What is the normal range for White Blood Cell (WBC) count?

The normal range for White Blood Cell (WBC) count is typically between 5,000 and 11,000 cells per microliter of blood. This range is established based on healthy adult populations, and it reflects the body’s ability to fight infections and respond to various health conditions. When the WBC count falls within this range, it indicates that the individual's immune system is functioning properly.

Counts below this range may suggest issues such as leukopenia, which can result from certain medical conditions, medications, or autoimmune disorders. Conversely, counts above this range can indicate leukocytosis, which often occurs in response to infection, inflammation, stress, or other medical conditions. Therefore, understanding the normal WBC count range is crucial for assessing a patient's health status and guiding further diagnostic or therapeutic interventions.
