Redundant thyroid laboratory diagnostic modules in laboratory information system--a way to improve the performance

In this paper, we introduced an idea of using redundant thyroid laboratory diagnostic modules integrated in laboratory information system. The first module was based on decision tree which was the result of Assistant algorithm applied to thyroid laboratory test results. Instead of improving decision rules, the "second opinion" module was designed based on Spad-S software. Diagnosis obtained with both modules were compared with results before introducing the "second opinion" module. From the first results it was clear that introducing the "second opinion" module decreased the number of misclassified records from the first module. With three or more modules, the final diagnosis could be obtained by voting or more complex procedures.
