Cytopenia

Cytopenia is a reduction in the number of mature blood cells.^[1] It takes a number of forms:

• Low red blood cell count: resulting in anemia.
• Low white blood cell count: leukopenia or neutropenia. Because neutrophils make up at least half of all white cells, they are almost always low in leukopenia .
• Low platelet count: thrombocytopenia.
• Low granulocyte count: granulocytopenia
• Low red blood cell, white blood cell, and platelet counts: pancytopenia.
