Abstract

We report a case of BX in a 27-year-old woman admitted for Cessarian section after diagnosis of placenta previa. An ABO discrepancy was observed, such as, group O in cell typing but group B in serum typing. The patient's red cells were agglutinated by anti-H and show the mixed field agglutination by anti-A,B. The results of adsorption and elution test, saliva test and B transferase test show the presence of B antigen, absence of B substance in saliva and no activity of B-transferase. All of these findings were compatible with BX.
