Abstract: 【Objective】 To carry out serological and molecular biological identification of B (A) subtype, and discuss the rational blood transfusion strategy. 【Methods】 Serological and direct sequencing methods were used to detect serotype and genotype of 7 cases of B (A) subtype, and cross matching was performed by saline medium and anti human globulin card to analyze the red blood cells(RBCs) transfusion strategy. 【Results】 The serology results of blood type of 7 samples were similar, with B(A)04/O01 in 3 cases, B(A)04/O02 in 2 cases and B(A)02/O01 in 2 cases. 7 cases of B (A) subtypes were matched with randomly selected blood donors of type O and B on the major side. 【Conclusion】 B(A) subtypes should be identified by genotyping techniques. Washed RBCs of type B and O can be used for B(A) blood type transfusion.
