摘　　要：目的评价不同便携式血糖仪（POCT）的性能,了解其测定全血葡萄糖（venous blood glucose,VBG）与生化分析仪检测血浆葡萄糖（Venous plasma glucose VPG）结果的差异。方法用新换肝素钠抗凝全血对不同仪器精密度试验、与生化仪比对试验、可报告范围进行测定,结果使用SPSS10.0统计软件进行统计分析。结果 Sure-Step血糖仪、Accu-Chek Active血糖仪、ONE Touch血糖仪批内CV%分别是2.36%~2.54%、1.06%~1.25%、4.20%~4.66%,与生化仪（AU5400）回归方程为Y=1.029 9X＋0.1789、Y=0.861 1X＋0.527 6、Y=0.926 7X-0.069 7。在医学决定水平处与目标检测系统比较结果差异小于20%。结论不同POCT血糖仪间及其与生化分析仪检测血糖结果的差异显著,POCT可作为血糖检测的筛选,但不能替代生化分析仪血糖测定。Objective To evaluate the capability of different POCT glucose meters and to understand the difference between the venous blood glucose results by POCT glucose meters and the blood glucose results tested by biochemical analyzer.Methods The accuracy,reportable range,comparison with biochemical analyzer were detected by the different instruments with heparin whole blood.All statistical analyses were performed with SPSS version 11.0 statistical software.Results The within-CV% of Sure-Step,Accu-Chek Active,ONE Touch POCT glucose meters were 2.36%-2.54%,1.06%-1.25%,4.20%-4.66% respectively.The regression equations with biochemical analyzer（AU5400） were Y=1.029 9X＋0.178 9,Y= 0.861 1X＋0.527 6,Y=0.926 7X-0.069 7 respectively.In the medical decision level,the differences from comparison with the target detection systems was 20%.Conclusion There is significant differences between different POCT glucose meters and blood glucose and biochemical analysis of the results detected.POCT glucose testing method can be used as the selection,but not a substitute for blood glucose measurement by biochemical analyzer.
