GFR (Glomerular Filtration Rate) is calculated using the formula: GFR = (140 - age) × (weight in kg) × (0.85 if female) / (72 × serum creatinine in mg/dL). This formula is known as the Cockcroft-Gault equation. It is crucial for evaluating kidney function.

FAQs & Answers

  1. What is GFR and why is it important? GFR, or Glomerular Filtration Rate, is crucial for assessing kidney function and detecting renal impairment.
  2. How often should GFR be tested? It is recommended to test GFR annually for individuals at risk of kidney disease, but consult with a healthcare provider for personalized advice.
  3. What factors can affect GFR results? Factors include age, weight, serum creatinine levels, and whether the individual is male or female.
