The WBC count is often increased as a reaction of the bone marrow to infection or inflammation. Certain bacterial and viral infection can trigger leukocytosis. Leukocytosis is also related to strong immune reactions like asthma and other allergy attacks. Some of the most serious and life-threatening cases of leukocytosis are associated with the diseases of the bone marrow. An elevated WBC count of greater than 30,000 per cubic mm of the adult human blood could indicate an underlying bone marrow disorder including leukemia or blood cancer. Other causes of leukocytosis include stress, intake of certain medications like lithium and beta agonists, surgical removal of the spleen, hemolytic anemia and cancer. Both physical and emotional stress results in an elevation of the WBC count. Physical stress can be due to excessive exercising, anesthesia, seizures and other illness. ( 2)
Depending on the type of individual cell increased, leukocytosis can be subclassified as below: Name of the cell
The condition caused by the abnormal increase
Neutrophils
Neutrophilia
Lymphocytes
Lymphocytosis
Monocytes
Monocytosis
Eosinophils
Eosinophilia
Basophils
Basophilia
Laboratory findings suggest that increase in neutrophils makes a significant contribution to leukocytosis, although other component cells of WBC may also increase the WBC count.
