2015年至2016年送检血液乙醇测定结果分析

An Analysis of the Results of Blood Alcohol Concentration Detection from 2015 to 2016

目的:对2015年至2016年送检的人体血液中乙醇含量测定结果进行分析。方法:采用顶空气相色谱法,依据公安部标准GA/T 1073-2013进行血液中乙醇含量测定。结果:两年样品组成比较,差异具有统计学意义(P<0.05),且全血样品数从27.5%上升到38.9%。人体血液乙醇含量测定结果比较,差异具有统计学意义(P<0.05)。无乙醇样品数从53.2%下降到25.8%,乙醇含量80 mg/100 m L以上样品数从43.7%上升到69.4%。平行样品及复核样品比较,差异无统计学意义(P>0.05)。结论:人体血液乙醇测定,样品采集必须规范:全血平行样,并且及时送检,避免人为造成的误差。检测时应按要求进行,保证结果的准确、客观,为执法提供科学的依据。

Objective： To analyze the blood ethanol content of samples sent to the center from 2015 to 2016 in order to provide the basis for the future analysis. Methods： The ethanol content in the blood was detected by headspace-gas chromatography（GC/MS）according to the technical specifications of Judicial Expertise GA/T 1073-2013. Results： The compositions of samples from these two years were compared and it had statistical significance（P〈0.05）. The ratio of whole blood samples increased from 27.5% to 38.9%; the results of blood ethanol detection had statistical significance（P〈0.05）. The ratio of samples without ethanol decreased from 53.2% to25.8%; the ratio of samples with ethanol content greater than 80 mg/100 m L increased from 43.7% to 69.4%. Comparison between parallel samples and review samples did not show significant differences（P〉0.05）. Conclusion： Standardization of blood sample collection is necessary： parallel samples of whole blood need to be collected and sent for detection timely under any circumstances in order to provide accurate results of blood alcohol concentration detection for the judicial process.
