Kidney Function Tests Decoded!
Published: Jul 12, 2024
Ever wondered what those kidney function tests really mean? Let's break down the basics of eGFR and why it's important.

What is eGFR?
Estimated Glomerular Filtration Rate (eGFR) is a test that helps measure how well your kidneys are filtering blood. It's calculated using blood levels of markers like creatinine and cystatin C. A healthy eGFR typically ranges from 90 to 120 mL/min, indicating good kidney function.
Why eGFR Matters
eGFR is crucial in detecting kidney disease early before symptoms appear. It helps doctors monitor kidney function over time and determine if treatment is working. Lower eGFR values suggest decreased kidney function and may require further investigation or intervention.
Limitations of eGFR
While eGFR is a useful tool, it's not perfect and may be influenced by factors like age, race, and muscle mass. It's important to consider these factors when interpreting results. When in doubt, additional tests or confirmatory measures may be needed for accurate assessment.
