| ［摘要］ 由于传统呼吸道病原体检测手段的限制，导致临床诊断难、治疗用药难。呼吸道感染多联检产品时效性高，可及早识别感染，并指导抗感染药物的合理使用。各种便携式（快速）诊断技术产品发展迅速，临床应用前景广阔。宏基因组二代测序技术（mNGS）对呼吸道感染病原体的检测覆盖面广、信息量大，对呼吸道病原体的早期发现，特别是新发传染病的病原体快速诊断，起到非常重要的作用。基于规律间隔成簇短回文重复序列（CRISPR）的核酸检测技术、三代测序技术及基因芯片技术等快速检测新技术为呼吸道病原体的诊断开辟了新的方向。 |

| Abstract: |
| ［Abstract］ The limitations of traditional detection means of respiratory pathogens make clinical diagnosis and therapeutic medication difficult. The multiple joint detection products have high timeliness for respiratory tract infection. They can identify infections as soon as possible, and guide the rational use of anti-infective drugs. A variety of portable(rapid) diagnostic technology products are developing rapidly and have broad prospects for clinical application. The detection of pathogens in respiratory tract infection by metagenomics next-generation sequencing(mNGS) is extensive and informative, which plays a very important role in the early detection of respiratory pathogens, especially in the rapid diagnosis of a novel infectious disease. New rapid detection technologies such as clustered regularly interspaced short palindromic repeats(CRISPR)-based nucleic acid assay, third-generation sequencing technology and gene chip test have showed new detection directions for the diagnosis of respiratory pathogens. |
