Hi
Sideroblastic anemia is primarily a laboratory diagnosis, made on the basis of bone-marrow examination with Prussian blue stain. The history and physical examination can provide certain clues, but they usually do not pin down the exact diagnosis. Workup may include a complete blood count (CBC), peripheral smear, iron studies (eg, ferritin and total iron-binding capacity [TIBC]), bone marrow aspiration and biopsy, and other studies as appropriate.
Hope that helps!
