Specification for nucleic acid sampling

Generally, the nucleic acid detection usually refers to COVID-19 nucleic acid detection. The requirements of nucleic acid sampling include fasting, fully exposing the pharynx, informing the relevant medical history in advance, wearing a mask and keeping a safe distance.

1, the nucleic acid sampler should be fasted for 2 hours before sampling.

2. When sampling, send an "ah" backwards to fully expose the pharynx and facilitate sampling.

3. Patients with a history of throat and blood should inform the medical staff in advance to avoid accidents during sampling.

Everyone should wear masks, don't talk, and keep a distance of more than one meter.

Sampling inspection of nucleic acid is an important link in epidemic prevention and control. Every citizen should do his duty, obey the arrangement of the government and complete nucleic acid sampling on time and in quantity.

1. The sampling cotton swab must touch the posterior pharyngeal wall and the left and right tonsils and scrape slightly. When sampling, hands must not touch the cotton swab head.

2. The red liquid in the nucleic acid detection solution is a protective solution, which is used to preserve the protein from being destroyed and contribute to the accuracy of nucleic acid detection results. Non-toxic and non-corrosive, it doesn't matter if it spills on your hands or skin. Sprinkle a little will not affect the test results, and if you spill too much, you need to change the tube.

3. Tighten the test tube after sampling to avoid leakage. Then put the sampling tube into the sampling bag, press it tightly and seal it. Pay attention to spray the front and back of the sampling bag with alcohol watering can and put it in the shade. No sun, no heat, no freezing.

4. Do not eat for two hours before nucleic acid sampling, and do not drink water, smoke, drink, chew gum or drink for half an hour.
