Leukocytes is a general term for a group of cells in the blood such as neutrophils, eosinophils, basophils, and lymphocytes, of which neutrophils account for up to 50-70% of the total number. In adults, the normal range of peripheral blood leukocyte count is (4-10) × 109/L. When the leukocyte count is consistently higher than 10 × 109/L or neutrophils higher than 7 × 109/L is considered higher than normal, it is called leukocytosis. There are many reasons for elevated leukocytes, mainly the following two categories: 1, physiological leukocytosis: some people after strenuous exercise or labor, pregnancy and childbirth, or cold, hot conditions can lead to a transient increase in neutrophils physiological response.
2, pathological leukocytosis: acute infections caused by various germs such as pneumonia, appendicitis, etc., acute bleeding or hemolysis such as acute hemolytic bleeding, serious tissue damage such as major surgery, myocardial infarction, etc., as well as leukemia, malignant tumors and other causes can lead to neutrophilia.
As a result, there are various causes of neutrophil-based leukocytosis. When the laboratory tests indicate that the number of leukocytes or neutrophils is consistently higher than normal, you should consult a doctor promptly to improve the systematic and formal examination and laboratory tests to make a clear diagnosis and then carry out timely and accurate treatment.
