Transfusion Medicine is a specialized field of clinical pathology that focuses on the collection, testing, processing, storage, and clinical administration of blood and blood components. This course covers the principles and practices of blood transfusion, including donor selection, blood banking procedures, compatibility testing, and management of transfusion reactions. It also explores the immunological aspects of transfusion, infectious disease screening, component therapy, and the application of transfusion practices in various clinical settings. Emphasis is placed on patient safety, regulatory requirements, and advancements in transfusion therapies, preparing students to understand and navigate the complexities of modern transfusion medicine.
