ANC   

  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 ANC may be used to check for infection, inflammation, leukemia, and other conditions. The lower a person's ANC is, the higher the risk is of getting an infection. Having an ANC of less than 500 means there is a high risk of getting an infection. Cancer treatment, such as chemotherapy, may reduce the ANC. Also called absolute neutrophil count.
