COVID-19, Flu A&B, and RSV Antigen Test

Introducing the QualiVirus™  Test Kit

We have developed the QualiVirus™ COVID-19, Flu, and RSV Antigen test for over-the-counter (OTC) use to easily test the three types of viruses in one single test. The test uses a double antibody sandwich method to detect SARS-CoV-2, RSV, Influenza A, & Influenza B by colloidal gold lateral flow immunoassay. With the COVID-19 and RSV test in one chamber on the left side of the cassette and the FLU A&B viruses on the right-side chamber of the cassette. After nasal swab sampling, the samples soaked in the extraction buffer can be dropped into the sample wells. When samples containing an antigen of a particular virus flow to the designated N, R, A or B area, the antigen will form immune complexes with corresponding antibody labeled with colloidal gold, generating a clear red color line.
