What is the normal WBC count range for adults?

The normal white blood cell (WBC) count range for adults is 4,500 to 11,000 cells per microliter of blood, which aligns most closely with the choice indicating a range of 5,000 to 10,000. This range is important in the medical field as it helps healthcare professionals assess a person’s immune response and identify potential health issues.

A count below the normal range can indicate conditions such as infections, bone marrow problems, or autoimmune disorders, while a count above the normal range, as seen in other options, could suggest an infection, inflammation, or hematological disorders. Understanding these values is crucial for diagnosing and managing various medical conditions effectively. The chosen range reflects accepted clinical standards and provides a reliable reference point for evaluating WBC counts in a healthy adult population.
