What is the normal range for white blood cell count in adults?

• A. 1,000 to 3,000 cells per microliter of blood
• B. 4,000 to 11,000 cells per microliter of blood
• C. 10,000 to 15,000 cells per microliter of blood
• D. 3,000 to 5,000 cells per microliter of blood

Answer: (B)

The normal range for white blood cell (WBC) count in adults is typically between 4,000 to 11,000 cells per microliter of blood. This range is considered a healthy indicator of the body’s immune function, as white blood cells are crucial for fighting infections and responding to inflammation. A WBC count within this range suggests that the individual has a sufficient number of white blood cells to effectively respond to pathogens. Values below or above this range may indicate various medical conditions; for example, a lower count may suggest issues such as bone marrow disorders or certain infections, while a higher count can be a response to stress, infection, or other underlying health issues. Understanding this normal range is critical for health assessments, as deviations can provide insights into a patient’s overall health status.
