| Abstract |
COVID-19 is determined by detection of SARS-CoV-2 gene with reverse-transcription PCR (RT-PCR) in routine clinical practice. A new POCT RT-PCR test for detection of SARS-CoV-2 called Smart Gene kit (SG test) was launched by MIZUHO MEDY Co., Ltd in Japan in August 2020. The SG test is a method that enables gene detection with a simple one-step operation, and is a gene detection method based on the quenching probe method. The aim of this study was to verified basic analytical of SG test, used 25 samples of nasopharyngeal swabs cryopreserved with virus transport medium. The comparison method was measured by quantitative one-step RT-PCR (RT-qPCR). The comparison results were 100% sensitivity (10/10), 100% specificity (15/15), and 100% overall concordance (25/25). In this study, the minimum detection concentration of the SG test was 6.41 copies/5 μL. From this result, it was judged that the SG test has sufficient performance as a SARS-CoV-2 genetic test method. Because the SG test can be operated simple one step and easily, it will be possible to perform the genetic test of COVID-19 in a wide range of medical sites such as clinics and core hospitals. There is a shortage of PCR tests in Japan, but the SG test could be a key point to overcome this. |
