HbA2 determination is the most decisive test for β-carrier detection although it can be disturbed by the presence of δ-thalassemia defects. In α-thalassemia, HbA2 can be lower than normal and it assumes significant value when iron deficiency is excluded. In addition to complete blood count (CBC), hemoglobin electrophoresis is the first diagnostic test. Fractions of hemoglobin A, A2, F, H, E, and other variants are measured.
