This rapid chromatographic immunoassay provides qualitative detection of SARS-CoV-2 antigens in swabs of the oral cavity, nasopharynx or nose. The SARS-CoV-2 test is essential to control the spread of COVID-19, an acute respiratory disease that can infect even asymptomatic individuals. Early detection by rapid tests such as this immunoassay helps to rapidly identify infected individuals so that they can be isolated and treated in time. This is particularly important to prevent outbreaks and to protect vulnerable populations, as COVID-19 can cause severe complications. Rapid tests also help healthcare providers to make informed decisions, reduce the burden on healthcare systems and reduce the spread of the virus in communities.
