ABSTRACT

Objective According to the comparison and deviation assessment of the part item test results between the OLYMPUS AU640 and BECKMAN AU5821 automatic biochemical analyzer in the laboratory,explore whether the test results between the 2 biochemical analyzers is comparable or not.Methods Reference EPg-A2 file requirements of the American Clinical Laboratory Standardization Committee(NCCLS),test the fresh clinical mixed serum and quality control serum in the 2 equipments respectively,the OLYMPUS AU640 is the reference equipment,the BECKMAN AU5821 is alignment equipment,using regression analysis and paired t test to compare the test results and deviation assessment of the same item,the standard is 1/2 of the total error which the American clinical laboratory improvement amendment (CLIA' 88)allowed,evaluate test results whether is comparable or not.Results Most test results showed good consistency between the 2 biochemical analyzers.Conclusion Through the comparison and deviation assessment in the different biochemical analyzers,the correlation of the same test results can be validated,it is useful to evaluate and correct the equipment,and meet the needs of the clinical.
