16台便携式血糖仪与生化分析仪检测血糖结果对比分析

Comparative Analysis of Blood Glucose Testing Results of 16 Portable Blood Glucose Meter and Biochemical Analyzer

目的通过与生化仪血糖检测结果对比分析,评估便携式血糖仪的准确性和精确度。方法选取本院16台德国罗氏血糖仪,检测50份涵盖低中高不同浓度的血糖水平,与生化仪对比,计算偏差及变异系数,评估便携式血糖仪的准确性及精确度。结果 16台罗氏血糖仪中3台精密度不合格,4台准确度不合格,根据回归分析结果,证实4台不合格,不合格率为25.0%。结论加强便携式血糖仪与生化仪的对比校正试验,是保证便携式血糖仪检验质量的重要措施。

Objectives To assess the accuracy and precision of the portable blood glucose meter by comparative analysis of levels of blood glucose with biochemical analyzer and portable blood glucose meter.Methods 50 covering with high concentration and low sugar in the blood specimens were detected with a total of 16 sets of Germany Roche glucose meter selected and biochemical analyzer in our hospital.The deviation and coefficient of variation were compared between two methods.The accuracy and precision of the portable blood glucose meter were assessed.Results About the precision 3sets were not qualified in 16 Roche glucose meters,while about the accuracy 4sets were not qualified.According to the results of regression analysis,4sets were confirmed unqualified.The unqualified rate was 25%.Conclusions Enhancing Contrast and correction test of portable blood glucose meter and biochemical analyzer is an important measure to ensure the quality of the portable blood glucose meter test.
