ABO and RhD Blood Grouping and Typing

ABO and RhD blood grouping and typing are fundamental serological techniques in transfusion science, essential for ensuring compatible blood transfusions. This topic is designed for tertiary students in Zambia enrolled in Biomedical Sciences, Hematology, or Medical Laboratory programs. It covers the principles of forward and reverse grouping, the use of monoclonal antisera, interpretation of agglutination reactions, and the identification of RhD status. Students will learn to resolve common discrepancies, such as mixed-field agglutination or weak D phenotypes, and apply Landsteiner's rules to verify results. Proficiency in ABO/RhD typing is crucial for pre-transfusion testing, hemolytic disease of the newborn prevention, and forensic applications. Mastery prepares learners for university examinations and professional practice in hospital laboratories and blood transfusion services throughout Zambia, contributing to reduced transfusion reactions and improved patient outcomes.
