VivaDiagᵀᴹ SARS-CoV-2/Flu A/Flu B Ag Rapid Test is based on immunochromatography technology.
Each test device has one line of anti-SARS-CoV-2 antibody on the detection line (CoV line), one line of anti-influenza A antibody on the detection line (A line), one line of anti-influenza B antibody on the detection line (B line) and one line of anti-mouse IgG antibody on the quality control line (C line). When extracted specimen is added to each specimen well, it will react with the labeled antibody to form a complex; the mixture then migrates through the membrane by capillary action and interacts with the coated anti-SARS-CoV-2 antibody, anti-influenza A antibody and anti-influenza B antibody on the detection line.
If the specimen contains SARS-CoV-2, influenza A or influenza B antigen, the detection line will appear red indicating the SARS-CoV-2, influenza A or influenza B antigen is positive. Otherwise, the test result will be negative. The test device also contains a quality control line C which should appear red for all valid tests. If the quality control line C does not appear, the test result will be invalid even if the detection line appears.
