A long-term low white blood cell count increases the risk of infections and may be caused by a number of different diseases and conditions. High white blood cell count (leukocytosis) means having too many leukocytes circulating in the blood, usually from having an infection.

More serious conditions that may cause high white blood cell counts include blood disorders, including: Leukemia. Lymphoma. Bone marrow disorders such as polycythemia vera or myelofibrosis.

Even worse, it can impair the bone marrow's ability to make red and white blood cells, causing severe anemia and dangerously low numbers of white blood cells. When the number of white blood cells is reduced, your body may have difficulty fighting infections.
