Laboratory information system test environment: validate upgrades, prevent disasters, and assist training.

A laboratory information system (LIS) test environment allows the laboratory to run and test programs without affecting the current production environment. This is essential for successfully introducing system enhancements and upgrades because it allows the LIS manager to uncover software errors before introducing them into the actual LIS system. A test environment is also a useful tool for training employees. In addition, a test environment enables laboratories to validate software before use in the live environment, which will probably be required by the Food and Drug Administration and the Health Care Financing Administration inspectors now that LISs are considered medical devices. This article examines the benefits, uses, and limitations of an LIS test environment; discusses the computer resources required; and explores the process of installing and validating a software release.
