Leukocytes is a general term for a group of cells in the blood, including neutrophils, eosinophils, basophils, lymphocytes, etc. The normal range of peripheral blood leukocyte count in adults is (4-10) × 109/L. When the leukocyte count is consistently higher than 10 × 109/L it is considered higher than normal and is called leukocytosis.
The total leukocyte count does not always rise because of disease, but mainly in the following two situations: 1. Physiological leukocytosis: a physiological reaction that can lead to neutrophilia after strenuous exercise or labor, during pregnancy and childbirth, or in severe cold or heat. In addition, the lymphocytes in the body during infancy will also be higher than normal.
2, pathological leukocytosis: acute infections caused by various germs such as pneumonia, appendicitis, serious tissue damage such as major surgery, myocardial infarction, as well as leukemia, malignant tumors and other causes can lead to neutrophilia. Various viral infectious diseases such as chickenpox, hepatitis and recovery from certain infectious diseases can lead to an increase in the number of lymphocytes in patients. In addition, certain allergic diseases such as bronchial asthma, urticaria and parasitic infectious diseases are etiologies that lead to elevated eosinophils.
When the white blood cell count is consistently higher than normal, the patient’s medical history and relevant examinations and tests should be taken into account to make a clear diagnosis and provide timely and accurate treatment.
