摘要
体内毒品检验所涉及不同生物检材有不同的特点,如检测时间窗不同,有无损伤、采集方式和保存方式等不同,应根据检验目标、检材特点、提取场合等采集适宜的生物检材,选用适宜的检验技术。免疫分析技术和色质联用技术在法庭科学领域中应用广泛,是检验体内毒品的两个重要技术手段,分别起到了初筛和确证的作用。与检验体内毒品相关的法规和行业标准也有了较大的进展,不仅统一了检验结果的阴性或阳性判定标准,而且为出具检验报告或鉴定报告提供了法律保障。本文综述了近年来各类生物检材的体内代谢和采集等特点,以及对免疫分析技术的应用现状及色-质联用技术的发展进行分析,最后还探讨了行业标准、行业规范对现有免疫分析技术和色质联用技术的指导规范,以期为公检法司技术人员在体内毒品检验鉴定中提供参考。
Different biological test materials involved in drug detection in vivo have different characteristics, such as different detection time window, whether there is damage, collection method and preservation method, etc. appropriate biological samples should be collected according to the detection target, the characteristics of samples, extraction spot, etc.and appropriate detection techniques should be selected. Immunoassay screening test and chromatography-mass spectrometry detection are widely used in forensic science. They are two important techniques to detect drugs in vivo and play the role of screening and a confirmation respectively. Laws and regulations and industrial standards related to drug detecting in vivo have also made great progress, which not only unifies the criteria for determining negative and positive test results, but also provides legal guarantee for issuing test reports and identification reports. This paper reviewed the characteristics of the metabolism and collection and preservation of various biological samples in recent years. and the application status of immune analysis technology and the development of chromatography-mass spectrometry were also analyzed. Finally, the industrial standards and codes about the immunoassay technology and chromatography-mass spectrometry technology were discussed, in order to provide reference for police in the detection and identification of drugs in vivo.
