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
【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).
