摘要
目的探讨血液样品检测时间对血液样品中乙醇含量检测结果的影响。方法志愿者饮酒后2h,分别用6种不同种类的采血管采集志愿者血液样品,置4℃冰箱中冷藏保存。分别在第1、3、5、7、9、12、15天用顶空气相色谱法检测血液样品中乙醇含量。结果用同种类采血管采集的血液样品,在不同时间进行检测,血液样品中乙醇含量检测结果基本一致。结论司法实践酒后驾驶认定中应采用真空采血管(抗凝管)采集驾驶员血液样品。血液样品在冷藏条件下,检测时间对乙醇含量无明显影响。
Objective To probe into the effect of detection time on determining the alcohol content in blood samples.Methods The blood samples,collected at2hours after the volunteers drank alcohol,were stored in six different types of disposable vacuum blood collection tubes kept under4?C in refrigerator.The alcohol was determined of its concentration in blood sample by headspace gas chromatography on the1st,3rd,5th,7th,9th,12th,15th day,respectively.Results It was shown that the almost equal alcohol concentrations were obtained from the same one blood sample kept in type-same tubes regardless of the different detection time.Conclusions One suggestion can be made that a disposable vacuum blood-collection tube(anticoagulant tube)should be used to load the blood sample collected from a driver who is suspected of drinking alcohol.The detection time has no signifi cant effect on the ethanol content in the blood sample stored under4℃.
