[Quality assurance in preoperative autologous blood collection from the viewpoint of the transfusion medicine physician].

The overall risk of autologous hemotherapy, consisting of the risks due to donation and transfusion, has to be lower than that of homologous hemotherapy. To maintain the advantage of autologous blood, for example preoperative blood deposit, it has to be collected and prepared according to the guidelines on the production of homologous blood, except some obvious deviations concerning donor criteria. In this paper we recommend measures for the quality assurance in autologous predeposits from the point of view of transfusion medicine.
