Which are an average of WBCs per cubic millimeter of blood?

The average number of white blood cells (WBCs) in a cubic millimeter of blood typically ranges from about 4,000 to 11,000 cells. This count can vary based on factors such as age, health status, and the presence of infections or other medical conditions. WBCs play a crucial role in the immune system, helping to defend the body against infections and diseases. Regular blood tests can help monitor WBC levels for any abnormalities.
