Learn why GFR might not always be accurate and what factors influence kidney function assessments.

231 views

GFR (Glomerular Filtration Rate) is an important measure of kidney function but it's not always perfectly accurate. Factors like muscle mass, diet, and certain medications can affect the results. For precise assessment, additional tests such as 24-hour urine collection and imaging studies may be needed. Regular monitoring and consultation with healthcare providers ensure the most accurate understanding of kidney health.

FAQs & Answers

  1. What is GFR and why is it important? GFR, or Glomerular Filtration Rate, measures how well your kidneys filter waste from the blood, which is crucial for identifying kidney health.
  2. What factors can affect GFR results? Factors include muscle mass, diet, hydration levels, and medications that may impact the accuracy of the GFR test.
  3. How can GFR be accurately measured? Accurate GFR measurement may require additional tests, such as a 24-hour urine collection and imaging studies.
  4. Why is regular monitoring of kidney function necessary? Regular monitoring helps detect changes in kidney function early, allowing for timely intervention and management.
