Aplastic anemia is a condition where
bone marrow does not produce sufficient new
cells to replenish
blood cells. The term 'aplastic' means the marrow suffers from an
aplasia that renders it unable to function properly.
Anemia is the condition of having fewer red blood cells than normal, or fewer than needed to function properly. Typically, anemia refers to low red blood cell counts, but aplastic anemia patients have lower counts of all three blood cell types:
red blood cells,
white blood cells, and
platelets.
