[2025-09-30T17:14:16.899992] [PI reasoning] **Evaluating electrophoresis results**

The question is about what shows electrophoresis results in alpha-thalassemia trait. I know that hemoglobin electrophoresis typically shows normal HbA2 and HbF because the alpha-globin chains are deficient but don’t affect the ratios significantly. So, option B, which states normal HbA and HbF, seems accurate. Option C suggests decreased HbA2 — while minor cases may show slight decreases, it’s usually normal. Standard teaching confirms that for alpha-thalassemia trait, we see microcytic anemia with normal electrophoresis results. I’m planning to find citations to support this.
