在...之前
例1
Prior to conducting clinical trials for a new drug, extensive preclinical studies, including toxicity tests and pharmacokinetic profiling in animal models, must be completed to ensure safety and efficacy.
在进行新药临床试验之前，必须完成广泛的临床前研究，包括在动物模型中进行毒性和药代动力学分析，以确保药物的安全性和有效性。
例2
Prior to diagnosing gestational diabetes, glucose tolerance testing is conducted during the second trimester to identify impaired glucose metabolism and implement timely interventions.
在诊断妊娠糖尿病之前，通常会在第二孕期进行葡萄糖耐量测试，以识别葡萄糖代谢异常并实施及时干预。
· glucose tolerance 糖耐量
· trimester n.（怀孕期）三个月
——trimester 表示“妊娠期这个特定的场景中的三个月”，所以会看到 first trimester、second trimester。
例3
In the treatment of acute coronary syndrome, a detailed risk assessment and stabilization of hemodynamics are critical steps prior to performing invasive procedures such as percutaneous coronary intervention.
在治疗急性冠脉综合征时，进行详细的风险评估并稳定血流动力学是经皮冠状动脉介入治疗等侵入性操作之前的关键步骤。
例4
Prior to initiating targeted therapy for oncologic conditions, genomic profiling of the tumor is often necessary to identify actionable mutations and ensure the chosen treatment aligns with the molecular characteristics of the tumor.
在为肿瘤患者启动靶向治疗之前，通常需要进行肿瘤基因组分析，以识别可靶向突变并确保所选治疗方案与肿瘤的分子特征相符。
