WebExcess α globin chains are unable to form tetramers leading to their precipitation and accumulation in the red blood cell. This damages the cell and results in a chronic and severe hemolytic anemia. Patients require regular transfusions. Table 2. Laboratory Findings of β-Thalassemias2. β-Thalassemia State. WebA high mean corpuscular volume (MCV) may occur due to extreme reticulocytosis. Hemolytic anemia in the setting of a low reticulocyte count is rare but can occur and is suggestive of severe disease. Autoimmune hemolytic anemia is diagnosed by detection of autoantibodies with the direct antiglobulin (direct Coombs) test (see figure ).
