What is a nucleic acid sampling mark?

The nucleic acid sampling mark shows the sampling time, sampling city and specific sampling point of all people in this area. When the nucleic acid detection result of this sampling information is updated, the nucleic acid sampling flag will be hidden. The red liquid in the nucleic acid detection sampling tube is the inactivated nucleic acid sample preservation solution. The throat swab samples collected by nucleic acid detection should be temporarily stored in a sampling tube filled with red liquid. The basic solution is an improved virus nucleic acid extraction lysate, and other components include colored dyes, guanylate, etc. Its biggest function is to store the test samples at room temperature.

Sampling, also known as sampling, refers to the process of converting continuous quantities in time domain or space domain into discrete quantities. It also refers to the process of converting analog audio into digital audio. In the field of digital image processing, it is defined as the digital operation of image space coordinates. The number of samples sampled per second is called the sampling frequency.

Can I eat mints before nucleic acid testing?

The whole nucleic acid detection process is relatively simple. Before nucleic acid testing, it is generally recommended not to eat food to prevent inaccurate sampling. Mint is a kind of candy food, which is usually not recommended.

The reason why it is not recommended to do nucleic acid test after eating is mainly because it may cause throat discomfort when sampling, especially when using throat test paper to extract throat secretions, which may induce the symptoms of nausea and vomiting of the sampled person. Therefore, it is recommended not to eat before doing nucleic acid test, but it still has no great influence like mints.

Matters needing attention in nucleic acid detection

1. Try to avoid eating and vomiting 2 hours before nucleic acid detection.

2. Smoking, drinking and chewing gum shall not be allowed within 30 minutes before sampling.

3. Testers need to wear masks correctly, take off masks before testing, and put on masks immediately after testing. You can prepare a spare mask to replace it in time after pollution.

4. When collecting oropharyngeal swabs, the tester leans back and opens his mouth to make an "ah" sound, which helps to expose the throat, but there will be symptoms such as irritating dry cough, nausea and vomiting in the process. The tester can cooperate with the collector to relax and breathe deeply as much as possible.

5. Pay attention to hand hygiene before and after nucleic acid detection, and wipe your hands with hand-free disinfectant or alcohol.
