A decrease below normal levels in the concentration of neutrophils in the blood, (neutrophil – a type of white cell.)
The principal phagocyte (microbe-eating cell) in the blood; this blood cell is the main cell that combats infections. Often, it is not present in sufficient quantities in patients with acute leukaemia or after chemotherapy. A severe deficiency of neutrophils increases the patient’s susceptibility to infection. A neutrophil may be called a “poly” (polymorphonuclear neutrophil) or “seg” (segmented neutrophil) because its nucleus has several lobes.
