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

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.
