Leukemia is only one cause of elevated leukocytes, defined as leukocytosis when the peripheral blood leukocyte count is consistently higher than 10×109/L. There are many causes of elevated cytosines, mainly in the following two categories: 1. Physiological leukocytosis: a physiological reaction that can lead to neutrophilia after strenuous exercise or labor, during pregnancy and childbirth, or under severe cold or heat. In addition, the lymphocytes in the body during infancy will also be higher than normal.
2, pathological leukocytosis: leukocytes is the general term for neutrophils, eosinophils, basophils, lymphocytes and other types of cells. Acute infections caused by various germs such as pneumonia and appendicitis, serious tissue injuries such as major surgery and myocardial infarction can cause increased neutrophils, as well as leukemia and malignant tumors can lead to an increase in abnormal leukocytes. Various viral infectious diseases such as chickenpox, hepatitis, and certain infectious diseases can cause an increase in lymphocytes in the acute phase and an increase in monocytes in the recovery phase. In addition, certain allergic diseases such as bronchial asthma, urticaria and parasitic infectious diseases are causes of elevated eosinophils.
It can be seen that there are various causes of elevated leukocytes, and it cannot be assumed that high leukocyte count is leukemia. When laboratory tests indicate that the leukocyte count is persistently higher than normal, systematic and formal examination and laboratory tests should be completed to clarify the cause and then accurate treatment.
