  • Define Alpha Thalassemia.
  • List the clinical manifestations of the various forms of Alpha Thalassemia.
  • Compare and contrast laboratory findings for Alpha Thalassemia.
  • Differentiate among the various forms of Alpha Thalassemia.
  • Identify synonyms for the various forms of Alpha Thalassemia.
  • Correlate each type of Alpha Thalassemia with its genetic nomenclature/designation.
  • Explain the molecular basis for the various forms of Alpha Thalassemia (Chromosome associated with Alpha Thalassemia; and the degree of defect for the various forms of Alpha Thalassemia).
  • Interpret routine laboratory results for the case given and arrive at a differential diagnosis.
  • Interpret special hematology tests (Hemoglobin electrophoresis; Special stains).
  • Suggest laboratory tests to confirm this presumptive diagnosis; and suggest explanations for discrepancies among laboratory tests.
