Leukocyte 5.8 is within the normal range. The total number of leukocytes in human blood is relatively stable, and the main role of leukocytes is immunization and removal of pathogens. The normal range of leukocyte count is (4 to 10) x 10^9/L, so a leukocyte count of 5.8 x 10^9/L falls within the normal range. Usually, the white blood cell count may be elevated during premenstrual period, pregnancy, childbirth and breastfeeding, which is generally a normal physiological phenomenon. The white blood cell count is elevated with acute inflammation, trauma, hemorrhage, massive burns, acute myocardial infarction, and leukemia when there is an acute inflammation in the body. In some viral infections, such as influenza, viral hepatitis, cytomegalovirus infection, typhoid fever, paratyphoid fever, leukopenia, autoimmune diseases and other diseases and physical and chemical injuries will cause a decrease in white blood cell count. Prompt hospitalization is required.
