CAMRT Radiography Practice Exam

What is considered a normal GFR (Glomerular Filtration Rate)?

1. 60 to 90

2. 70 to 110

3. 90 to 120

4. 120 to 150

The correct answer is: 90 to 120

The normal range for Glomerular Filtration Rate (GFR) is typically considered to be 90 to 120 mL/min/1.73 m², making this choice the most accurate. GFR is an important measure used to assess kidney function, indicating how well the kidneys are filtering blood and removing waste products. Values within this range suggest that the kidneys are functioning optimally. When interpreting GFR values, it's important to consider that values below 90 may indicate a decline in kidney function, while values significantly above 120 may reflect hyperfiltration, often seen in conditions such as diabetes. Clinicians use GFR as a key parameter for diagnosing and monitoring renal disease, and deviations from the normal range can warrant further investigation or intervention.
