Abstract
Objective To investigate the glucose testing results correlation between portable blood glucose meter and biochemical analyzer by comparing the testing results of three different modes of portable blood glucose meters and biochemical analyzer. Methods With reference to the protocol of venous sample comparison from < the management and clinical practices of portable blood glucose monitoring device in medical institution (Trail) ), 50 cases of heparin anti-coagulation venous whole blood were collected. Whole blood glucose was measured by glucose meter firstly,and then the remaining samples were cen-trifuged immediately to get plasma. The plasma glucose was tested by biochemical analyzer within 30 minutes. The correlation coefficients and deviations were calculated from the results between three glucose meters and biochemical analyzer and also the relevant analysis was conducted. Results The within-run CV of three glucose meters was between 1. 28% and 4. 87%. The intra-day imprecision of low concentration QC material was s <0.13 mmol/L. The CV of middle and high concentration QC material was between 1. 28% and 4. 87%,which meet the precision requirement of the specification. The results coefficients of these two different testing equipments ( r) were higher than 0. 98. The slope of linear regression equation b>l. 0±0. 05 and for samples which the glucose concentration was between 2. 3 and 4. 2 mmol/L, the percentages of testing results within the acceptable error(±0. 83 mmol/L) were 60%,30% and 80% for Sure Step,Performa and Active blood glucose meter, respectively. While for samples which the glucose concentration was between 4. 6 and 22. 6 mmol/L, the percentage of testing results within the acceptable error was between 95% and 97. 5%. Conclusion Results of three portable glucose meters were all correlated very well with those of biochemical analyser and meet the requirement of the specification. But results of glucose meters were lower than biochemical analyser,generally. The results deviation of glucose meters and biochemical analyser could meet the requirement of the specification only when the glucose concentration was higher than 4. 2 mmol/L, which means biochemical analyzer should be used to re-test the low concentration glucose sample.关键词
