Flow Cytometry as a Diagnostic Aide to Hematology Analyzers: A Practical Approach to the Evaluation of Abnormal WBC Differentials

12:00 PM to 1:00PM (Americas) Central Time (US & Canada)

Dr. Olga Pozdnyakova, MD, PhD, Associate Pathologist, Hematopathology Division, Associate Medical Director, Hematology Laboratory, Brigham & Women's Hospital, Boston, MA

Multiparameter flow cytometry has become an integral tool in the work-up of abnormal WBC findings, allowing for rapid and accurate identification of abnormal cell populations, cell lineage assignment and assessment of clonality. This presentation will discuss a series of cases that demonstrate the utility of flow cytometry in the diagnostic workup of hematologic disorders presenting with abnormal WBC differential and incorporation of relevant criteria from the revised WHO Classification of Tumors of Hematopoietic and Lymphoid Tissues.


  • Recognize common abnormal WBC morphology findings on peripheral blood smears
  • Interpret flow cytometry reporting in the context of abnormal WBC differentials
  • Review appropriate reflex testing based on flow cytometry results
