An 18-year-old man is recently diagnosed with beta-thalassemia minor. His hemoglobin is 10.5 g/dL, and he feels well. Which of the following findings is characteristic of this condition?
An increased amount of HbF or HbA2 would be expected. As beta-chains are decreased in beta-thalassemia, the excess alpha-chains combine with gamma- and delta-chains to make HbF and HbA2, respectively.
an increased amount of fetal hemoglobin (HbF) or hemoglobin A2 (HbA2)
increased osmotic fragility of the red cells
absent bone marrow iron
increased macroglobulins in the serum
