This kit is only used for the in vitro qualitative detection of Multiple Respiratory Multipathogen Antigen SARS-CoV-2/Respiratory Syncytial virus/Influenza Avirus/Influenza B virus from human nasopharyngeal swabs specimens.SARS-CoV-2/RSV&Flu A/B Antigen Rapid Test Kit is an immunochromatographic double-antibody sandwich assay intended for the qualitative detection and differentiation of SARS-CoV-2/ Respiratory Syncytial virus/Influenza Avirus/Influenza B virus from individuals who are suspected of respiratory tract disease infection. This kit is suitable for the auxiliary diagnosis of respiratory diseases the results are for clinical reference only and cannot be used as the sole basis for diagnosis and exclusion decision. The clinical diagnosis and treatment of patients should be considered in combination with their symptoms/signs medical historyother laboratory tests and treatment responses, Positive test result needs to be further confirmed negative result does not preclude respiratory diseases viruses infection.

The kit is immunochromatographic and uses double-antibody sandwich method to detect SARS-CoV-2/ Respiratory Syncytial virus/Influenza A virus/Influenza B virus. During detection, the treated specimens are loaded into the sample wells of the test card.When the concentration of SARS-CoV-2/Respiratory Syncytial virus/Influenza A virus/Influenza B virus in specimen is higher than the minimum detection limit. the viral antigen will form complexes with labeled antibodies first. Under chromatography, the complexes move forward along the nitrocellulose membrane till captured by pre-coated monoclonal antibody of SARS-CoV-2/ Respiratory Syncytial virus/Influenza A virus/Influenza B virus in detection zone on nitrocellulose film(T1/T2/A/B) to form a red reaction line on the detection zone at this point the result is positive. Conversely, if there is no viral antigen or the concentration of antigen in specimen is below the minimum detection limit, no red reaction line appears in the detection zone, at this point the result is negative.Regardless of whether the sample contains viral antigens or not, a red reaction line will appear in the quality control zone(C),the red reaction line that appears in the quality control zone(C) is the criterion for determining if the chromatography process is normal.
