Scientific session: What pre-clinical studies teach us about preventing hemolytic disease of the fetus and newborn?

Presented by

Dr. Yoelys Cruz-Leal
Postdoctoral Fellow
Canadian Blood Services, Toronto

Learning objectives

1. Describe the cause of hemolytic disease of the fetus and newborn (HDFN) and evaluate the effectiveness of current prophylaxis.
2. Analyze the proposed mechanisms of action of Rh immune globulin (RhIg) in preventing HDFN.
3. Evaluate the findings of preclinical studies on preventing HDFN, and synthesize the available evidence to develop a comprehensive understanding of the current state of research in this area.
