Abstract
Objective The comparability of serum results of different biochemical detecting system were studied through the method of comparison and bias estimation between Hitachi 7170 and Olympus AU1000.Methods According to the profile NCCLS EP9-A2, two different biochemical testing system,Hitachi 7170(comparison method) and Olympus AU1000(laboratory method),were used respectively to test 16 serological items to obtain the correlation coefficient and the linear equation, and the system bias % at the level of medical decision were calculated.The comparability of different biochemical testing system was judged according to half of the clinical laboratory improvement amendment 88(CLIA`88) 1/2 of the total errors is allowed.Results The testing results of the different biochemical testing system had a great correlation, All correlation coefficients of 16 items were greater than 0.975. The system bias of ALB and UA at a level of medical decision were not acceptable , and the rest could be accepted.Conclusion If the same item is tested in more than two different systems,it is necessary to judge clinical acceptability by the method of comparison and bias evaluation so as to insure the comparability.关键词
