Abstract
For the blood transfusion, the precise blood grouping is the most important matter. Nevertheless, even now, cases of unfortunate outcome due to blood transfusion with incompatible blood thereby caused severe side reactions are being noted not infrequently. The authors also encountered one of such cases. Therefore, the cases are reported and precautions to be taken in the examination procedure are stated in the present paper.
In the present case, due to inadequate examination procedures, blood containing B-Group antigen was given to a recipient possessing A-Group (AIM) blood, thus severe side reactions were caused. In view of the following results of the serologic examinations, the authors pointed out that the blood transfusion was made with blood of incompatible ABO blood grouping with the recipient's group. The authors made clear by reexamination of the donor's blood group that the results of the blood grouping was wrong.
1. The normal β-agglutinin titre of the recipient was unusually as high as 2560.
2. By means of over layer method, we found groupspecific anti-B precipitin in the recipient's blood serum. The precipitin titre was found to be 32, and the amount of precipitin was 1.
3, Neither univalent nor bivalent irregular agglutinin was recognized in the recipient's blood serum.
