This course provides an in-depth exploration of blood banking and transfusion medicine, focusing on the principles and practices critical to the collection, testing, processing, storage, and distribution of blood and blood components. Students will study blood group systems, compatibility testing, donor selection, and transfusion reactions, as well as safety guidelines and quality assurance processes. The course also examines advances in transfusion therapy, immunohematology, and the management of transfusion-transmitted diseases, preparing students to apply this dynamic field's concepts in clinical laboratory settings.
