[ABO crossmatching - the bedside test - with a new system].

A new system is described to control the ABO-identity immediately prior to bloodtransfusion (Bedside-test). The system allows the ABO-identity to be checked safely, quickly, and simply. The antiserum, in a liquid and ready-to-use form, is enclosed in four sealed compartments. The compartments are covered with a transparent plastic film. Approximately one drop of blood from the patient and the transfusion sample respectively is injected through the film. The result is available within 10 sec.
