Sideroblastic Anemias (SA)

Sideroblastic anemias (SA) are described as a heterogeneous group of anemias. There are three general types of SA, acquired, idiopathic, and hereditary. Regardless of the type of pathogenic mechanism, all types of sideroblastic anemias are characterized by:

  • Increases in total body iron
  • The presence of ringed sideroblasts in bone marrow.
  • Presence of microcytic, hypochromic RBC’s.
  • Decreased MCH and MCHC values.
  • Decreased Retic count.
