New test kits for coronavirus approved in China - Xinhua

Jan 30, 2020 · Helped by an automatic nucleic acid extractor and a mobile molecular diagnostic platform developed by Sansure Biotech, the kits can generate test results in 30 minutes. The NMPA approved four new products for testing the new coronavirus on Jan. 26. Recent advances and perspectives of nucleic acid detection Apr 01, 2020 · The rapid and accurate detection of coronavirus is therefore becoming increasingly important. With the advance in molecular biology technology, nucleic acid detection methods have developed rapidly and become a revolutionary technology for virus detection. Recent progress on the diagnosis of 2019 Novel Coronavirus May 12, 2020 · In conclusion, nucleic acidbased methods are sensitive, but prone to falsepositive. The sensitivity of the antibodybased method is slightly lower, but the accuracy is higher. Therefore, it is suggested that the two methods should be combined to improve the detection accuracy of COVID19.

The Sampling Locations are Closely Related to the Positive

The Sampling Locations are Closely Related to the Positive Rate of Novel Coronavirus Nucleic Acid Detection Clin Lab. 2020 Jun 1;66(6). doi:10.7754/Clin.Lab.2020.200431. Authors Daming Wang, The impacts of viral inactivating methods on quantitative The treatment of nasopharyngeal swab specimens using mentioned four inactivated methods had no significant effect on the subsequent detection of the new COVID-19 nucleic acid test. Lab test-persons can flexibly adopt pre-inactivation methods to ensure the accuracy of virus nucleic acid test results, cobas® SARS-CoV-2 & Influenza A/B AssayThe cobas ® SARS-CoV-2 & Influenza A/B Nucleic acid test for use on the cobas ® Liat ® System (cobas ® SARS-CoV-2 & Influenza A/B) is an automated multiplex real-time RT-PCR assay intended for the simultaneous rapid in vitro qualitative detection and differentiation of SARS-CoV-2, influenza A, and influenza B virus RNA in healthcare provider-collected nasopharyngeal and nasal swabs, and
