Not present in sideroblastic anemia is
Ref Harrison 19 th ed pg 628 when the marrow smear is stained for iron, 20-40% of developing erythroblasts--called sideroblasts--will have visible ferritin granules in their cytoplasm. This represents iron in excess of that needed for hemoglobin synthesis. In states in which release of iron from storage sites is blocked, RE iron will be detectable, and there will be few or no sideroblasts.
