<p>Coronavirus disease COVID-19, caused by Severe Acute Respiratory Syndrome Corona Virus-2 (SARS-CoV2), is highly contagious and has been a pandemic since March 2020. The SARS-CoV-2 is an enveloped, single-stranded, positive-sense RNA viruswhich spreadsthrough air droplets by sneezing and coughing from affected person. The diagnosis of the COVID-19 remains a challenge to the scientists since the genome of the SARS-CoV-2 was novel and varying. Various studies have reported the validated procedures for sampling and the detection method of SARS-CoV-2. This mini-review provides a brief introduction of the SARS-CoV-2 features and the current knowledge for the recommended COVID19 detection methods including sampling procedures and real time SARS-CoV-2 genome detection.</p>

ABSTRACT In early March 2020, the University of Washington Medical Center clinical virology laboratory became one of the first clinical laboratories to offer testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). When we first began test development in mid-January, neither of us believed there would be more than 2 million confirmed SARS-CoV-2 infections nationwide or that we would have performed more than 150,000 real-time PCR (RT-PCR) tests, with many more to come. This article will be a chronological summary of how we rapidly validated tests for SARS-CoV-2, increased our testing capacity, and addressed the many problems that came up along the way.

AbstractCDC protocol for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) include 3 targets for detection (N1, N2 and RP) labelled with FAM so 3 PCR reactions are required per sample. We developed a triplex, real-time reverse transcription PCR for SARS-CoV-2 that maintained clinical performance compared with CDC singleplex assay. This protocol could speed up detection and save reagents during current SARS-CoV-2 testing supplies shortage.

Abstract We enrolled 91 consecutive inpatients with COVID-19 at 6 hospitals in Toronto, Canada, and tested 1 nasopharyngeal swab/saliva sample pair from each patient using real-time RT-PCR for severe acute respiratory syndrome coronavirus 2. Sensitivity was 89% for nasopharyngeal swabs and 72% for saliva (P = .02). Difference in sensitivity was greatest for sample pairs collected later in illness.
