Neutrophil blood test

Neutrophils help your immune system fight infections and heal injuries. They are the most common type of white blood cell in your body. A neutrophil blood test, or absolute neutrophil count, can identify whether your body has enough neutrophils or if your count is above or below average. Common causes for high neutrophil levels include infections, inflammation, injury, certain types of leukemia, and reactions to certain drugs. Low levels of neutrophils can be caused by infection, chemotherapy, bone marrow disorder, vitamin deficiency, or autoimmune disease. Common tests to check neutrophil levels include complete blood count (CBC) tests, absolute neutrophil count (ANC) and bone marrow biopsy.
