What is the normal white blood cell (WBC) count in mm3?

The normal white blood cell (WBC) count for adults typically ranges from 5,000 to 10,000 cells per cubic millimeter (mm³) of blood. This range is important for assessing an individual's immune response and overall health. A count within this range indicates a balanced immune function, while counts outside this range can suggest various health issues, such as infection, inflammation, or bone marrow problems.

Understanding this range helps clinicians make informed decisions about further evaluations and interventions if a patient's WBC count deviates from the norm. Thus, the correct choice reflects the established reference values used in clinical practice to assess patients effectively.
