The demand for obtaining test results using liquid chromatography-tandem mass spectrometry (LC-MS/MS) for accurate diagnosis in the field of laboratory medicine is expected to increase, but it is still not easy to introduce diagnostic methods using LC-MS/MS into clinical laboratories for many reasons. There are many different methods used to evaluate the performance of LC-MS/MS in clinical laboratories, which have not been standardized to date. Thus, various data have been analyzed and described based on the type of validation method used and the criteria needed to introduce a new test using LC-MS/MS in a clinical laboratory. Relevant data from home and abroad were reviewed to include the minimum number of validation items required and methods of implementation. In general, the items required for a full validation of the quantitative test and various guidelines were used to summarize the following validation items: accuracy, precision, calibration, specificity, ion suppression or improvement, limit of detection, limit of quantification, stability, reference interval, carryover, and dilution integrity. Among these, the first five items mentioned beforehand are essential parameters for LC-MS/MS validation and are presented in numerous guidelines. The other parameters are required for further verification depending on the characteristics of the analysis and the analytes. This recommendation is intended to outline and present the validation methods that should be carried out when introducing new tests in clinical laboratories using LC-MS/MS with reference to the existing guidelines and literature containing expert opinions.
