Product Description
COV19/ FluA/ FluB Antigen Combo Rapid Test Kit (Colloidal Gold Method)
Packing Specifications
The kit is an in vitro immunochromatographic assay for the qualitative detection of Cov19, Influenza A and Influenza B virus antigens in human nasopharyngeal, oropharyngeal swab, and salvia samples.
Cov19 is an acute respiratory infectious disease that humans are easily infected with. According to current epidemiological investigations, the incubation period is 1 to 14 days, mostly 3 to 7 days. The main symptoms are: fever, fatigue, dry cough, in a few cases can appear nasal congestion, sore throat, myalgia and diarrhea. Influenza, often called the flu is caused by the influenza virus. It is a highly contagious viral infection of the respiratory tract that can be spread by coughing or sneezing. Influenza outbreaks occur every fall and winter. There are influenza A, B and C viruses. Influenza A viruses are more prevalent than influenza B and Cand causes more severe illness.
Cov19 infection and Influenza virus infection have similar symptoms, such as fever, cough, etc. This kit can simultaneously detect the antigens of the three viruses and provides an easy workflow, short turnaround time, and rapid diagnosis of Cov19, Influenza A and influenza B virus infections using nasopharyngeal, oropharyngeal swab or salvia samples.
The kit is an immunochromatographic assay,based on double antibody sandwich method to detect Cov19 and Influenza A/B virus antigens. This method does not require expensive medical instruments and consumables. After adding the extracted specimen to the sample well on the test cassette, Cov19, Influenza A/B virus antigens in the sample will interact with the colloidal gold-labeled anti-CoV-2 and Influenza A/B antibodies on the conjugate pads. Then the conjugate pad will release re-solubilized conjugate onto the nitrocellulose membrane. The nitrocellulose membrane (NC membrane) diffuses it forward.
As the sample moves along the device binding reagents situated on the nitrocellulose membrane bind to the target at the test line. If the sample contains a COV19 antigen, it will bind to the colloidal goldanti-CoV-2 Np monoclonal antibody, diffuse forward, and then react with the anti-CoV-2 Np monoclonal antibody immobilized on the NC membrane detection line (COV19 Test line). Similarly, if the specimen contains Influenza A/Influenza B antigens, the antigens will react with antibody-coated particles, the conjugate migrate laterally forward, and cause a colored lines (A, B linesrespectively).
