ABO Blood Group System

Understanding the ABO blood group system is fundamental to safe and effective transfusion practices. This activity offers a comprehensive review of the ABO system, including the structure and function of ABO antigens and antibodies, and the genetic and biochemical basis of blood type determination. The activity explores methods used in blood typing, common causes of typing discrepancies, and the clinical significance of these variations. Special attention is given to the risks of ABO incompatibility, including hemolytic transfusion reactions and hemolytic disease of the newborn, and strategies for selecting appropriate blood products to minimize these risks. Designed for interprofessional healthcare teams, this activity reinforces the importance of accurate blood typing and compatibility assessment in both routine and emergency transfusion settings. By enhancing knowledge and promoting collaboration among clinicians, laboratory personnel, and other healthcare providers, the activity promotes safer transfusion practices and improved patient outcomes. Participants gain the critical knowledge needed to prevent adverse events related to ABO incompatibility and ensure the appropriate administration of blood products based on patient-specific factors.
