Detailed steps on how to use the antigen test card:

　　1. Before the self-test, you need to wash your hands.

　　2. After washing your hands, open the kit and read the instructions carefully.

　　3. Check the sampling tube and test card.

　　4. When collecting samples, first blow your nose with toilet paper, carefully unpack the nasal swab, and avoid touching the swab head with your hands.

　　5. Slightly lift the head, hold the end of the swab in one hand and paste it into one nostril, and slowly penetrate backwards along the bottom of the lower nasal passage for 1-1.5 cm (for subjects aged 2 to 14 years, 1 cm deep) and then stick it in The nasal cavity is rotated at least 4 times, and the dwell time is not less than fifteen seconds, and then the same swab is used to repeat the same operation on the other nasal cavity.

　　6. Immediately immerse the swab head into the sampling container containing the preservation solution that comes with the test strip. The swab head should be rotated and mixed in the preservation solution for at least 30 seconds, and at the same time squeeze the swab head through the outer wall of the sampling tube by hand At least five times, squeeze the liquid from the swab head through the outer wall of the sampling tube with your hands, and then discard the swab.

　　7. After the sampling tube is capped, drop 3-4 drops of the liquid vertically into the sample hole of the test card. If you encounter a viscous sample and the chromatography cannot start after adding the sample, you can increase the amount of the drop to 6 drops. , false negative or invalid results may occur if too little solution is added to the test card.

　　8. According to the instructions of the reagents, the results should be read within 15-20 minutes. Less than or overtime readings may lead to wrong results. A positive result shows red or purple bands at both C and T, and a red or purple band at T. The color of the band can be dark or light. A negative result shows a red or purple band at C and no band at T. If there is no red or purple band at C, it does not matter whether there is a band at T , such results are invalid and require resampling for detection.

　　9. There are two ways to deal with the used self-test reagents. The first one is for isolated observers. Whether the test result is positive or negative, all used sampling swabs are put into sealed bags, and the management personnel refer to medical waste or According to the procedures, if the test results of community residents are negative, the test items should be put into sealed bags and treated as general garbage. Institutional disposal as clinical waste.
