Is eGFR Accurate in the Elderly? Understanding the Limitations

Explore the accuracy of eGFR in elderly patients and learn about additional assessment methods for better kidney health.

550 views

eGFR (estimated Glomerular Filtration Rate) may not be entirely accurate in the elderly due to factors like reduced muscle mass, variations in serum creatinine, and other age-related changes. For more precise assessment, a healthcare provider may consider additional tests or factors such as cystatin C levels or direct measurement of GFR.

FAQs & Answers

  1. Why is eGFR less reliable in elderly patients? eGFR can be less reliable in the elderly due to factors such as reduced muscle mass and variations in serum creatinine levels.
  2. What alternative methods can assess kidney function in the elderly? Additional assessment methods include measuring cystatin C levels and direct GFR measurement for more accurate evaluation.
  3. How can aging affect kidney function? Aging can result in physiological changes that affect kidney function, making standard markers less reliable.
  4. What is cystatin C and why is it important? Cystatin C is a protein that can be measured to evaluate kidney function and may provide a more accurate assessment than creatinine.
