The selection and artificial preparation of high-titered test serums, the study of the cause and prevention of hemolytic transfusion reactions, the consideration of the role of subgroups and intragroup agglutinins in transfusion accidents, and the adoption of a simple, accurate technic for determination of blood grouping and compatibility have been described. All are parallel actions directed toward a single purpose, the transfusion of blood with the greatest simplicity and the least possible delay in laboratory procedure, with observance of the best known standards of safety.
Another major obstacle to the dispatch of blood transfusion service in large municipal hospitals is the inaccessibility of blood donors. There are delays, inefficiency and tragic results attendant to location of friends and relatives and the laboratory search for compatible and suitable bloods for patients whose bloods are of the rare groups. Occasionally, there is an emergency which does not permit even the time used
