What laboratory result indicates a healthy level of white blood cells?

A normal white blood cell count reflects a healthy immune system capable of effectively responding to infections and other health issues. The reference range for white blood cell counts typically falls between approximately 4,000 and 11,000 cells per microliter of blood, though this can vary by laboratory and specific patient factors.

When the white blood cell count is within this normal range, it indicates that the body is maintaining an adequate level of immune response without experiencing undue stress from infections, inflammation, or other pathological conditions. Values outside of this range—whether too high or too low—can suggest underlying health problems, such as infections, bone marrow issues, or autoimmune disorders. Therefore, the presence of a normal white blood cell count is a strong indicator of overall health in relation to the immune system.
