We explore the technical and implementation problems encountered during this early phase in the pandemic, and try to define future directions for the progressive and better use of (syndromic) diagnostics during a possible resurgence of COVID-19 in future global waves or regional outbreaks. In this Review, we summarize the crucial role of diagnostic tests during the first global wave of COVID-19. Hundreds of molecular tests and immunoassays were rapidly developed, albeit many still await clinical validation and formal approval. Under the reissued EUA, the Palmetto Bay, Florida-based company's test may also be used with saliva samples collected in a healthcare setting using the mLife True Oral Fluid/Viral Collection Kit.During the early phase of the coronavirus disease 2019 (COVID-19) pandemic, design, development, validation, verification and implementation of diagnostic tests were actively addressed by a large number of diagnostic test manufacturers. Under the reissued EUA, the RT-PCR-based test may now be used with pooled samples containing up to six individual samples, including self-collected nasal swab specimens collected in a healthcare setting and clinician-collected nasal, nasopharyngeal, and oropharyngeal swab specimens.Įxpress Gene received a reissued EUA for its 2019-nCoV RT-PCR Diagnostic Panel, which was first authorized in May for the detection of the SARS-CoV-2 ORF1ab, N, and S genes in respiratory tract specimens such as nasopharyngeal swabs and bronchoalveolar lavage. ![]() Roche received a reissued EUA for its Cobas SARS-CoV-2 test, which was originally authorized in March for the detection of SARS-CoV-2 nucleic acid in in nasopharyngeal and oropharyngeal swab samples from patients who meet the clinical and epidemiological criteria for testing. "That flexibility to match lab supply with patient demand in real-time is what enables RapidRona to consistently deliver test results within 48 business hours of taking the sample." "We offer CLIA-certified laboratories the opportunity to participate in the US testing effort as their capacity ebbs and flows," RapidRona Cofounder and CEO Heather Mlodinow said in a statement. ![]() Specimens are sent to authorized labs designated by the Chicago-based company for molecular testing, according to the FDA. The RapidRona Self-Collection Kit is designed for the at-home collection of nasal swab specimens. In June, the Covington, Kentucky-based company received FDA EUA for its COVID-19 Assay. The test may be performed only by Gravity. It runs on Thermo Fisher's Applied Biosystems QuantStudio 12k Flex and QuantStudio 7 instruments. The test uses Thermo Fisher Scientific's KingFisher Flex instrument and Hamilton's Microlab STAR system for nucleic acid isolation. It may also be used with nasal swab specimens self-collected using either the Everlywell COVID-19 Test Home Collection Kit or the Kroger Health COVID-19 Test Home Collection Kit, and with saliva specimens collected in a healthcare setting using the Spectrum Solutions LLC SDNA-1000 Saliva Collection Device. The Gravity Diagnostics SARS-CoV-2 RT-PCR assay is designed to detect the N, ORF1ab, and S genes of the virus in nasal, nasopharyngeal, and oropharyngeal swab specimens collected by healthcare providers from both symptomatic and asymptomatic individuals. ![]() The FDA also said it has reissued EUAs for SARS-CoV-2 tests developed by Roche and Express Gene to reflect their authorized use with additional sample types. NEW YORK - The US Food and Drug Administration on Monday granted separate Emergency Use Authorizations for a PCR-based SARS-CoV-2 test from Gravity Diagnostics and a sample self-collection kit from RapidRona. Advances in Clinical Genomics Profiling.
