对COVID-19活动性感染进行快速准确的实验室诊断是大流行控制的基石之一。由于市场上有无数的测试,在正确的临床场景中使用正确的标本类型和实验室测试技术对非专业人员来说可能是具有挑战性的。在这篇简短的综述中,我们将讨论不同上呼吸道和下呼吸道标本的诊断性能差异,以及血液和粪便标本的作用。分析核酸扩增检测、抗原检测、抗体检测、即时检测等实验室检测技术的性能特点。最后,将讨论病毒复制和抗体产生的动力学,以及结合临床情况的实验室结果解释。
Rapid and accurate laboratory diagnosis of active COVID-19 infection is one of the cornerstones of pandemic control. With the myriad of tests available in the market, the use of correct specimen type and laboratory-testing technique in the right clinical scenario could be challenging for non-specialists. In this mini-review, we will discuss the difference in diagnostic performance for different upper and lower respiratory tract specimens, and the role of blood and fecal specimens. We will analyze the performance characteristics of laboratory testing techniques of nucleic acid amplification tests, antigen detection tests, antibody detection tests, and point-of-care tests. Finally, the dynamics of viral replication and antibody production, and laboratory results interpretation in conjunction with clinical scenarios will be discussed.
