After participating in this educational activity, participants should be able to:
- Describe how molecular testing is used to determine blood group antigen phenotypes.
- Describe how stem cell transplant or chimerism can complicate red cell phenotyping.
- Describe how red cell alloimmunization can impact decision making and planning around hematopoietic stem cell transplant.
- Use case studies to illustrate the challenges of phenotyping in these scenarios.
Molecular testing for blood group antigen phenotypes is becoming a commonly used in the toolbox of transfusion medicine, especially in patient populations with high alloimmunization rates, including those with hemoglobinopathies. The ability to phenotype using serology or molecular methods can be hampered by chimerism whether natural or due to incomplete engraftment. In addition, availability of blood products for the pre-transplant period and the time immediately following the transplant for patients who are highly alloimmunized can add another barrier to life-saving treatment. Cases will be used to illustrate these points.
