LabScanner is a simple data mining application that is designed for use by pathologists and clinical laboratory personnel. It stores user-defined rules and uses them to scan flat ascii or tab-delimited text files of clinical laboratory test results downloaded from laboratory information systems or entered manually. The rules identify and assess the persistence of simple, clinically meaningful temporal patterns in the test results, such as increasing or decreasing trends, multiple values out of defined ranges, defined testing frequencies, and defined levels of variability in results. "Found" patients can be displayed graphically or graphical reports may be printed, and a statistical summary of rule performance is available. LabScanner is expected to be useful for quality assurance studies and case finding for followup or teaching, and in the appropriate setting it might prove useful in a clinical pathology consult service. LabScanner is available free of charge to the Laboratory Medicine community for experimentation and testing.

Development release 9 (March 2001) adds the ability to manually enter and edit patient and event data and open rules and archive files by dragging and dropping them on the LabScanner icon (and double-clicking them on the Mac). A bug that prevented creating new rules files was fixed. Windows printing was improved in release 9e.
