Product Details

       Rapid SARS-CoV-2 antigen test card is a one-step in vitro test based on immunochromatography. It aims to quickly and qualitatively determine the SARS-CoV-2 virus antigen in anterior nasal (front nose), oropharyngeal or nasopharyngeal swabs of individuals suspected of SARS-CoV-2 through its healthcare provider within the first 7 days of onset of symptoms. Rapid SARS-CoV-2 antigen test card cannot be used as the basis for diagnosing or excluding SARS-CoV-2 infection. Rapid SARS-CoV-2 Antigen Test Card detects the SARS-CoV-2 nucleocapsid protein (N protein). Theoretically, genetic SARS-CoV-2 variants with non-nucleocapsid protein mutations do not affect the product performance.

       The novel coronaviruses belong to the β genus. COVID-19 is an acute respiratory infectious disease. People are generally susceptible. Currently, the patients infected by the novel coronavirus are the main source of infection, asymptomatic infected people can also be an infectious source. based on the current epidemiological investigation, the incubation period is 1 to 14 days, mostly 3 to 7 days. The main manifestations include fever, fatigue and dry cough. Nasal congestion, runny nose, sore throat, myalgia and diarrhea are found in a few cases.

       Rapid SARS-CoV-2 antigen test card is an immunochromatographic lateral flow device using the principle of double antibody sandwich method. Anti-SARS-CoV-2 antibody was used as detection reagent. Goat anti mouse antibody was used in the control line system.The colloidal gold-conjugated anti-SARS-CoV-2 antibody was dry-fixed on the test equipment. After adding the specimen, it will diffuse through the test strip through the capillary and migrate to re-water alloy conjugated complex. If it exists or exceeds the detection limit, the SARS-CoV-2 virus antigen will react with the gold conjugate complex to form particles, and the particles will continue to migrate along the test strip until the test area (T) captured by the immobilized antibodies. Anti-SARS-CoV-2 antibody forms a visible red line. If there is no SARS-CoV-2 virus antigen in the sample, there will be no red line in the test area (T). The gold conjugate complex will continue to migrate alone until it is captured by the antibody immobilized in the control zone (C) to form a red line, which indicates the validity of the test.
