What is the normal white blood cell count range?

• A. 3,000-9,000
• B. 8,000-14,000
• C. 4,000-11,000
• D. 6,000-12,000

Answer: (C)

Normal white blood cell count is typically 4,000 to 11,000 cells per microliter of blood. This range comes from standard CBC reference values for adults. A count within this range indicates a normal immune cell level. Values above can suggest infection, inflammation, stress, or hematologic conditions, while values below may indicate bone marrow suppression or leukopenia. The range 4,000-11,000 matches the common adult reference, making it the best choice. The other ranges fall outside the typical adult normal range and would not be considered normal.
