The Rapid COVID-19 Antigen Test is an in vitro immunochromatographic assay for the qualitative detection of nucleocapsid protein antigen from SARS-CoV-2 in direct nasopharyngeal (NP) swab from individuals who are suspected of COVID-19 by their healthcare provider. It is intended to aid in the rapid diagnosis of SARS-CoV-2 infections.
The novel coronaviruses belong to the β genus. COVID-19 is an acute respiratory infectious disease. Currently, individuals infected by SARS-CoV-2 are the main source of transmission; asymptomatic carriers are also known as a source of transmission. Based on the current epidemiological information, the incubation period can last from 1 to 14 days, where the average time before symptoms occur is about 5 days. The Healgen rapid COVID-19 Antigen test has been trialled and tested by Public Health England.
