Abstract: Blood group gene polymorphism holds significant importance in the fields of genetic research, clinical blood transfusion, and transplant immunology, as it determines the polymorphism of blood group antigens. In recent years, third-generation sequencing (TGS) technology, also known as single-molecule sequencing, has emerged as a research hotspot in the precision medicine genetic testing industry, opening a new door for the entire field of genetics. Research findings on blood group genes based on TGS technology have been successively published, continuously expanding the application boundaries of this technology in blood group polymorphism analysis. This review summarizes the latest advancements in TGS technology for studying blood group gene polymorphism and its applications in clinical transfusion medicine.
