This course covers all aspects of white blood cell morphology, including identifying changes in morphology in granulocytes. Addresses Barr bodies, Dohle bodies, Auer rods, vacuoles, hypersegmented granulocytes, and hyposegmented granulocytes. Excellent as a refresher or for clinical laboratory science students.

Objectives

  • Explain the importance of identifying changes in granulocyte morphology.
  • Define, describe, and explain the relationship of Barr bodies to abnormal morphology.
  • Discuss nuclear hypersegmentation and hyposegmentation, with respect to: definition, appearance, composition, and significance.
  • Discuss nuclear hypersegmentation and hyposegmentation, with respect to: hypersegmented granulocytes and hyposegmented granulocytes.
  • Identify each of the following cytoplasmic variations: Dohle bodies, Auer rods, vacuoles, and abnormal granulation.
  • Identify and describe the morphological changes associated with Pelger-Huet anomaly, Chediak-Higashi anomaly, Alder-Reilly anomaly, and May-Hegglin anomaly.
