of K in the Schwartz formula varies by age and sex, impacting GFR results.
  3. What other methods are used to assess kidney function in children? Other methods include urine tests, imaging, and blood tests that evaluate creatinine levels.
  4. How frequently should GFR be monitored in children with kidney disease? GFR should be monitored regularly, as advised by a pediatric nephrologist, to track kidney function over time.
