Analytical methods and quality assurance

Abstract

A laboratory information management system (LIMS) written in Visual Basic using Microsoft Access 95 database and operating in the Windows 95 environment has been developed. The system provides easy entry of all test parameters including sample set identification, sample type, date samples taken and received, sample disposal procedures, identification of technicians responsible and individual sample identification. The system allows input of ASCII files from intelligent laboratory instruments. Data, including reports, can be easily imported or exported in text or ASCII format. Printable customized laboratory work sheets and final reports are designed using parameters stored in a separate protected but editable database. Minimal operator input is required for the calculation and electronic mailing of results, as well as the storage and archival of all data. Report files can be delivered rapidly using email. An up‐to‐date list of analyses pending is available to the laboratory manager providing information required to plan laboratory activities such as staffing and consumables purchasing. The system provides easy sample tracking.
