1.1 本指南涵盖了用于定性和定量分析的缉获药物抽样的最低考虑因素。 1.2 本指南不能取代通过适当教育、培训和经验获得的知识、技能或能力，应与良好的专业判断结合使用。 ====意义和用途====== 3.1 本指南提供了缉获药物提交的抽样信息。 3.2 本指南中抽样的主要目的是通过检查一部分人口来回答有关人口的相关问题。例如: 人口的净重是多少？ 在给定的置信水平下，人口单位的哪一部分可以说包含给定的药物？ 3.3 通过制定采样策略和实施适当的采样方案，如所示 图1 ，实验室将尽可能减少所需分析测定的总数，同时确保满足所有相关的法律和科学要求。

1.1 This guide covers minimum considerations for sampling of seized drugs for qualitative and quantitative analysis. 1.2 This guide cannot replace knowledge, skill, or ability acquired through appropriate education, training, and experience and should be used in conjunction with sound professional judgment. ====== Significance And Use ====== 3.1 This guide provides information for the sampling of seized-drug submissions. 3.2 The principal purpose of sampling in the context of this guide is to answer relevant questions about a population by examination of a portion of the population. For example: What is the net weight of the population? What portion of the units of a population can be said to contain a given drug at a given level of confidence? 3.3 By developing a sampling strategy and implementing appropriate sampling schemes, as illustrated in Fig. 1 , a laboratory will minimize the total number of required analytical determinations, while ensuring that all relevant legal and scientific requirements are met.
