Course provided by LabCE.

This course defines and discusses in depth the disorder alpha thalassemia, its genetics, and associated laboratory findings. Clinical manifestations of alpha thalassemia major, intermedia, and minor are defined and differentiated. Laboratory findings associated with all three manifestations are covered in detail. The course addresses special procedures, including hemoglobin electrophoresis and brilliant cresyl blue stain, and concludes with an in-depth case study.

Objectives

  • 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.
