A high white blood cell count is a sign of an unstable environment in the body. The normal range of peripheral blood leukocyte count is (3.5-9.5) × 109/L. When the leukocyte count is consistently higher than 9.5 × 109/L it is considered higher than normal and is called leukocytosis.
Leukocytes are the general term for neutrophils, eosinophils, basophils, lymphocytes, and other types of cells in the blood, and there are two main types of causes of elevated leukocytes: physiological and pathological increases.
1, physiological leukocyte increase: after strenuous exercise or labor, pregnancy and childbirth, or under severe cold or heat, some people can appear neutrophil increase physiological response. In addition, infants and young children, due to the development of the immune system, may appear in the body lymphocytes than the normal high phenomenon.
2, pathological leukocytosis: acute infections caused by various germs, serious tissue damage, as well as leukemia, malignant tumors and many other causes can lead to neutrophilia. Certain allergic diseases, such as bronchial asthma, urticaria and parasitic infectious diseases are the causes of eosinophilia. Various viral infectious diseases such as chickenpox and hepatitis and recovery from certain infectious diseases can lead to an increase in the number of lymphocytes in patients. If a large number of abnormal forms of leukocytes are present, diseases such as malignant tumors of the hematopoietic system, such as leukemia and myeloproliferative neoplasms, need to be considered.
As a result, there are various reasons for the increase in white blood cells, and when laboratory tests indicate that the number of white blood cells is consistently higher than normal, prompt consultation should be made to improve the systematic and formal examination and laboratory tests to make a clear diagnosis and then provide timely and accurate treatment.
