absolute neutrophil count  listen  (AB-soh-loot NOO-troh-fil kownt)

  A measure of the number of neutrophils in the blood. Neutrophils are a type of white blood cell. They help the body fight infection. An absolute neutrophil count may be used to check for infection, inflammation, leukemia, and other conditions. The lower a person's absolute neutrophil count is, the higher the risk is of getting an infection. Having an absolute neutrophil count of less than 500 means there is a high risk of getting an infection. Cancer treatment, such as chemotherapy, may reduce the absolute neutrophil count. Also called ANC.
