What are the risks associated with blood transfusion? As a laboratory professional involved in blood preparation for transfusion, do you know what steps you can take to minimize those risks? If a patient starts to exhibit various symptoms during or after a transfusion, would you know how to interpret those symptoms and what actions to take to prevent harm to the patient? These are all important questions that are asked and answered by our new course, Transfusion Reactions. This course covers important types of transfusion reactions, including acute hemolytic transfusion reactions, transfusion-related acute lung injury, and transfusion-associated graft versus host disease. If you are a part of the health care team that is involved in the processing and administration of blood products, this course will reinforce those policies and procedures that you may already know, but are important to review. This course will update your knowledge about the various types of reactions that occur and their associated symptoms. Even though you may not be involved in the clinical part of the transfusion process, it is important to understand the big picture to recognize how important your job is to ensure patient transfusion safety.
