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

The normal range for White Blood Cell (WBC) count is between 5,000 and 11,000 cells per microliter of blood. This range is essential because WBCs play a crucial role in the immune system, helping the body to fight infections and other diseases. Maintaining a WBC count within this range indicates a healthy immune response and overall health, as deviations can signify various medical conditions.

A count below this range may suggest leukopenia, which can be caused by factors such as bone marrow disorders, autoimmune diseases, or the effects of medications. Conversely, a count above this range might indicate leukocytosis, often associated with infections, stress responses, or hematological conditions. Therefore, the understanding of this normal range is important for the assessment of a patient's health status.
