Routine And "Not-So-Routine" Methods In Transfusion Science
Routine and "Not-So-Routine" Methods in Transfusion Science (9834-10)
Review basic principles in compatibility testing and explore the advantages as well as the pitfalls of both routine and special methods. Study all the crucial steps in pretransfusion compatibility testing from identification of patient and sample to the actual crossmatch and preparation of blood units to leave the laboratory. Identify unexpected red cell alloantibodies by recognizing reaction patterns, excluding antibodies with panel cells and phenotyping red cells. Relate theory, clinical observations, and practical approaches to the investigation of a positive direct antiglobulin test.
