What is the typical normal range for white blood cell counts?

1. 5,000-7,000

2. 8,000-12,000

3. 6,000-10,000

4. 9,700-10,300

The correct answer is: 6,000-10,000

The typical normal range for white blood cell (WBC) counts is generally accepted to be between 4,500 and 11,000 white blood cells per microliter of blood. The selected range of 6,000 to 10,000 falls within this accepted normal range, reflecting a balance of health where the immune system is functioning optimally without indicating any infection or disease. A range that is too narrow or too high may not adequately capture all healthy individuals, as variations can occur based on age, sex, time of day, and individual health status. This particular range is often used in clinical settings as it encompasses the average WBC count for adults, allowing practitioners to assess immune function effectively. In clinical practice, understanding this range and the potential implications of deviations is crucial for diagnosis and treatment planning.
