Design and feasibility of a flexible computerized system for the clinical laboratory, based on the IEEE 488...

Our target is to build a flexible computerized system based on an informational study of the clinical laboratory, which would leave the laboratory staff free to use equipment or modules from different manufacturers interchangeably. This applies to hardware and software. To fulfil this objective, it is necessary that automatic analyzers, microcomputers and minicomputers, have built-in standardized hardware and software interfaces. Technical specifications of the IEEE 488 standardized interface, recommended by the authors, are presented here; this interface is already widely used in instrument interfacing with low-cost microcomputers are minicomputers but has not yet been used for clinical laboratory automatic analyzers. A design for a flexible laboratory based on this interface is presented, with a discussion of the feasibility of such a project.
