This product uses cross-current immunoassay to be used for qualitative testing of the novel coronavirus antigen in nasopharyngeal and oral pharyngeal swabs of suspected patients.
Wide range of applications: suitable for hospitals, disease control centers, communities, airports, train stations, customs, schools, businesses, etc..
【Sample Requirements】
We recommend aseptic sampling using a polyester sponge with a PP (polypropylene) stick.
(1) How to grate the oropharyngeal specimen: The subject tilts his head slightly and opens his mouth to expose the amygdala of the pharynx on both sides. Wipe both sides of the pharyngeal amygdala at least 3 times through the root of the tongue. Then wipe above and below the posterior wall of the pharynx at least three times.
(2) How to grate the nasopharyngeal sample: The grabber lightly supports the grabbed person's head with one hand, holds the wipe with one hand, inserts it into the nostril, and slowly back along the bottom of the inferior nasal passage. Infiltrate. The nasal meatus is bent, so use excessive force to avoid traumatic bleeding. When the tip reaches the posterior wall of the nasopharynx, gently turn it once (stop for a while if you have a reflex cough) and slowly remove it.
(3) Sample processing: The swallowed sample must be treated with the sample buffer provided by this kit as soon as possible (if not treated immediately, it must be dried, sterilized and stored in a sealed plastic tube immediately. Do not), and store at 2 ° C-8 ° C for no more than 24 hours; store at -70 ° C for extended periods of time, but avoid repeated freeze-thaw.
Test Method
Bring all reagents to room temperature before testing. The test should be conducted at room temperature.
I. Sample extraction (see Figure 1)
1. Put 400 μL (about 10 drops) of buffer solution vertically in the sample extraction tube, insert it into the solution, bring it close to the inner wall and rotate it about 10 times to dissolve as much as possible.
2. Squeeze the tip of the sample along the inner wall of the extraction tube, leave as much liquid as possible in the tube, and take out the sample.
3. Cover the transmitter.
II. Test Procedure (See Figure 2)
1. Remove the test card from the sticker bag.
2. Add 2 drops (about 80 μl) of the treated sample extract to the addition hole of the test card and activate the timer.
3. Place the test card at room temperature for 15 minutes before reading the results. After 20 minutes, the result was invalid.
Interpretation of test results
(1) Invalid result: The test was invalid because the reaction line did not appear on the quality control line (C line). This experiment should be redone.
② Negative result: Red ribbon, color of quality control line (C line).
③ Positive result: Two red bands, test line (T line) and quality control line (C line) are both displayed in color.
