This is because laboratories set their own reference ranges based on the populations they serve. In general, for adults a count of more than 11,000 white blood cells in a microliter of blood is considered high.<\/p>\n<p>A high white blood cell count usually means one of the following has increased the making of white blood cells:<\/p>\n<ul>\n<li>An infection.<\/li>\n<li>Reaction to a medicine.<\/li>\n<li>A bone marrow disease<\/li>\n<li>An immune system issue.<\/li>\n<li>Sudden stress such as hard exercise.<\/li>\n<li>Rauchen.<\/li>\n<\/ul>\n<p>Specific causes of a high white blood cell count include:<\/p>\n<ul>\n<li>Allergy, especially severe allergic reactions<\/li>\n<li>Asthma <\/li>\n<li>Bacterial, viral, fungal or parasitic infections<\/li>\n<li>Verbrennungen <\/li>\n<li>Churg-Strauss syndrome <\/li>\n<li>Medicines, such as corticosteroids and epinephrine<\/li>\n<li>Hay fever <\/li>\n<li>Leukemia <\/li>\n<li>Lymphoma <\/li>\n<li>Myelofibrosis (a bone marrow disorder)<\/li>\n<li>Polycythemia vera &mdash; a type of blood cancer.<\/li>\n<li>Pregnancy<\/li>\n<li>Rheumatoid arthritis <\/li>\n<li>Sarcoidosis <\/li>\n<li>Rauchen.<\/li>\n<li>Tuberculosis <\/li>\n<li>Vasculitis <\/li>\n<li>Whooping cough <\/li>\n<\/ul>\n<p>A test a health care provider orders to diagnose a condition can reveal a high white blood cell count. A high white blood cell count is rarely found by chance.<\/p>\n<p>Talk to your care provider about what your results mean. A high white blood cell count plus results from other tests might show the cause of your illness.
