NCoV Antigen Detection(Immunochromatography) Test Method

 

Intended Use


This product adopts transverse flow immunoassay for novel coronavirus antibody in nasopharyngeal swab and oropharyngeal swab of patients with suspected infection Scheduled test
Widely used: suitable for hospitals, disease control centers, communities, airports, stations, customs, schools, enterprises, etc.
 

Sample Requirements


 

[sample requirements]
It is recommended to use PP (polypropylene) rod polyester sponge test for aseptic test for collecting samples.
(1) Collection method of oropharyngeal test specimen: The head of the person to be collected is slightly inclined, and his mouth is opened to expose the pharyngeal tonsils on both sides. Pass the swab over the tongue root, and wipe it back and forth on the pharyngeal tonsils on both sides of the collected person with a little force for at least 3 times, and then wipe it up and down on the posterior pharyngeal wall for at least 3 times.
(2) Collection method of nasopharyngeal specimen: The sampler gently supports the head of the collector with one hand, and holds the swab with the other hand. The swab enters the nostril, and slowly penetrates backward along the bottom of the lower nasal passage. Because the nasal passage is curved, do not use too much force to avoid traumatic bleeding. When the top end of the swab reaches the back wall of the nasopharynx cavity, gently rotate for one week (in case of reflex cough, stop for a minute), and then slowly take out the swab.
(3) Sample treatment: the collected samples should be treated with the sample buffer provided by this kit as soon as possible (if it can't be treated immediately, the samples should be immediately stored in a dry, sterilized and strictly sealed plastic pipe), and stored at 2℃ ~ 8℃ for no more than 24 hours. Long-term preservation at -70℃, but repeated freezing and thawing should be avoided.

Test Method


[Inspection Method] Please restore all reagents to room temperature before testing, and the testing should be carried out at room temperature.

Sample extraction (see figure 1)
1. add 400μL (about 10 drops) of sample buffer vertically into the sample extraction tube, then insert the sampled sample into the solution in the sample extraction tube, and rotate it close to the inner wall for about 10 times, so that the sample can be dissolved in the solution as much as possible.
2. Squeeze the cotton swab head of the test specimen along the inner wall of the extraction tube to keep the liquid in the tube as much as possible, and take out and discard the test specimen.
3. Cover the emitter.

Test procedure (see figure 2)
1. take out the test card from the sealed bag.
2. Drop 2 drops (about 80μL) of the processed sample extract into the sample adding hole of the test card, and then start the timer.
3. Read the result when the test card is left at room temperature for 15 minutes. After 20 minutes, the reading result has no effect

 

Interpretation of test results


Figure for judging test card results:
① Invalid result: there is no reaction line in the quality control line (C line), the test is invalid, and the experiment should be repeated.
② Negative result: a red color band, and the quality control line (C line) shows color.
③ Positive results: Two red bands, both detection line (T line) and quality control line (C line) showed color.
