This product uses lateral flow immunoassay for novel coronavirus resistance in nasopharyngeal swabs and nasopharyngeal swabs in suspected infected patients Primary testing
Extensive application: applicable to hospitals, CDC, communities, airports, stations, customs, schools, enterprises, etc.
【Sample Requirements】
PP(polypropylene rod is recommended.
(1) Acquisition method of oral pharyngeal test: the head is slightly tilted, mouth wide, exposing the pharyngeal tonsils on both sides. Wipe the swab over the root of the tongue, wipe the pharyngeal tonsils back and forth on both sides of the recipient at least 3 times, and then wipe down the posterior pharyngeal wall at least 3 times.
(2) Collection method of nasopharyngeal test: the sampling person gently supports the collected person's head and the swab, sticks the nostrils, and slowly penetrates back along the bottom of the lower nasal canal. Due to the nasal canal in an arc, do not exert too hard to avoid traumatic bleeding. When the top of the swab reaches the back wall of the nasopharyngeal cavity, gently rotate for a week (stay for a moment in case of a reflex cough), and then slowly remove the swab.
(3) Sample Treatment: collected samples shall be treated with sample buffer as soon as possible provided in this kit (if not processed immediately, samples shall be stored in dried, disinfected and strictly sealed plastic pipes), stored under 2 ℃ ~8 ℃ not exceeding 24h,;-70 ℃ for a long time, but repeated freezing and thawing shall be avoided.
Test Method
[Test Method] Please restore all reagents to room temperature before testing, and the testing shall be conducted at room temperature.
Extraction of specimens (see Figure 1)
1. adds 400 μL(about 10 drops) sample buffer vertically to the sample extraction tube, then inserts the sample test into the sample extraction tube, rotating closely against the inner wall about 10 times to make the specimen dissolve in the solution as much as possible.
2. shall squeeze the cotton swab head of the test tube along the inner wall of the extraction tube to keep the liquid in the tube as much as possible, and remove and discard the test son.
3. Cover with the drops.

Test procedure (see Figure II)
The 1. removes the detection card from the sealing bag.
2. processes the sample extract with 2 drops (about 80 μL) to the sample hole of the test card, and then activates the timer.
Read the results when the 3. test card is placed at room temperature for 15 minutes. Invalid read result after 20 minutes

Interpretation of test results

Judgment figure of the test card result shows:
Invalid ① result: the quality control line (C line) has no reaction line, invalid detection, and should be retested.
② negative result: a red ribbon, quality control line (C line) color display.
③ positive results: two red bands, test lines (T) and mass control lines (C).
