Studies of the Subgroups of Blood Groups A and AB

[摘要] 1. 1. The serological examinations of the blood of an individual belonging to subgroup A3B are described.2. 2. Of all red cells available, A3B cells give the weakest reactions with B serum and therefore provide the most sensitive testing media for this serum.3. 3. Serum from group B donors vaccinated intravenously with a solution of A and B factors may produce strong agglutination of A3B cells. Titrations of such a serum are presented in detail and serve to emphasize the great advantage of using “immunized” persons as donors of blood grouping serum.4. 4. The case described constitutes an exception to the currently accepted theory of the inheritance of the agglutinogen A3 for which there is no ready explanation.
