| Abstract;There are a lots of methods of controlling quality of laboratory test results. The internal quality control by measuring control materials is the fundamental strategy. Plots of the results allow technologies to view data on a day-by-day basis and to find analytical errors. The use of patient data instead of control material is another method for the internal quality control. Daily means of patients' data are useful indicators for detecting systemic errors of automatic analyzers and/or analytical reagents. The second category of the quality control is to find individual errors during specimen acquisition, patient identification, analysis, and so on. The method of cumulative delta check and the multivariate statistics as Mahalanobis' generalized distance are well-known and have widely been introduced in many clinical laboratories. One of the recent topics in the actual zone method, which may be a more powerful tool for the purpose. (author abst.) |
