Early iagnosis of 2019 novel coronavirus(2019-nCoV) infection is the key prevention and control. Al though a positive nucleic acid test result of 2019-nCoV is the "gold standard "for the diagnosis in those suspected patients, its operation is tedious and time-consuming, and the test results are affected by many factors, such the sample quality, the infection site and expression level of the virus. Therefore, the single nucleic acid test can- not meet the requirements for rapid screening and diagnosis during the epidemic. Serum specific antibody is anoth r key evidence for the diagnosis of virus infection. Antibody detection can be used as an important means to assist nucleic acid diagnosis and rapid screening. This review interpreted the characteristics of antibody production, the methods and sensitivity/specificity of antibody testing, analysis of false the combination of the nucleic acid test and antibody detection to promote the establishment and application of the technology of 2019-nCoV serum antibody testing Key words] 2019 novel coronavirus; coronavirus disease 2019; antibody detection: nucleic acid Med J PUMCH, 2020, 11: Epub ahead of print 基金项目:中国医学科学院医学与健康科技创新工程资助项目(2016-12M-1-014) 利益冲突:无协 和 医 学 杂 志 Medical Journal of Peking Union Medical College Hospital 1 基金项目: 中国医学科学院医学与健康科技创新工程资助项目 (2016 ̄12M ̄1 ̄014) 利益冲突: 无 􀅰新型冠状病毒肺炎防控专栏􀅰 新型冠状病毒血清特异性抗体检测技术应用探讨 宁雅婷ꎬ 侯 欣ꎬ 陆旻雅ꎬ 吴 宪ꎬ 李永哲ꎬ 徐英春 中国医学科学院 北京协和医学院 北京协和医院检验科ꎬ 北京 100730 通信作者: 徐英春 电话: 010 ̄69159766ꎬ E ̄mail: xycpumch@ 139.com 【摘要】 2019 年 12 月在武汉暴发的新型冠状病毒肺炎疫情发展迅速ꎬ 早期诊断成为疫情防控的关键ꎮ 2019 新型冠 状病毒 (2019 novel coronavirusꎬ 2019 ̄nCoV) 核酸检测阳性虽是疑似患者确诊的 “金标准”ꎬ 但其操作繁琐、 耗时长ꎬ 检测结果易受标本质量、 病毒感染部位及表达量等众多因素影响ꎬ 因而核酸单项检测不能满足疫情期间对疑似病例快速 筛查的要求ꎮ 血清特异性抗体是诊断病毒感染的另一关键证据ꎬ 抗体协同核酸检测可用于辅助诊断和快速筛查ꎮ 本文从 抗体产生特点、 检测方法及其灵敏度/ 特异度、 假阴性/ 假阳性检测结果分析、 核酸与抗体联合检测等方面进行讨论ꎬ 以 期推动 2019 ̄nCoV 血清抗体检测技术的建立与应用ꎮ 【关键词】 新型冠状病毒ꎻ 新型冠状病毒肺炎ꎻ 抗体检测ꎻ 核酸检测 【中图分类号】 R446 【文献标志码】 A DOI: 10􀆰 3969 / j􀆰 issn􀆰 1674 ̄9081􀆰 20200050 Application of the Technology of Serum Specific Antibody in Detecting 2019 Novel Coronavirus NING Ya ̄tingꎬ HOU Xinꎬ LU Min ̄yaꎬ WU Xianꎬ LI Yong ̄zheꎬ XU Ying ̄chun Department of Clinical Laboratoryꎬ Peking Union Medical College Hospitalꎬ Chinese Academy of Medical Sciences & Peking Union Medical Collegeꎬ Beijing 100730ꎬ China Corresponding author: XU Ying ̄chun Tel: 86 ̄10 ̄69159766ꎬ E ̄mail: xycpumch@ 139.com 【Abstract】 The outbreak of coronavirus disease 2019 in Wuhan in Decemberꎬ 2019 develops rapidly.
