What is the Most Accurate Test for GFR? A Comprehensive Guide
Discover the most accurate GFR test and what you need to know about kidney function assessments.

The most accurate test for GFR (Glomerular Filtration Rate) is the inulin clearance test. However, due to its complexity and cost, it is rarely used in clinical practice. Creatinine-based tests, particularly the eGFR (estimated GFR), are more commonly utilized and offer a good balance of accuracy, convenience, and cost-effectiveness.
FAQs & Answers
- What are the types of tests for measuring GFR? The main tests for measuring GFR include the inulin clearance test and creatinine-based tests such as estimated GFR (eGFR).
- Why is the inulin clearance test rarely used? The inulin clearance test is highly accurate but is complex and costly, making it less viable for routine clinical use compared to other tests.
- How is eGFR calculated? eGFR is calculated using serum creatinine levels along with other factors like age, gender, and race to estimate kidney function.
- What does GFR indicate about kidney function? GFR indicates how well the kidneys are filtering blood; a lower GFR can signify impaired kidney function.
