To assess the practicability (usability and satisfaction) and analytical performances of the VitaPCR™ SARS-CoV-2 Assay (Credo Diagnostics Biomedical Pte. Ltd.), a rapid point-of-care nucleic acid amplification test (NAAT), by reference to real-time reverse-transcription polymerase chain reaction (rRT-PCR) for respiratory viruses. The practicability of the VitaPCR™ Assay and Instrument was assessed from usability evaluation and a satisfaction questionnaire. Nasopharyngeal swabs were collected from 239 patients with coronavirus disease 2019 (COVID-19)-like illness during the second epidemic wave, in Paris, France. Overall, the usability of the VitaPCR™ Instrument was high. The satisfaction questionnaire indicated a high appreciation of the VitaPCR™ NAAT mainly for the short duration of analysis in only 20 min. A total of 140 and 99 samples were positive and negative for SARS-CoV-2 RNA by rRT-PCR, respectively. In the event of significant viral load (i.e., N gene C values 33), the platform's analytical performances dropped significantly, with lower sensitivity, concordance, and accuracy, while its specificity remained high. The VitaPCR™ SARS-CoV-2 Assay is an accurate rapid point-of-care NAAT, suitable for clinical practice for the rapid diagnosis of COVID-19, especially in patients with COVID-19-suspected symptoms.
评估 VitaPCR™ SARS-CoV-2 检测试剂盒(Credo 诊断生物医学私人有限公司)的实用性(可用性和满意度)和分析性能,该试剂盒是一种快速即时检测的核酸扩增检测(NAAT),以实时逆转录聚合酶链反应(rRT-PCR)作为呼吸道病毒检测的参考方法。 VitaPCR™ 检测试剂盒和仪器的实用性通过可用性评估和满意度问卷进行评估。从法国巴黎第二波 COVID-19 疫情期间患有类似 COVID-19 疾病的 239 名患者中采集鼻咽拭子。总体而言, VitaPCR™ 仪器的可用性较高。满意度问卷表明,VitaPCR™ NAAT 主要因其仅 20 分钟的分析时间短而受到高度评价。rRT-PCR 检测分别有 140 份和 99 份样本的 SARS-CoV-2 RNA 呈阳性和阴性。在病毒载量显著升高(即 N 基因 C 值 33)的情况下,该平台的分析性能显著下降,敏感性、一致性和准确性降低,而特异性仍然很高。 VitaPCR™ SARS-CoV-2 检测试剂盒是一种准确的快速即时检测的 NAAT,适用于 COVID-19 的快速临床诊断,特别是对有 COVID-19 疑似症状的患者。
