Requests for retrieval of laboratory results from archive.

The design of laboratory archives depends to a large extent on frequency and type of access required. This article reports a study in which all requests for laboratory archival data were tabulated carefully. Such requests are infrequent and usually involve specific test results. An inexpensive, efficient, and convenient method of storing such data is described, employing a laboratory computer and magnetic tape-to-microfiche software. The efficiency of this system permits indefinite storage which may be desirable in view of the medico-legal climate.
