RESUMO
The clinical laboratory's use of computers has evolved beyond the single minicomputer stand-alone system. Our laboratory information system is now part of an institutional network. The laboratory also uses smaller systems and workstations for a wide variety of functions, often with much data duplication among systems. We have been developing a network-based virtual database for laboratory test information. This system uses World Wide Web standards for hypertext and multimedia displays, which allows for the display of information retrieved from various department computer sources without the necessity of data duplication, modification of existing systems, or centralization of data. The medical technologists can continue to write testing procedures on their word processors. Maintenance of reference values, specimen requirements, etc., can continue as a laboratory information system function. Yet information from all of these disparate sources can be viewed in a consolidated format that has platform independence.
