What is the typical range for GFR indicating normal renal function?

  1. 40-70 mL/min

  2. 60-90 mL/min

  3. 90-120 mL/min

  4. 120-150 mL/min

The correct answer is: 90-120 mL/min

The typical range for glomerular filtration rate (GFR) indicating normal renal function is between 90-120 mL/min. This range reflects the capacity of the kidneys to filter blood effectively, removing waste products and maintaining fluid and electrolyte balance. A GFR of 90 mL/min is the lower limit of normal, while a GFR reaching 120 mL/min is considered optimal renal function for most healthy adults. Values within this range suggest that the kidneys are functioning properly, providing assurance that they can adequately filter blood and prevent the accumulation of harmful substances in the body. When evaluating renal function, it is important to keep in mind that GFR can vary based on age, sex, and body size, but the standard reference range for a normal GFR remains 90-120 mL/min. So, identifying this range is crucial for healthcare professionals in assessing and managing patients with potential kidney issues.
