This article reveals how law and legal interests transform medicine. Drawing on qualitative interviews with medical professionals, this study shows how providers mobilize law and engage in investigatory work as they deliver care. Using the case of drug testing pregnant patients, I examine three mechanisms by which medico-legal hybridity occurs in clinical settings. The first mechanism, clinicalization, describes how forensic tools and methods are cast in clinical terminology, effectively cloaking their forensic intent. In the second, medical professionals informally rank the riskiness of illicit substances using both medical and criminal-legal assessments. The third mechanism describes how gender, race, and class inform forensic decision-making and criminal suspicion in maternal health. The findings show that by straddling both medical and legal domains, medicine conforms to the standards and norms of neither institution while also suspending meaningful rights for patients seeking care.

本文揭示了法律和法律利益如何改变医学。本研究利用对医疗专业人员的定性访谈，展示了提供者在提供护理时如何动员法律并参与调查工作。使用对怀孕患者进行药物测试的案例，我研究了在临床环境中发生法医杂交的三种机制。第一个机制，临床化，描述了取证工具和方法如何在临床术语中使用，有效地掩盖了他们的取证意图。其次，医疗专业人员使用医疗和刑事法律评估对非法物质的风险进行非正式排名。第三种机制描述了性别、种族和阶级如何影响孕产妇健康的法医决策和犯罪嫌疑。
