The general clinical pathology orientation month is the first rotation scheduled for all incoming first year residents. The purpose is to provide an introduction to certain areas of clinical pathology such as transfusion medicine and hematopathology. The rotation consists of two weeks of intense didactic sessions covering the basic fundamentals in transfusion medicine such as ABO/Rh, antibody screening, transfusion reactions, and apheresis. The following two weeks focus on the introduction to peripheral blood smears, and bone marrow biopsies. Morphology and immunohistochemistry are thoroughly discussed and flow cytometry, immunology, hematology and coagulation are also covered. In addition, the resident will become familiarized with the different areas of the clinical laboratory, learn about the various analyzers and laboratory tests, and meet the clinical laboratory team.
