Influenza A+B Rapid Test Kit

Test principle

This kit uses the double antibody-sandwich method to detect antigens.When an appropriate amount of specimen is added to the specimen well of the test device, the specimen will move forward along the test device. If the specimen contains influenza A antigen and/or influenza B antigen, the antigen binds to the antibody labeled with colloidal gold on the binding pad, and the immune complex forms a sandwich complex with another coated antibody which was coated on the test line, a visible colored line will show up, which indicates that the antigen is positive.

Test Procedure

Read the instructions carefully before use and bring test device, extraction reagent and specimens were restored to room temperature (15 ~ 30 ℃).

1.Specimen Collection

After Swab specimens were collected, swab can be stored in extraction reagent provided with the kit. Freshly collected specimens should be processed as soon as possible, but no later than one hour after specimen collection. Specimen collected may be stored at 2-8℃ for no more than 24 hours; Store at -70 ℃for a long time, but avoid repeated freeze-thaw cycles.

（1）If use Pharyngeal swab, gently wipe both sides of the patient’s pharyngeal tonsils back and forth at least three times.

（2）If use nasal swab, carefully insert the swab in the patient’s nostril. Swab over the surface of the posterior nasopharynx and rotate the swab several times.

2.Testing

（1）Tear off the sealing film on the antigen extraction tube.

（2）Put the swab specimen into the extraction tube, rotate the swab for about 10 seconds, and press the swab head against the tube wall to release the antigen in the swab.

（3）Remove the swab while squeezing the sides of the tube to extract the liquid from the swab.

（4）Hold the extraction tube vertically and add two drops of the test specimens into each specimen well (s). Start the timer.

3.Test Results
Interpret the results within 15 minutes. Strong positive results can be read within 15 minutes, however, negative results must be read after 15 minutes, and the results after 30 minutes are no longer valid.
