Neutropenia is an abnormally low concentration of neutrophils in the blood. Neutrophils make up the majority of circulating white blood cells and serve as the primary defense against infections by destroying bacteria, bacterial fragments, and immunoglobulin-bound viruses in the blood. People with neutropenia are more susceptible to bacterial infections, and without prompt medical attention, the condition may become life-threatening.
