This article discusses the importance of accurately identifying rare blood types in clinical laboratories to prevent life-threatening transfusion reactions. The B3 phenotype, which is characterized by weak expression of B antigens, is particularly challenging to identify and is often misdiagnosed. The article presents a case study where a B3 phenotype was initially misidentified as para-Bombay due to a lack of laboratory practices and experience. The authors emphasize the need for rigorous training and adherence to standard operating procedures to improve the accuracy of blood type determinations and enhance patient safety.
