The Influenza A&B Rapid Test is a qualitative, lateral flow immunoassay for the detection of Influenza A and Influenza B nucleoproteins in nasal swab, throat swab or nasal aspirate specimens. In this test, antibody specific to the Influenza A and Influenza B nucleoproteins is separately coated on the test line regions of the test device. During testing, the extracted specimen reacts with the antibody to Influenza A and/or Influenza B that are coated onto particles. The mixture migrates up the membrane to react with the antibody to Influenza A and/or Influenza B on the membrane and generate one or two colored lines in the test regions. The presence of this colored line in either or both of the test regions indicates a positive result. To serve as a procedural control, a colored line will always appear in the control region if the test has performed properly. COVID-19 Antigen Rapid Test is an immunochromatographic membrane assay that uses highly sensitive monoclonal antibodies to New Coronavirus. The test device is composed of the following three parts, namely sample pad, reagent pad and reaction membrane. The whole strip is fixed inside a plastic device. The reagent membrane contains the colloidal-gold conjugated with the monoclonal antibodies against COVID-19; the reaction membrane contains the secondary antibodies for COVID-19, and the polyclonal antibodies against the mouse globulin, which are pre-immobilized on the membrane.When the sample is added into the sample well, conjugates dried in the reagent pad are dissolved and migrate along with the sample. If New Coronavirus is present in the sample, a complex formed between the anti-New Coronavirus conjugate and the virus will be caught by the specific anti-New Coronavirus monoclonal coated on the T region. Whether the sample contains the virus or not, the solution continues to migrate to encounter another reagent (an anti-mouse IgG antibody) that binds the remaining conjugates, thereby producing a red line on the region C.
