The COVID-19 pandemic is expanding at an unprecedented rate. As a result, diagnostic services are stretched to their limit, and there is a clear need for the provision of additional diagnostic capacity. Academic laboratories, many of which are closed due to governmental lockdowns, may be in a position to support local screening capacity by adapting their current laboratory practices. Here, we describe the process of developing a SARS-Cov2 diagnostic workflow in a conventional academic Containment Level 2 laboratory. Our outline includes simple SARS-Cov2 deactivation upon contact, the method for a quantitative real-time reverse transcriptase PCR detecting SARS-Cov2, a description of process establishment and validation, and some considerations for establishing a similar workflow elsewhere. This was achieved under challenging circumstances through the collaborative efforts of scientists, clinical staff, and diagnostic staff to mitigate to the ongoing crisis. Within 14 days, we created a validated COVID-19 diagnostics service for healthcare workers in our local hospital. The described methods are not exhaustive, but we hope may offer support to other academic groups aiming to set up something comparable in a short time frame.
新冠疫情正在以前所未有的速度蔓延。因此,诊断服务已不堪重负,显然需要增加诊断能力。许多学术实验室因政府封锁而关闭,或许可以通过调整现有实验室操作来支持当地的筛查能力。在此,我们描述了在传统的学术二级生物安全实验室中开发新冠病毒诊断工作流程的过程。我们的概述包括接触后对新冠病毒的简单灭活、定量实时逆转录聚合酶链反应检测新冠病毒的方法、流程建立与验证的描述,以及在其他地方建立类似工作流程的一些注意事项。这是在具有挑战性的情况下,通过科学家、临床工作人员和诊断人员的共同努力实现的,以缓解当前的危机。在14天内,我们为当地医院的医护人员创建了一项经过验证的新冠诊断服务。所描述的方法并不详尽,但我们希望能为其他旨在在短时间内建立类似服务的学术团体提供支持。
