An elevated white blood cell count, also known as leukocytosis, is commonly associated with infection or inflammation. When the body encounters pathogens such as bacteria, viruses, or other foreign substances, the immune system responds by producing more white blood cells. This response is a crucial part of the body’s defense mechanism, as these cells are responsible for identifying and neutralizing the threat to maintain health.

In the context of infection, white blood cells are mobilized to the site of the infection, leading to a measurable increase in their count in the bloodstream. Similarly, in cases of inflammation, whether caused by autoimmune diseases or physical injury, the body may produce more white blood cells as part of the inflammatory response. This makes infection or inflammation the most common reasons for an elevated white blood cell count compared to other potential reasons like anemia or dehydration.
