Differential Diagnosis of Microcytic Hypochromic AnemiaDecreased Body Iron Stores
Normal or Increased Body Iron Stores
- Anemia of chronic disease.
- Defective absorption, transport, or use of iron.
- Iron-refractory, iron deficiency anemia after parenteral iron.
- Atransferrinemia.
- Aceruloplasminemia.
- Divalent metal transporter 1 (DMT1 or SLC11A2) deficiency.
- Ferroportin-associated hemochromatosis with impaired iron export (type 4A).
- Heme oxygenase 1 deficiency.
- Disorders of globin synthesis.
Decreased Body Iron Stores
- Thalassemia.
- Other microcytic hemoglobinopathies.
- Disorders of heme synthesis.
- Sideroblastic anemias.
