Nucleic acid self-test kit refers to the Neococcal Pneumonia Antigen Self-Test Kit, which is used to detect Neococcal Pneumonia Virus antigens, not nucleic acids, and is used with a process of sample collection, antigen detection, and interpretation of the results, which need to be analyzed specifically. 1. Sample collection: when using the nucleic acid antigen self-test kit, you need to use the sampling swab into the nasal cavity at a depth of 1.5cm, in the left and right nostrils were rotated, at least 4 times to complete the sampling work. 2. Antigen Detection: After sampling is completed, the nasal swab needs to be put into the sample elution solution, soak for half a minute, while squeezing the swab head at least 5 times, and then drop the elution solution into the test card spiking hole, drop 3 to 4 drops can be, wait for 15 to 20 minutes. 3. Interpretation of results: The results should be interpreted as soon as possible after the antigen detection is completed, and incorrect results may be obtained if the time does not meet this criterion. When the C end of the card is red and the T end is red or yellow, the result is positive; when the C end is red and the T end is not colorful, the result is negative; when the C end is not colorful and the T end is red, it means that there is an error in the test and the result is invalid.
