SalivaDirect: RNA extraction-free SARS-CoV-2 diagnostics Resource Report Resource Website |
Chantal Vogels, Doug E. Brackney, Chaney Kalinich, Isabel Ott, Nathan Grubaugh, Anne Wyllie | DOI:10.17504/protocols.io.bii4kcgw | Coronavirus Method Development Community | SalivaDirect is an RNA-extraction free, dual-plexed RT-qPCR method for SARS-CoV-2 detection. It can be broadly implemented as it (1) does not require saliva collection tubes containing preservatives, (2) does not require specialized equipment for RNA extraction, and (3) is validated for use with products from multiple vendors. Thus, the simplicity and flexibility of SalivaDirect means that it is not as affected by supply chain bottlenecks as some other assays. Our method is RNA-extraction free which enables testing of low volume and minimally processed saliva in dual-plexed RT-qPCR for SARS-CoV-2 detection. Saliva will be treated with proteinase K followed by a heat inactivation step, and is then directly used as input in the dual-plexed RT-qPCR test. Our aim was not to design new primers and probes for RT-qPCR testing, but rather to use validated primer and probe sets (N1 and RP) developed by the US CDC. The human Ribonuclease P (RP) probe was modified with a different fluorophore so that the primer/probe set could be combined in a dualplex assay, reducing the number of tests to 1 assay with 2 sets.Version 2 includes: Optimized thermocycler conditionsLocally validated alternative options for Proteinase K, RT-qPCR master mix, and thermocyclersUse of 8-strip tubes for sample processing step, due to contamination issues in 96-well plates.Version 3 has been updated to remove steps for sample self-collection. | Department of Epidemiology of Microbial Diseases, Yale School of Public Health, Department of Environmental Sciences The Connecticut Agricultural Experiment Station; Department of Epidemiology of Microbial Diseases, Yale School of Public Health, Department of Epidemiology of Microbial Diseases, Yale School of Public Health, Department of Epidemiology of Microbial Diseases, Yale School of Public Health, Department of Epidemiology of Microbial Diseases, Yale School of Public Health, Department of Epidemiology of Microbial Diseases, Yale School of Public Health | https://covidtrackerct.com/about-salivadirect/ | 3 | 2020 | Chantal Vogels, Doug E.

Nicola O'Reilly | DOI:10.17504/protocols.io.bfexjjfn | Coronavirus Method Development Community, Crick COVID-19 Consortium | Purpose of examination / Clinical relevanceAt the end of 2019, several pneumonia cases were reported in Wuhan, China and the pathogen was confirmed as a new viral strain. World Health organization has named the newly identified coronavirus as 2019-nCoV, also known as COVID19. The disease developed into a dangerous pandemic, posing major challenges to the NHS. Although more research is necessary to better understand the virus, in response to the emergency, simple and rapid testing is essential to identify the virus in infected individuals. This will aid the implementation of efficient interventions to contain the spread, and distinguish healthcare workers who have been infected, and are required to self-isolate, from those showing similar symptoms but which are not 2019-nCoV associated. The latter category may continue to work, alleviating stress on hard-pressed healthcare resources. 2019-nCoV is an RNA virus, and the diagnostic tests detect viral RNA in swabs from patient airways using a reverse transcriptase PCR assay.

vito | DOI:10.17504/protocols.io.bkvckw2w | Coronavirus Method Development Community | Qbiotix has developed novel nucleic acid assays and sample preparation procedures to improve global microbial detection standards and rapidly/inexpensively test high volume of samples. Qbiotix aims to enable countries to test their entire populations, their food, their waters with millions of tests per day on a regular basis.The assays are isothermal and homogeneous. Thermocycling is not required and amplification is non-enzymatic removing the need for complex instrumentation and reliance on variable quality enzymes. Critically we have removed the need for complex nucleic acid preparation, integrated the assay into the collection/transport solution and significantly reduced reliance on a complex supply chain. The assays remove a good proportion of the constraints of PCR which heretofore have inhibited the number of people being testing for SARS-CoV-2 in the US and globally. | Qbiotix | 1 | 2020 | vito 2020.

Saliva samples were self-collected by the patient. Upon waking, patients were asked to avoid food, water and brushing of teeth until the sample was collected. Patients were asked to repeatedly spit into a sterile 90 mL specimen collection cup until roughly a quarter full of liquid (excluding bubbles), before securely closing it. For patients unable to provide saliva (such as those on mechanical ventilation), clinical teams were advised that suction could be used to collect saliva into the cup (or a sputum trap container for improved containment and safety). Collected volumes ranged from 0.5 - 20 mL. All saliva samples were stored at room temperature and transported to the research lab at the Yale School of Public Health within 5 hours of collection, with RNA for SARS-CoV-2 detection extracted within 12 hours of collection. When possible, saliva samples were stored at +4°C, otherwise they were kept at room temperature.Asymptomatic healthcare workers. Asymptomatic healthcare workers were asked to collect ~10 mL of saliva into a sterile specimen collection cup. No specific instructions were given regarding food intake etc prior to collection. Samples were delivered to the research lab at the Yale School of Public Health within 6 hours of collection and stored for up to 6 hours at +4°C until aliquoting for RNA extraction.
