The distinguishing finding in beta thalassemia is a hemoglobin electrophoresis with the finding of elevated Hgb A2 and F. Both will be increased in beta thalassemia trait without iron deficiency, and will be normal or decreased in alpha thalassemia and isolated iron deficiency anemia. Carrier screening for hemoglobinopathies is done with a blood test. Since the test results are useful to rule out sickle cell and other blood disorders, it is also called 'Hemoglobin evaluation test' or 'Sickle cell screen'.
