In the current pandemic of SARS-CoV-2, rapid identification of infected individuals is crucial for management and control of the outbreak. However, transport of samples, sample processing and RT-qPCR analysis in laboratories are time-consuming. Here we present a prototype of a novel nucleic acid-based test format - pulse controlled amplification - that allows detection of SARS-CoV-2 directly from up to eight swab samples simultaneously without the need for RNA extraction within 25 min with a sensitivity of 100 % for samples with a viral load of ≥ 1.6 × 10e3 copies/μl This new principle might pave the way to rapid and sensitive point of care testing.
在当前的 SARS-CoV-2 大流行中,快速识别感染者对于疫情的管理和控制至关重要。然而,样本的运输、样本处理和实验室中的 RT-qPCR 分析都很耗时。在这里,我们展示了一种新型基于核酸的测试格式——脉冲控制扩增的原型,它允许直接从多达八个拭子样本同时进行 SARS-CoV-2 的检测,而无需在 25 分钟内进行 RNA 提取,对于病毒载量≥1.6×10e3 拷贝/μl 的样本,其灵敏度为 100%。这一新原理可能为快速、灵敏的即时检测铺平道路。
