Peripheral smear results in iron deficiency anemia are as follows:

  • RBCs are microcytic and hypochromic in chronic cases

  • Platelets usually are increased

  • In contrast to thalassemia, target cells are usually not present, and anisocytosis and poikilocytosis are not marked

  • In contrast to hemoglobin C disorders, intraerythrocytic crystals are not seen
