研究目的:

本研究为一项探索性诊断试验,旨在开发并验证一种基于呼出气冷凝液(EBC)的无创电化学传感平台(EBCatch),用于快速检测呼吸道病毒,并系统评价其诊断准确性,重点评估其在无症状感染阶段的检测性能。 主要研究目标: 系统评价EBCatch系统在呼吸道病毒检测中的诊断准确性,以qRT-PCR结果为参考标准,计算其检测的灵敏度与特异度。 次要研究目标: 1. 评估EBCatch系统在无症状感染阶段的检测能力。 2. 分析EBCatch检测结果与病毒载量(Ct值)的相关性。 3. 评估该检测方法的用户体验与操作便捷性。 探索性目的: 探索EBCatch检测信号与患者临床症状严重程度之间的潜在关联。  

Objectives of Study:

This study is an exploratory diagnostic trial aimed at developing and validating an inhaled non-invasive electrochemical sensing platform (EBCatch) based on exhaled breath condensate (EBC), for the rapid detection of respiratory viruses, and systematically evaluating its diagnostic accuracy, with a particular focus on assessing its detection performance during the asymptomatic infection stage.Main research objective:To conduct a systematic evaluation of the diagnostic accuracy of the EBCatch system in the detection of respiratory viruses, using the results of qRT-PCR as the reference standard, and to calculate its sensitivity and specificity. Secondary research objectives:1. Evaluate the detection capability of the EBCatch system during the asymptomatic infection stage.2. Analyze the correlation between EBCatch test results and viral load (Ct value).3. Assess the user experience and operational convenience of this detection method. Exploratory purpose:To explore the potential association between the EBCatch detection signals and the severity of patients' clinical symptoms.
