摘要由于引发呼吸道感染的病原体种类繁多且感染症状接近，新型冠状病毒肺炎需要与其他常见感染相鉴别。尽早对呼吸道感染病原体进行全面的检测和准确的鉴别，对于疾病的早期诊断、治疗以及监控都有十分重要的意义。多病原联合检测可快速准确地鉴别感染病原体，为临床提供迅速可靠的实验室诊断依据。本文结合相关新近研究成果，阐释多病原联合检测在新型冠状病毒肺炎诊断中的应用现状与发展。

abstractsDue to the wide variety of pathogens causing respiratory tract infection and the close symptoms, coronavirus disease 2019 (COVID-19) needs to be differentiated from other common infections. Early comprehensive detection and accurate identification of respiratory infection pathogens is of great value for early diagnosis, curative effect, as well as monitor of the diseases. Combined detection of multiple pathogens can quickly and accurately detect and distinguish the pathogens, then provide rapid and reliable laboratory diagnostic basis for further treatment. This article elaborates the application and development of multiplex detection assay in the diagnosis of COVID-19 according to the recent research.
