Abstract:
Objective To grasp bilirubin in the quality control serum and calibration items in the same batch the variation law of the designed to ensure that the test quality and the use of reasonable quality control serum and calibration items ,control testing cost .Methods laboratories use The double level quality control serum and calibration items after dilution is divided into five groups ,with automatic biochemical analyzer test for 12 weeks and recorded results of TBIL ,DBIL .use SPSS 17 .0 to calculate the mean ,standard deviation ,coefficient of variation ,Normal distribution analysis and make the results trend line chart to observe any changes .Results RANDOX normal concentration quality control serum TBIL and DBIL values variation RCV% 26 .0% ,48 .2% , more than CLIA bilirubin projects allow 1/3 of the total error value(6 .67% ) .Normal distribution test ,P value was 0 .006 ,0 .012 , less than 0 .05 ,do not obey the normal distribution ,test results line chart is on the decline .LEADMAN high concentration quality control serum and bilirubin calibration items TBIL and DBIL variation RCV% <6 .67% ,normal distribution test all P>0 .05 ,obey the normal distribution ,test results no trend line chart .Conclusion Through the experiment observation to the quality control ser‐um and calibration items bilirubin in the variation law of 12 weeks .Experimenter can be used according to the actual situation to ad‐just ,not only to ensure the quality of the bilirubin test ,and to get the most out of the quality control serum and calibration items use efficiency ,reduce the test cost .
