Consideration about the usefulness of irregular antibody information acquired from other facilities before transfusion

Abstract

We reviewed irregular antibody information acquired from other facilities before transfusion and investigated whether the information will be useful for blood supply. Of seven patients, six visited our hospital carrying the antibody information, and the remaining patient presented a card indicating that the patient had an irregular antibody. The advantages of acquiring information from other facilities are as follows: shortening of the time to identify irregular antibodies and to decide the blood type to be selected or to judge whether it can be handled in their own facility, and also the prevention of the delayed hemolytic transfusion reaction caused by the absence of certain antibodies. On the other hand, problems such as the method of communicating information and the method of utilizing the information after receiving it were not defined, so it is difficult to judge the situation when the information acquired from other facilities is not consistent with the result from their own laboratory. Moreover, in this study, we found that there are few patients carrying the card with irregular antibody information, as suggested by the Ministry of Health, Labor and Welfare. In the near future, it is hoped that the use of this card will be more widespread.
