Currently the nucleic acid kit may refer to the New Crown Antigen Detection Kit, the use of which includes pre-sampling preparation, sampling, sample testing, and reading the results.
Antigen test kit pre-sampling preparation includes washing hands with running water or hand sanitizer, opening the antigen test kit, taking out the instruction manual and reading it, opening the reagent bottle with buffer for spare use, and taking out the nasal swab sampler.
1. Blow your nose with tissue paper and carefully unpack the nasal swab, avoiding touching the swab head with your hands. Then tilt your head slightly, hold the end of the nasal swab sampler against one side of the nostril to enter, and then slowly go backward along the bottom of the lower nasal passage to a depth of 1~1.5cm and then rotate against the nasal cavity at least 4 times (stay for not less than 15 seconds), and then use the same sampler to repeat the same operation in the other side of the nostril after taking out the swab.
2. Immediately put the sampler into the sampling tube, the swab head should be rotated and mixed in the preservation solution for at least 30 seconds, and at the same time, the swab head should be squeezed with the hand across the outer wall of the sampling tube for at least 5 times, to ensure that the sample is fully eluted in the sampling tube.
3. Squeeze the liquid from the swab head through the outer wall of the sampling tube by hand, then discard the swab, cap the sampling tube, and drop the liquid vertically into the sample hole of the test card.
4. Wait for a certain period of time, read the results of the test card, C and T show red or purple bands are positive, a single band (C shows red or purple bands, T does not show bands) is negative, no band is invalid.
