Oropharyngeal Nasopharyngeal Swab Rapid Antigen Test For Hospitals CDC
NCoV Antigen Detection(Immunochromatography) Sample Requirements
Intended Use
Sample Requirements
(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.
