COVID-19 rapid test

for antigensTBSARS-COV-2

Easy to use and easy to get the specimen, no equipment required, no PCR lab required. Convenient. Can be used in many places like station, airport, hospital, school and very convenient. Combo Rapid Test Test Principle COVID-19 Antigen/Influenza A+B Antigen Combo Rapid Test is based on colloidal gold immunochromatography assay. During the test, specimens and detection buffer are applied to the test cartridges. If there are SARS-CoV-2 nucleocapsid antigens or influenza A/B virus in the specimens, they will bind to colloidal gold-labeled antibodies against SARS-CoV-2 N protein or Influenza A and B virus antigens respectively on conjugation pad forming virus antigen-antibody-colloidal gold complexes (complex A for Flu A, complex B for Flu B and complex C for COVID-19 ). During latral flow, the complexes move along nitrocellulose membrane toward one end of the absorbent paper. When passing the COVID-19 test line TC (coated with another monoclonal antibody against SARS-CoV-2 N protein), the complex C is captured by capture antibody resulting in coloring on line TC; when passing the Influenza A test line TA (coated with another monoclonal antibody against Influenza A virus N protein), the complex A is captured by capture antibody resulting in coloring on line TA; when passing the Influenza B test line TB (coated with another monoclonal antibody against Influenza B virus N protein), the complex B is captured by capture antibody resulting in coloring on line TB; when passing the line C, residual colloidal gold-labeled control molecule is captured by quality-control antibody resulting in coloring on line C.
