We evaluated the sensitivity and specificity of the Biomeme Franklin™ three9 Real-Time PCR Thermocycler and Biomeme SARS-CoV-2 Go-Strips in the detection of SARS-CoV-2. The Biomeme Franklin™ three9 platform is a portable, battery-operated system that could be used in remote settings. We assessed performance of the Biomeme SARS-CoV-2 detection system at a wide range of viral concentrations, examined cross-reactivity of the SARS-CoV-2 Go-Strips against several near-neighbor respiratory pathogens, and evaluated agreement against the BioFire® Respiratory Panel 2.1 in four clinical sample types. Our data indicate the Biomeme Go-Strips can reliably detect SARS-CoV-2 at a concentration of 4.2 × 10 copies/mL. No cross reactivity of the Go-Strips targets was detected against any of the tested near-neighbor respiratory pathogens. Cohen's kappa statistics ranged from 0.68 to 0.92 between results from the Biomeme SARS-CoV-2 Go-Strips and the BioFire® Respiratory Panel 2.1 in all the different sample types. Compared to the BioFire® Respiratory Panel 2.1, the Biomeme SARS-CoV-2 Go-Strips demonstrated statistically significantly lower sensitivity in 3 out of 5 sample types. Overall, our study demonstrates the Biomeme Franklin™ three9 used with the SARS-CoV-2 Go-Strips is an effective system for the detection of SARS-CoV-2 that could potentially be used in a remote or austere environment.
我们评估了Biomeme Franklin™ three9实时荧光定量PCR仪和Biomeme SARS-CoV-2检测试纸条在检测严重急性呼吸综合征冠状病毒2(SARS-CoV-2)方面的敏感性和特异性。Biomeme Franklin™ three9平台是一个便携式、电池供电的系统,可用于偏远地区。我们在广泛的病毒浓度范围内评估了Biomeme SARS-CoV-2检测系统的性能,检测了SARS-CoV-2检测试纸条对几种相近呼吸道病原体的交叉反应性,并在四种临床样本类型中评估了其与BioFire® 呼吸病原体鉴定2.1 Panel检测结果的一致性。我们的数据表明,Biomeme检测试纸条能够可靠地检测浓度为4.2×10拷贝/毫升的SARS-CoV-2。未检测到检测试纸条的靶标与任何测试的相近呼吸道病原体之间存在交叉反应。在所有不同样本类型中,Biomeme SARS-CoV-2检测试纸条与BioFire® 呼吸病原体鉴定2.1 Panel结果之间的Cohen's kappa统计值范围为0.68至0.92。与BioFire® 呼吸病原体鉴定2.1 Panel相比,Biomeme SARS-CoV-2检测试纸条在5种样本类型中的3种中表现出统计学上显著较低的敏感性。总体而言,我们的研究表明,与SARS-CoV-2检测试纸条一起使用的Biomeme Franklin™ three9是一种有效的SARS-CoV-2检测系统,有可能用于偏远或艰苦环境。
