[Groupamatic in the general organization of collecting and utilization of blood at C.N.T.S].

The automatization of immunohematological tests on Groupamatic equipments and its integration in a data management system of blood units and donor files has been brought about progressively, takinginto account the initiator status of the C.N.T.S. and its priviliged relationship with the manufacturer. A set of different problems was thus successively studied, the solutions of which lead to the development of new techniques, concerning the machine itself and its surroundings: --blood collection: -taking of blood sample on vacutainers containing anti-coagulant, without dilution, at a constant level and clot free; --identification: -connection between blood sample and blood unit by the creation of an identification number on twin labels (2 part card); -donor blood donation connection; --utilization of Groupamatic results: -edition of result listings; -study and use of an automated labelling of blood units; --setting up and daily updating of donor files: -blood collection data management; -creation of a badge--link between blood donation, files and donors. These constant improvements of both system and techniques have helped to put us within reach of the goal set as early as 1963 with Dr. C. Matte, that is to say the establishment of a fully automated system avoiding any intervention other than blood collection. Thus, due to the suppression of retranscription, this system increases the safety and enables the use of previously known donor characteristics.
