Brief Summary

The current standard of care for diagnostic of SARS-CoV-2 infection involves sample collection which is then prepared and measured via real time-polymerase chain reaction (RT-PCR). This process is time consuming and dependent on expensive instrumentation and trained technicians to perform both the sample preparation and assay. In many cases, sample turn-around times can take hours to several days. There are no established monitoring nationwide protocols for COVID-19 prevention of infection. Due to the lack of such protocols, this study will provide the proper experience to design a safe monitoring schema of asymptomatic cases of COVID-19. Self-testing using currently available RDT has a high specificity and relatively high sensitivity to identify individuals with a high probability of contagiousness. Therefore, we intend to use these RDT (Rapid diagnostic tests) for other use. There are several studies that point to the importance of the use of RDTs to monitor COVID-19 (3). The recent metadata indicate that the performance of the antigen test is crucial for obtaining good results to detect positive cases. We have already validated in the laboratory and using relevant clinical samples several different labels of antigen tests and we have compared them with already approved USA FDA antigen tests to confirm their performance prior to using them in this study. This project aims to monitor once a week the presence of SARS CoV-2 antigens using anterior nares (AN) swab self-process, executing the test and recording of the result, immediately after. The lack of affordable diagnostic tests which can detect the presence of SARS-CoV-2 in the general population which can give near real-time results is one critical missing control intervention in USA for the control of the pandemic and the spread of this disease. As public health restrictions begin to ease and people return to normal activities, while the COVID-19 pandemic is still a threat, a rapid diagnostic assay that does not require the sophisticated laboratory equipment and techniques could provide a significant advantage to screen asymptomatic individuals. The routine use of such rapid tests is a key element to show efficacy of protocol. We adjusted to once a week testing based on the medium to low risk of the elderly population of this study. The list of rapid nucleoprotein tests utilized in the current study are: NETO Corona test, Novir INSTA-TM COVID-19 Rapid Antigen test, COVICHEK COVID-19 Ag Test, SpectraBiotech COVID-19 track antigen test, Blandford Biotech AS-15™ Rapid Antigen Detection Kit SARS-CoV-2 Test (Colloidal Gold Method), Abbott BinaxNow tests. BACKGROUND The SARS-CoV-2 Direct Antigen Rapid Test ("Lateral flow") is an immunoassay developed for the qualitative detection of SARS-CoV-2 viral particles/secreted protein in anterior nasal swabs and/or saliva samples from both asymptomatic and suspected participants with COVID-19 infection. Lateral flow strips are printed with a monoclonal antibody that binds the signature SARS-CoV-2 viral particles/protein (Test line) and a control antibody (Control line) for quality control. A second monoclonal antibody is attached to gold nanoparticles (conjugate) and quencher buffer, and mixed with the nasal sample. The SARS-CoV-2 nucleocapsid protein attach to both antibodies resulting in a visual line on the test strip within 15 minutes. Prior experience in the detection of virus and viral proteins via antibody binding using lateral flow have been done through IDx20, Inc. The Housing Authority and the Public Health Department of the City of Chelsea will be overseeing this study.
