Agranulocytosis is a condition that occurs when the bone marrow does not produce enough granulocytes or neutrophils (a type of white blood cell) resulting to an extremely low number of granulocytes in the blood. Agranulocytosis is a severe form of neutropenia with absolute neutrophil count (ANC) of less than 100 cells/microliter.
