Live Program: Wednesday, March 7, 2018 - On-Demand Available
Master Program Number: 18EL-320 (see program format numbers below under Registration)
Educational Track: Technical/Clinical
Topic: Transfusion Medicine
Intended Audience: Hospital Blood Banks, Immunohematology Reference Labs (IRL’s), Laboratory Staff, Managers/Supervisors, Medical Directors, Physicians, Resident/Fellow, Students (MD, MT, SBB), Technologists, Transfusion Safety Officer
Teaching Level: Intermediate, Intermediate to Advanced
Director/Moderator: Isabella Martin, MD, Director of Clinical Microbiology, Dartmouth-Hitchcock Medical Center, Lebanon, NH
Speaker: Amy Malmberg, MLS(ASCP)cm, Supervisor, Immunohematology Reference Lab, Blood Center of the Pacific, San Francisco, CA
After participating in this educational activity, participants should be able to:
- Define and classify low-prevalence and high- prevalence antigens. Discuss their inheritance related to ethnicity.
- Discuss the blood group systems/collections/series associated with commonly encountered antibodies to high and low-incidence antigens and their clinical significance.
- Review the null phenotypes from each blood group system/collection/series that can guide in the identification of an unknown antibody.
- Highlight strategies, explain special testing techniques, and offer tips for approaching identification and resolution of antibodies in these categories.
- Provide transfusion recommendations in the management of patients with antibodies to high or low-prevalence antigens.
This program will explore common situations in immunohematology that can complicate routine antibody screens: the detection and resolution of antibodies to high and low frequency antigens as well as HTLA-like (high titer, low avidity) antibodies. The clinical significance of these types of antibodies, as well as testing strategies used for identification and resolution for each of these will be discussed.
