Background : By operating 3 same models of Automated Chemisπy Analyzer(Olympus AU560. Japan) and tested results and values from each Analyzer, we`` d like to evaluate each analyzer’s accuracy, precision, linearity, correlations and etc, to report its value.Methods : By using Central Blood Center’s Automated Chemistry Analyzer, Olympus system reagent N(control serum level 1 QDCα)()3 LOT No 014, Olympus AU560’s company’s standard material) and Olympus system reagent P(control serum level 2 QDC0003 LOT No 014) to measure Accuracy. To measure precision, we used Pooling Serum on divided blood donor’s samples as low, medium and high concentration also diluting low and high concentrated samples by stages to measure Linearity. By meauring samples with each Analyzer over and over, we analyzed difference between Analyzers. Result In Accuracy study, all of resu1ts showed in standard value of ALT, but in between-run of Precision study, there were different CES resu1t values between low(19.84- 22.33 IU/L) and high(142.86-148.47 IU/L) concentrated samples from different analyzes and for medium(55.19-57.64 IU/L) concentrated samples there were no difference resu1t values between analyzes. In within-run, except second analyzer’s high concentrated sample, there were no difference between am and pm’s result values. In Linearity, samples, which can be measured, showed good Linearity(R2=0.998). In difference between Analyzers, the coefficient of correlation in 3 analyzes was more than 0.986 which was good result. Conclusions All 3 of AU-560 Automated Chemistry Analyzers showed satisfactoη Accuracy, Precision, Linearity and difference between analyzers had g∞d correlation, therefore it shows the equipments are well managed. But in between-run of Precision study, we found that to manage equipments well, the matters that relate to results of test, such as men, machine, methcxl, measurement, material, milieu and etc have to be comprehended all the time, also matters must be satisfied and need scrupulous care of management..
