SARS-CoV-2 rapid antigen over the counter clinical performance evaluation
Coronavirus disease (COVID-19) is a disease caused by a newly discovered coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The SARS-CoV-2 is a β-coronavirus, which is enveloped non-segmented positive-sense RNA virus 2. It is spread by human-to-human transmission via droplets or direct contact, and infection has been estimated to have mean incubation period of 6.4 days and a basic reproduction number of 2.24-3.58. Among patients with pneumonia caused by SARS-CoV-2, fever was the most common symptom, followed by cough. On 11 March 2020, the COVID-19 outbreak was characterized as a pandemic by the WHO. Since then, over 70 million people worldwide have been infected with the virus with over 1.5 million deaths attributed to the virus. Laboratory testing for SARS-CoV-2 is currently being performed to determine if an individual has active infection via detection of viral RNA or if an individual has an immune response to the virus from a previous infection via detection of antibodies. Specimen collection is a crucial first step in the evaluation of an individual's SARS-CoV-2 infection status. The goal of this project is to evaluate a rapid SARS-CoV-2 antigen test for over the counter (OTC) use. Study subjects under EDP supervision, either in-person or via video conference, will collect and test anterior nasal swab samples and a Study Representative will collect and ship a second nasopharyngeal swab sample for comparator PCR testing. The Rapid SARS-CoV-2 Antigen Test collection and testing methodology is viewed as a convenient and inexpensive method to test clinical specimens for SARS-CoV-2 and OTC access will improve the availability of COVD-19 testing. The COVID-19 Antigen Rapid Test Device detects SARS-CoV-2 viral antigens through visual interpretation of color development. Anti-SARS-CoV-2 antibodies are immobilized on the test region of the nitrocellulose membrane. Anti-SARS-CoV-2 antibodies conjugated to colored particles are immobilized on the conjugated pad. A sample is added to the extraction buffer which is optimized to release the SARS-CoV-2 antigens from specimen. During testing, the extracted antigens bind to anti-SARS-CoV-2 antibodies conjugated to colored particles. As the specimen migrates along the strip by capillary action and interacts with reagents on the membrane, the complex will be captured by the anti-SARS-CoV-2 antibodies at the test region. Excess colored particles are captured at the internal control zone. The presence of a colored band in the test region indicates a positive result for the SARS-CoV-2 viral antigens, while its absence indicates a negative result. A colored band at the control region serves as a procedural control, indicating that the proper volume of specimen has been added and membrane wicking is working.

Candidate Ag self-test kit anterior nasal specimen collection and testing will be done under the supervision of qualified site personnel in person. Comparator NP samples shall be collected at least 15 minutes prior to Ag samples with at least 15 minutes between nasal collections including collections that may occur prior to study enrollment. Comparator samples will be collected first by qualified personnel at a study site or physician's office using an FDA authorized nasopharyngeal swab collection kit and SARS-CoV-2 molecular assay.

Positive Percent Agreement
The acceptance criteria for this study is Positive Percent Agreement (PPA) greater than or equal to eighty percent in a comparison between the Rapid SARS-CoV-2 Antigen Test and RT-PCR comparator test results. The PPA was defined as the proportion of true positive tests, defined by a concordant candidate and comparator test result of positive, out of all positive candidate test results.
Time frame: One hour
Negative Percent Agreement
The acceptance criteria for this study is Negative Percent Agreement (NPA) greater than or equal to ninety-eight percent in a comparison between the Rapid SARS-CoV-2 Antigen Test and RT-PCR comparator test results. The NPA was defined as the proportion of true negative tests, defined by a concordant candidate and comparator test result of negative, out of all negative candidate test results.
Time frame: One hour
Detection of Asymptomatic Positives
Number of participants with a positive PCR comparator result, but reported no symptoms or epidemiological reasons to suspect COVID-19 infection within the past 14 days. This will be compared to their Rapid SARS-CoV-2 Antigen Test result to determine the ability of the Rapid SARS-CoV-2 Antigen Test to detect individuals who are infected but are not symptomatic.
Time frame: One hour
