GM260型便携式血糖仪与AU5821全自动生化分析仪比对分析

摘要

目的:通过对临床使用的GM260型便携式血糖仪(以下简称“便携式血糖仪”)与AU5821全自动生化分析仪(以下简称“全自动生化分析仪”)进行比对,验证便携式血糖仪的准确性,判断其是否适用于临床诊疗需要.方法:选取20份EDTA-K2抗凝的患者样本,对样本和23台便携式血糖仪进行统一编号,每份样本分别在便携式血糖仪和全自动生化分析仪上进行检测,计算2种仪器的偏倚.结果:血糖浓度＜4.2 mmol/L的5个样本,便携式血糖仪与全自动生化分析仪检测结果的最大偏倚为0.47 mmol/L,所有便携式血糖仪检测结果的偏倚均在±0.83 mmol/L的范围内;血糖浓度≥4.2 mmol/L的15个样本,2种仪器检测结果的最大偏倚为18.07％,所有便携式血糖仪检测结果的偏倚均在±20％范围内,符合卫生行业标准.便携式血糖仪检测结果低于全自动生化分析仪检测结果,最大负偏倚达到-13.43％.结论:在选择血糖检测方式的时候,便携式血糖仪只能作为一个筛查仪器,而全自动生化分析仪则是糖尿病诊断的首选检测仪器.%Objective To compare GM260 portable blood glucose meter and AU5821 automatic biochemical analyzer in order to prove the accuracy of GM260 and its applicability for clinical use.Methods Totally 20 pieces of EDTA-K2 anticoagulative specimens and 23 GM260 meters were numbered,and each specimen underwent examinations by both GM260 and AU5821,then the bias between the two kinds of devices was calculated.Results The maximal bias between GM260 and AU5821 was 0.47 mmol/L and all the meters had the bias between-0.83 and 0.83 mmol/L in case of 5 specimens with the glucose concentration less than 4.2 mmol/L;the maximal bias between GM260 and AU5821 was 18.07％ and all the meters had the bias between-20％ and 20％ in case of 15 specimens with the glucose concentration not less than 4.2 mmol/L;the examination results by GM260 all accorded with industrial standard.The results by GM260 were lower than those by AU5821,and the maximal negative deviation was-13.43％.Conclusion Portable blood glucose meter can only be used for screening,and automatic biochemical analyzer is the preferred device for diabetes diagnosis.
