简要总结
SARS-CoV-2 rapid antigen over the counter clinical performance evaluation
详细描述
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.

结局指标
主要结局
Positive Percent Agreement
时间窗: One hour
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.
Negative Percent Agreement
时间窗: One hour
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.
次要结局
