By operating 3 same models of Automated Chemistry 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. By using Central Blood Center’s Automated Chemistry Analyzer, Olympus system reagent N(control serum level 1 QDC0003 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 measuring samples with each Analyzer over and over, we analyzed difference between Analyzers. In Accuracy study, all of results showed in standard value of ALT, but in between-run of Precision study, there were different CES result 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 result 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 morethan 0.986 which was good result. All 3 of AU-560 Automated Chemistry Analyzers showed satisfactory Accuracy, Precision, Linearity and difference between analyzers had good correlation, therefore it shows the equipments are well managed. But in between-run of Precision study, we found that to manage equipments well, thematters 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.
