29- An adult patient suspected of having thalassemia presents with the following hemoglobin electrophoresis pattern: HbA=0.0%, HbF=92%, HbA2=8%. This pattern best fits a diagnosis of:

C- α -thalassemia trait
D- ß-thalassemia minor
E- α -thalassemia major
30- Select the laboratory test result that is consistent with a diagnosis of α-thalassemia minor:
