两种不同方法同步检测血清中乙醇浓度的对比分析

Comparison by two methods for determination of ethanol

目的对同一临床实验室检测血液中乙醇含量的不同检测系统进行评估,探讨不同检测系统中乙醇的测定结果是否具有可比性,为临床实验室认可提供参考依据。方法收集2012年7月至2012年12月来我院进行交通事故乙醇鉴定的样品120例。分别用微粒子酶免化学发光法和顶空气相色谱法检测血液中乙醇的含量。用SPSS16.0软件统计处理。结果两种方法间分析具有良好的可比性和相关性,差异没有显著性意义。结论应重视分析不同方法不同仪器间结果的比对工作,确保检验结果的准确性和一致性。

Objective To compare the detection results of ethanol by two different method, to provide the evidence for laboratory accreditation. Methods ethanol content inl20 patients were detected by AXSYM and gas chromatograph. Results The results showed that the blood ethanol content detected by AXSYM and gas chromatograph were in good linear relationship. Conclusion In order to achieve good results, methodology comparison and bias estimation were necessary when using different analyzers to detect the same items.
