DNAmix 2021 is a large-scale study conducted to evaluate the extent of consistency and variation among forensic laboratories in the interpretation of DNA mixtures, and to assess the effects of various potential sources of variability. This study utilized a multi-phasic approach designed to collect information about participating laboratories, laboratory policies, and their standard operating procedures (SOPs). It also characterizes the degree of variation in assessments of suitability and number of contributors as well as in comparisons and statistical analyses of DNA mixture profiles. This paper specifically details the study design and the data collected in the first two phases of the study: the and the . We report on the variation in policies and SOPs for 86 forensic laboratories-including information about their DNA workflows, systems, and type of statistics reported. We also provide details regarding various case-scenario specific decisions and the nature of mixture casework for 83 forensic laboratories. The data discussed in this article provide insight into the state of the field for forensic DNA mixture interpretation policies and SOPs at the time of the study (2021-2022).
DNAmix 2021是一项大规模研究，旨在评估法医实验室在解释DNA混合物时的一致性程度和差异，并评估各种潜在变异来源的影响。本研究采用了多阶段方法，旨在收集有关参与实验室、实验室政策及其标准操作程序（SOP）的信息。它还表征了在适用性评估、贡献者数量评估以及DNA混合物图谱的比较和统计分析方面的变异程度。本文具体详细介绍了研究设计以及研究前两个阶段收集的数据：即[此处原文缺失两个阶段的具体内容]。我们报告了86个法医实验室在政策和SOP方面的差异——包括有关其DNA工作流程、系统以及所报告统计类型的信息。我们还提供了83个法医实验室关于各种特定案例场景决策以及混合物案件工作性质的详细信息。本文讨论的数据为研究期间（2021 - 2022年）法医DNA混合物解释政策和SOP的该领域状况提供了见解。
