Beta-thalassemia minor?,”Thalassemia minor is often confused with iron deficiency anemia. Beta-thalassemia trait has microcytosis out of proportion to the degree of anemia, hemoglobin >10 g/dL
and a disproportionately high RBC count. Iron deficiency usually has a low RBC count and rarely becomes microcytic until hemoglobin is <10 g/dL. Iron supplements offer no benefit for thalassemia minor as patients are usually not iron deficient. Treatment is reassurance with no specific therapy required."
