Contrastive Experiments of automatic biochemical analyzer on glucose

Objective:Comparing the glucose test results of Siemens Dimension Xpand automatic biochemical analyzer and domestic Dirui CS-600 automatic biochemical analyzer according to the NCCLS EP9-A file,to explore the comparability for blood glucose test of the two instruments.Methods:We took Diri CS-600 automatic biochemical analyzer as reference instrument,and Siemens Dimension Xpand automatic biochemical analyzer as a test one.Fresh serum selected were tested by the two types of instruments everyday,obtain the correlation coefficient and regression equation of Y=bx+a by the statistical software from the test results,with USA amendment clinical laboratory(CLLA,88) provisions of 1/2 EQA(external quality assessment) permissible error as the standard,to judge the comparability of test results of the two instruments.Results:Differences between the two instruments test of blood glucose was not statistically significant(r = 0.9997,P 0.975).Conclusion:Blood glucose test results of the two instruments have good comparability.
