三种仪器检测血糖的对比分析

目的 研究利用血气分析仪与便携式血糖仪以及全自动生化分析仪测定血糖的相关性与偏倚,并探讨其差异.方法 分别用GEM Premier3000血气分析仪、罗氏罗康全型便携式血糖仪及日立7080全自动生化分析仪对40例患者的动脉血液标本进行血糖浓度的检测,对检测结果做统计学处理,观察三者结果差异有无统计学意义,并分析原因.结果 GEM Premier3000血气分析仪、罗氏罗康全型血糖仪与日立7080生化仪测定值间差异均无统计学意义(P>0.05).结论 同一实验室的检测系统应进行方法学对比和结果偏差评估,从而判断其临床可接受性,以保证检验结果的可比性.

Comparison of determination of blood glucose by blood gas analyzer,portable blood glucose meter and automated biochemical analyzer

Objective To explore the correlation,bias and possible differences of the determination of blood glucose concentrations by blood gas analyzer,portable blood glucose meter and automated biochemical analyzer.Methods To analyze the blood glucose concentration of 40 patients＇ blood samples by using GEM Premiere3000 blood gas analyzer,Roche portable blood glucose meter and Hitachi 7080 automated biochemical analyzer respectively.The statistical process was performed on the testing results to determine whether there were significant differences among them and analyzed the causes.Results The testing results from GEM Premiere3000 blood gas analyzer,Roche portable blood glucose meter and Hitachi 7080 automated biochemical analyzer had no significant differences.Conclusion The same laboratory testing system should be performed the methodological comparison and the evaluation of bias to judge its clinical acceptability for ensuring the comparability of test results.
