Creatinine clearance is widely regarded as a reliable marker for GFR (glomerular filtration rate). It measures how well kidneys filter waste from the blood, providing essential insights into kidney health. For more precise assessment, Cystatin C can also be used, especially in individuals where creatinine levels may be influenced by other factors.

FAQs & Answers

  1. What is GFR and why is it important? GFR, or glomerular filtration rate, indicates how well your kidneys are filtering blood, essential for understanding kidney function.
  2. How is creatinine clearance measured? Creatinine clearance is measured through a urine test that determines how much creatinine is being filtered by the kidneys.
  3. When should Cystatin C be used instead of creatinine? Cystatin C is preferred in individuals with varying muscle mass or kidney conditions that affect creatinine levels, providing a more accurate assessment.
  4. What factors can affect GFR readings? Factors such as dehydration, medications, and muscle mass can influence GFR readings, making accurate assessment essential.
