Educational Track: Technical/Clinical
Topic: Transfusion Medicine
Intended Audience: Directors, Hospitals, Hospital Blood Banks, Immunohematology Reference Labs (IRL’s), Laboratory Staff, Managers/Supervisors, Medical Directors, Nurses, Physicians, Research Scientists, Residents/Fellows, Scientists, Students (MD, MT, SBB), Technologists, Transfusion Safety Officers
Teaching Level: Intermediate to Advanced
Director/Moderator: Geoffrey Wool, MD, PhD, Assistant Professor, Transfusion Medicine Service, University of Chicago, Chicago, IL
Speaker: Christopher A. Tormey, MD, Associate Professor of Laboratory Medicine and Lecturer in Molecular Biophysics and Biochemistry, Yale University; Medical Director, Transfusion Medicine Service, Laboratory Medicine, Yale-New Haven Hospital, VA Connecticut Healthcare System; Director, Transfusion Medicine Fellowship, Yale School of Medicine, New Haven, CT
After participating in this educational activity, participants should be able to:
- Describe kinetics of antibody development, including evanescence and anamnestic response.
- Apply principles of immunoglobulin production to policy development for antibody screen expiration.
- Identify situations where the extension of antibody screen expiration date could increase patient risk for hemolytic reaction.
Antibody screens are generally repeated every three days in recently transfused or pregnant patients, given the risk of new antibody formation. In patients without recent transfusion or pregnancy, the interval between antibody screens can be extended and this is typically convenient for pre-operative patients distant from the hospital. However, the optimal time to extend expiration time in select patient populations is not known. This eCast will also discuss the timing of antibody development and evanescence, as they impact compatibility testing.

Dr. Christopher Tormey is pathologist (board certified in Clinical Pathology as well as Blood Banking/Transfusion Medicine) in the Department of Laboratory Medicine at Yale University. Clinically, Chris is the Medical Director of the Transfusion Service at Yale-New Haven Hospital (New Haven, CT), also providing clinical pathology, transfusion, and laboratory hematology services at Yale-New Haven Hospital & the VA Connecticut Healthcare System (West Haven, CT). From the research standpoint, Chris has several investigative interests including: alloimmunization to non-ABO antigens in the setting of transfusion or pregnancy; examining the platelet storage lesion; and optimizing test performance/interpretation in hemostasis assays. In addition, Chris is also the Director of the Transfusion Medicine fellowship at Yale and teaches medical/PA/nursing students, residents, and fellows at the Yale School of Medicine.
