title: [Automation of the immunohematology laboratory].
abstract: Automation finds a particularly justified application in the field of immunohematology in which any human failure can have dramatic consequences for the patients. The purposes of automation, indissociable from computerization, were reminded by the French regulatory: to decrease the risks of human error linked to each step of the tests performed; to guarantee a reliable traceability of all the elements having contributed to the test process; to manage all the alarms of dysfunction of the system. The main devices available today permit automation of a part of the pre-analytical phase and of all the steps of the analytical phase by the realization in routine of ABO-RH1 grouping, phenotyping, of irregular antibody screening and of compatibility testing. They use the reaction of agglutination either in micro-plates or in filtration. One distinguishes two types of materials: full automates managing all the steps from the sample positioning on the carrier down to the final result without any handling of the samples (Autovue, Galileo, ID gel station, Qwalys, Tango, Techno) and the semi-automates, which require intervention of an operator for the phases of centrifugation, stirring and incubation (Mitis 2, Hemos, Rosys, Swing) the reading being automated for all. All include the possibility of a connection to the central data processing system . If some devices allow the choice of reagents, others can only work with the reagents supplied by the manufacturer. In all the cases, optimization of the automated systems implies a specific training of the staff and the strict compliance with the standard operating procedures by each individual.
