In Vitro Diagnostic Antigen Assay Covid 19 Test Kit With Immunofluorescence Chromatography

15 Min Antigen Covid 19 Rapid Test Kit With Immunofluorescence

Method:

Rapid SARS-CoV-2 Antigen Test Card is an immunochromatography based one step in vitro test. It is designed for the rapid qualitative determination of SARS-CoV-2 virus antigen in anterior nasal swabs from individuals suspected of COVID-19 within the first seven days of symptom onset. Rapid SARS-CoV-2 Antigen Test Card shall not be used as sole basis to diagnose or exclude SARS-CoV-2 infection. Children under 14 years of age should be assisted by an adult.

Advantage:

Test Principle:

The reagent forms an antigen-antibody conjugate with SARS-Cov-2 antigen and is detected by a fluorescence detector to achieve a semi-quantitative determination of the concentration of SARS-Cov-2 antigen in human nasopharyngeal swabs or oropharyngeal swabs,
thereby achieving a qualitative interpretation of viral infection. After treatment, SARS-Cov-2 in the sample is added to the detection hole, antigen and latex labeled antibody (monoclonal antibody against SARS-Cov-2) form an immune complex.
The complex moves with the liquid to the nitrocellulose membrane, and the detection area of the nitrocellulose membrane is coated with another one.

Test Result:

When the monoclonal antibody is against SARS-Cov-2, the immune complex is captured by the antibody on nitrocellulose membrane, forming fluorescence signal:
the result is positive. When the sample does not contain SARS-Cov-2 antigen or is lower than the minimum detection limit of this kit, fluorescence signal appears in the detection area: the result is negative.
