Educational Track: Technical/Clinical
Topic: Transfusion Medicine
Intended Audience: Facilities that perform molecular testing, Hospitals, Hospital Blood Banks, Immunohematology Reference Labs (IRL’s), Laboratory Staff, Medical Directors, Physicians, Resident/Fellow, Students (MD, MT, SBB), Technologists
Teaching Level: Intermediate

Director/Moderator: Nancy M. Dunbar, MD, Medical Director, Blood Bank, Department of Pathology and Laboratory Medicine, Dartmouth-Hitchcock Medical Center, Lebanon, NH
Speaker: Meghan Delaney, DO, MPH, Chief of Pathology & Laboratory Medicine, Director of Transfusion Medicine, Children’s National Health System, Washington, DC

Learning Objectives

After participating in this educational activity, participants should be able to:

  • Explain current testing recommendations for management of pregnant women who have serological weak D.
  • Discover how molecular testing can clarify serologic weak D testing results.
  • Examine patient cases where molecular RhD testing guided pregnancy management.

Program Description

Clarification of the underlying genotype of pregnant patients that have weak D phenotypes is important for pregnancy management including need for Rh Immune Globulin prophylaxis and red cell selection, if transfusion is indicated. Current guidelines describe recommendations for the application of molecular RhD testing in this setting. This one-hour case based program will review current recommendations for molecular RhD testing and illustrate how this testing guides the management of pregnant patients with serological weak D.
