BIOER COVID-19 Antigen Test Kit (colloidal gold method) — Estimated US$3.5 / one test

The COVID-19 Antigen Test Kit (colloidal gold method) is a lateral flow immunoassay for qualitative detection of antigen from SARS-CoV-2 in human nasopharyngeal swabs & oropharyngeal swabs from individuals who are suspected of COVID-19. The operation steps are simple and test results are interpreted visually at 15-20 minutes based on the presence or absence of visually colored lines. The diagnosis can be achieved within 1-7 days after infection, which is of great significance for prognosis and targeted treatment.

Product details

COVID-19 Antigen Test Kit (colloidal gold method) is a rapid, qualitative immunochromatographic assay for the determination of the presence of SARS-CoV-2 antigens in human nasopharyngeal or oropharyngeal swab specimens.When specimens are processed and added to the test card, SARS-CoV-2 antigens present in the specimen bind to antibodies conjugated to detector particles in thetest strip. Then the antigen-antibody complexes migrate toward the membrane by capillary action to the reaction area. The complexes then are captured by anti-SARS-CoV-2 monoclonal antibodies immobilized at the test line region and acolored line appears on the membrane. Test results are interpreted visually at 15-30 minutes based on the presence or absence of visually colored lines. To serveas an internal control, a visible control line will always appear in the control lineregion after proper volume of specimen has been added to indicate a test result is valid.
