In this session, members of the College of American Pathologists (CAP) Transfusion Medicine, Apheresis, and Cellular Therapy Committee will review the current state of proficiency testing (PT) regulations and objectives. Issues with specific PT surveys will be discussed, including transfusion-related cell counts and antibody titers.
Define the regulations that require proficiency testing (PT), examples of tests that are graded versus ungraded, and the implications of regulations.
Appreciate common errors seen in PT, using Transfusion-Related Cell Counting as an example.
Identify difficulties in comparing antibody titer results between laboratories as highlighted by PT.
