Point-of-care (POC) tests are in high demand in order to facilitate rapid care decisions for patients suspected of SARS-CoV-2. We conducted a clinical validation study of the Cue Health POC nucleic acid amplification test (NAAT) using the Cue lower nasal swab, compared to a reference NAAT using standard nasopharyngeal swab, in 292 symptomatic and asymptomatic outpatients for SARS-CoV-2 detection in a community drive through collection setting. Positive percent agreement between Cue COVID-19 and reference SARS-CoV-2 test was 91.7% (22 of 24); or 95.7% (22 of 23) when one patient with no tie-breaker method was excluded. Negative percent agreement was 98.4% (239 of 243), and there were 25 (8.6%) invalid or canceled results. The Cue COVID-19 test demonstrated very good positive and negative percent agreement with central laboratory tests and will be useful in settings where accurate POC testing is needed to facilitate management of patients suspected of COVID-19.
为了方便疑似 SARS-CoV-2 患者快速做出治疗决策,即时检测(POC)需求很高。我们使用 Cue 下鼻拭子,对 Cue Health POC 核酸扩增检测(NAAT)进行了临床验证研究,该检测与使用标准鼻咽拭子的参考 NAAT 相比,在社区驾车采集点对 292 名有症状和无症状的门诊患者进行 SARS-CoV-2 检测。Cue COVID-19 与参考 SARS-CoV-2 检测之间的阳性百分比符合率为 91.7%(24 例中有 22 例);排除无判定方法的一位患者后,阳性百分比符合率为 95.7%(23 例中有 22 例)。阴性百分比符合率为 98.4%(239 例中有 239 例),有 25 例(8.6%)结果无效或被取消。Cue COVID-19 检测与中心实验室检测具有非常好的阳性和阴性百分比符合率,将有助于在需要准确的 POC 检测以方便管理疑似 COVID-19 患者的情况下使用。
