Neutrophils are white blood cells that are important for
protection against infections. These frontline fighters against
infection release chemicals such as hydrogen peroxide to kill
germs or clean up wounds.   Increased risk of infection can
happen when the body does not have enough neutrophils in the
blood stream; when neutrophils cannot travel through the
bloodstream to sites of infection efficiently; or when the
neutrophils are unable to make oxidants such as hydrogen
peroxide to kill infecting microbes.   Learn more about the role
of neutrophils in primary immunodeficiency diseases (PIDD).
