Introduction

The WESAIL Flu+COVID-19 antigen self test kit remains capable of detecting the mutated omicron coronavirus variant (download manufacturer’s certificate). The Flu+COVID-19 Ag Test Kit is used for the qualitative detection of the influenza A virus, influenza B virus and SARS-CoV-2 antigen in human nasopharyngeal or nasal swab specimens and is designed to assist the differential diagnosis of influenza A, influenza B and COVID-19. For professional use.

Principle of the procedure

This kit is based on the principle of lateral flow colloidal gold immunoassay and detects the influenza A virus, influenza B virus and SARS-CoV-2 antigen in specimen via immuno-sandwich methodology.

When the sample is added to the sample well, the influenza B virus protein in the sample reacts with the gold labeled antibody and forms an immuno-complex, which will flow onto the nitrocellulose membrane. When the immuno-complex reaches the test band B, it will react with the influenza B antibody pre-coated on the nitrocellulose membrane and will be fixed on the test band B and develop color, which indicates a positive result.

When the sample is added to the sample well, the influenza A virus protein in the sample reacts with the gold labeled antibody and forms an immuno-complex, which will flow onto the nitrocellulose membrane. When the immuno-complex reaches the test band A, it will react with the influenza A antibody pre-coated on the nitrocellulose membrane and will be fixed on the test band A and develop color, which indicates a positive result.

When the sample is added to the sample well, the SARS-CoV-2 antigen in the sample reacts with the gold labeled antibody and forms an immuno-complex, which will flow onto the nitrocellulose membrane. When the immuno-complex reaches the test band COVID, it will react with the COVID-19 antibody pre-coated on the nitrocellulose membrane and will be fixed on the COVID test band and develop color, which indicates a positive result.

Regardless of whether the sample contains influenza A virus, influenza B virus or SARS-CoV-2 antigen, the gold labeled quality control antigen will bind to the coated antibody at the C band and develop color.

Test Procedure

Please read the product insert of the kit carefully.

1. Collect nasal or nasopharyngeal swab from the patient in accordance with standard operating procedure.

2. Pierce the sealing membrane of lysis buffer tube with the tip of nozzle cap.

3. HUnplug the nozzle cap from the tube and place it on the workbench with the protective cover facing down. Be careful not to touch the nozzle tip to avoid contamination.

4. Insert the swab into the lysis buffer tube. Squeeze the tube and stir the swab for 5 times.

5. Keep squeezing the tube and remove the swab. Make sure all the liquid from the swab is removed.

6. Install the nozzle cap with the protective cover facing up. Mix the tube by gently shaking for 10 times. Let stand for 1 minute.

7. Remove the protective cover. Squeeze the tube and discard the first two drops of processed specimen.

8. Add three drops of processed specimen vertically into the sample well, and then let stand for 15 minutes.

9. Read the test result immediately, the test result will be invalid after 30 minutes.

Result Interpretation

Result Interpretation

Positive 1: colored bands appear at both test band (B) and control band (C). This display shows a valid positive result for influenza B.

Positive 2: colored bands appear at both test band (A) and control band (C). This display shows a valid positive result for influenza A.

Positive 3: colored bands appear at both test band (COVID) and control band (C). This display shows a valid positive result for COVID-19 Ag.

Positive 4: colored bands appear at test band (B), test band (A) and control band (C). This display shows a valid positive result for influenza B and influenza A.

Positive 5: colored bands appear at test band (B), test band (COVID) and control band (C). This display shows a valid positive result influenza B and COVID-19 Ag.

Positive 6: colored bands appear at test band (A), test band (COVID) and control band (C). This display shows a valid positive result for influenza A and COVID-19 Ag.

Positive 7: colored bands appear at test band (B), test band (A), test band (COVID) and control band (C). This display shows a valid positive result for influenza B, influenza A and COVID-19 Ag.

Negative: colored band appears at control band (C) only.

Invalid 1-8: no visible colored band appears at control band. The test procedures may not be followed correctly, or the cassette is deteriorated. It is recommended to retest the specimen.

Note: The color intensity of the test band (COVID), (B) or (A) may vary according to the concentration of antigen in the sample. The lower the concentration, the weaker the intensity. The determination of a positive result should be based on the presence of the test band (COVID), (B) or (A) and control band (C), regardless of whether the test band (COVID), (B) or (A) is weaker than the control band (C).
