Detection of Unexpected RBC Antibodies

This topic provides an in-depth exploration of the laboratory techniques used to detect unexpected (irregular) red blood cell antibodies, a critical step in pre-transfusion testing. Students at Zambian universities and colleges will learn the principles and procedures of key methods, including the Bovine Serum Albumin (BSA) Indirect Antiglobulin Test (IAT), saline IAT, and the Direct Antiglobulin Test (DAT). The module covers the use of reagent red cells, the importance of homozygous cells for detecting dosage effects, and the interpretation of agglutination grading. Procedures for antibody screening and identification are detailed, along with quality control measures like Coombs Control Cells. This practical knowledge is fundamental for learners in medical laboratory science programs, as it ensures they can competently perform antibody investigations to prevent acute and delayed hemolytic transfusion reactions. Proficiency in these techniques is assessed in practical examinations and is a core requirement for employment in hospital blood banks and the Zambia National Blood Transfusion Service.
