Pancytopenia is characterized by decreased numbers in which blood components?

• A. Decreased numbers in all blood cells
• B. Decreased numbers of white blood cells
• C. Decreased numbers of red blood cells
• D. Decreased numbers of granulocytes and monocytes

Answer: (A)

Pancytopenia means a broad suppression of blood cell production, so all major blood cell lineages are reduced. That includes red blood cells (causing anemia), white blood cells (increasing infection risk), and platelets (leading to bleeding or bruising). So the description of decreased numbers in all blood cells best fits this condition. If only white cells were low, it would be leukopenia; if only red cells were low, that would be anemia; and a drop in granulocytes and monocytes refers to a subset of white cells, not the entire spectrum.
