In sideroblastic anemia due to lead poisoning, which iron studies pattern is typical?

Lead blocks enzymes in heme synthesis, so iron cannot be properly incorporated into heme and instead accumulates in tissues and storage pools. This creates iron overload with elevated ferritin as iron is stored, and more circulating iron raises transferrin saturation. So the typical iron studies pattern is high ferritin paired with high transferrin saturation.
