Description

a decrease in the number of neutrophils (white blood cells that respond quickly to infection) in the blood. If a person has less than 1,500 cells/mm3 neutrophils, he or she is considered to be neutropenic and at risk for infection. With fewer than 500 cells/mm3 the risk of infection is very high and gets higher the longer the neutropenia lasts. See also white blood cells.
