Reverse transcriptase loop-mediated isothermal amplification (RT-LAMP) is one of the time-saving, accurate, and cost-effective alternative methods to real-time polymerase chain reaction (RT-PCR). This study aimed to identify the robustness of a colorimetric RT-LAMP assay kit that we developed, detecting SARS-COV-2 viral RNA within 30 minutes using a primer set special to the N gene against RT-PCR, the gold standard.
Both symptomatic and asymptomatic subjects were included from a single university hospital and the status of both RT-PCR and RT-LAMP assay results were compared, and the consistency of these two assays was analyzed.
We showed that the RT-LAMP and RT-PCR assay results confirmed 90% consistency. When we consider the epidemiologic, clinical, and radiologic evaluation, the consistency reached 97%.
The results revealed that the colorimetric RT-LAMP assay was efficient, robust, and rapid to be used as in vitro diagnostic tool to display competitiveness compared with RT-PCR.
逆转录环介导等温扩增技术(RT-LAMP)是一种省时、准确且经济高效的替代实时聚合酶链反应(RT-PCR)的方法。本研究旨在鉴定我们开发的一种比色RT-LAMP检测试剂盒的稳健性,该试剂盒使用针对N基因的引物组,在30分钟内检测严重急性呼吸综合征冠状病毒2(SARS-CoV-2)病毒RNA,并与金标准RT-PCR进行比较。
纳入来自一家大学医院的有症状和无症状受试者,比较RT-PCR和RT-LAMP检测结果的状况,并分析这两种检测方法的一致性。
我们发现RT-LAMP和RT-PCR检测结果的一致性为90%。当我们考虑流行病学、临床和影像学评估时,一致性达到97%。
结果表明,与RT-PCR相比,比色RT-LAMP检测作为一种体外诊断工具,高效、稳健且快速,具有竞争力。
