Fever in children when it comes to the hospital, doctors sometimes write a test form, so that child check white blood cells in the blood. Children with fever why check white blood cells in the blood at all?
Because white blood cells are the body\'s major defense systems, various pathogenic micro-organisms invade the human body, white blood cells in the blood will be actively involved in the fighting, when the number of white cells in the blood will change. Therefore, check changes of white blood cells in the blood are important means of diagnosing disease.
White cells is not a single form of cell. Based on morphology and function of different white blood cells can be divided into polymorphonuclear cells, Eosinophilic granulocytes, Basophilic granulocytes, lymphocytes and mononuclear cells in five. Neutrophil and monocyte phagocytosis has a very strong, they can devour the bacteria and other microorganisms. Lymphocytes can also produce antibodies and other methods on the intrusion of foreign bodies play a role in the body. Eosinophilic cells is associated with human reactions to parasite. In short, the specific effect of different white blood cells are different, but the main direction of effect is consistent, invades foreign bodies is eliminated.
Different pathogenic microbes invade the human body, number of white cells in the blood will change. Such as acute bacterial infections often cause increased neutrophil percentage and total number of white blood cell increase in virus infected lymphocytes is increasing, sometimes appear abnormal lymphocytes, and no obvious increase or reduce the total number of white cells.
