Panel D shows the results of the nitroblue tetrazolium test in normal neutrophils: phagocytosis results in dark-blue staining of the cytoplasm. Panel E shows the results of the nitroblue tetrazolium test in neutrophils from a patient with chronic granulomatous disease: there is no phagocytosis and thus no dark-blue cytoplasmic staining.
