The product adopts cross-flow immunoassay, it used for the qualitative detection ofnovel Coronavirus antigen in suspected patients nasopharyngeal and oropharyngeal swabs.
Wide range of applications: suitable for hospitals, disease control centers, communities,airports, stations, customs, schools, enterprises, etc.
【Sample Requirements】
A polyester sponge sample with a PP (polypropylene) rod is recommended for sterile sample collection.
(1) The collection method of oropharyngeal sample: the head of the collected person is slightly tilted, the mouth is open, and the pharyngeal tonsils on both sides are exposed.Apply the swab across the base of the tongue to the pharyngeal tonsils on both sides of the recipient for at least 3 times, and then wipe the swab up and down the posterior pharyngeal wall for at least 3 times.
(2) Nasopharyngeal sample collection method: sampling personnel gently support the head of the collected personnel with one hand, with one hand holding the swab, the swab is inserted into the nostril, and slowly penetrate backward along the bottom of the inferior nasal meatus. Because the nasal meatus is curved, excessive force should not be used to avoid traumatic bleeding.When the top of the swab reaches the posterior wall of the nasopharynx, gently rotate the swab once (pause for a moment in case of reflex cough), and then slowly remove the swab.
(3) Sample treatment: Samples collected should be treated with the sample buffer provided by this kit as soon as possible (if not immediately processed, the samples should be stored immediately in a dry, sterilized and tightly sealed plastic tube), and stored at 2℃ to 8℃ for no more than 24h;Long-term storage at -70℃, but repeated freezing and thawing should be avoided.
Test Method
Restore all reagents to room temperature before testing. The test should be conducted at room temperature.
I. Extraction of specimens (see Figure 1)
1. Add 400μL (about 10 drops) sample buffer vertically to the sample extraction tube, then insert the sampled sample into the solution, rotate close to the inner wall about 10 times, so that the sample can be dissolved in the solution as much as possible.
2. Squash the sample tip along the inner wall of the extraction tube to keep the liquid in the tube as much as possible, remove and discard the sample.
3. Cover the emitter.
II. Test Procedure (See Figure 2)
1. Remove the test card from the sealed bag.
2. Add 2 drops (about 80μl) of the treated sample extract to the adding well of the test card, and then start the timer.
3. Read the results when the test card is placed at room temperature for 15 minutes.The result was invalid after 20 minutes.
Interpretation of test results
① Invalid results: no reaction line appeared in the quality control line (line C), and the test was invalid. The experiment should be redone.
② Negative results: a red ribbon, quality control line (line C) color.
③ Positive result: two red bands, color display on both test line (T line) and quality control line (C line).
