[Popular science knowledge] Is the "cotton swab" of nucleic acid sample safe?certainly!

Worried that the nucleic acid sample swab is not safe?

Eliminate doubts,

Authoritative experts have answers.

Material Safety | Production Standard Safe | Safe in Operation

Material safety is similar to toothbrushes

In fact, the sample swab is not a cotton swab. Its material is polyester or nylon fiber, which is similar to the toothbrush in daily life.

Nucleic acid sampling is like brushing toothbrushes, but the sample is to take the cells in the throat wall in the mouth, and then put the sample swabs in the sampling pipe. Because the sample swab is used for polyester or nylon fiber, it is easy to get rid of the storage solution, which is convenient for the laboratory to perform related testing.

The production environment requires quality supervision and standards

The sampling swab is a medical device. The production environment and requirements are very strict. There are also relevant standards for quality supervision. The most basic standard is non -toxic and harmless. The sampling swab does not produce harmful substances during the production process.

Sample is not harmful to individuals

There will be some excitement during the sampling of nucleic acid, and different people feel different. For example, some people have a sensitive pharynx, feel uncomfortable after sampling, and have foreign body sensations, which will cause itching or vomiting, and some people will have a greater tolerance. Individual differences are relatively large.

There is also a situation that the mouth swabs usually need to open their mouths when sampling. Some people have soft palates together. If the sample person wants to ensure the sampling quality, you will explore it. As soon as you explore, there are stimuli. Some people have a strong stimulus reaction. There are vomiting and cough, but once the sample is completed, it is easy to relieve. So sampling does not hurt the individual.

Remind public friends to actively support and cooperate with sampling personnel when participating in nucleic acid testing. In accordance with their on -site requirements, standardize the sampling action to ensure the sampling effect.

According to the Oral Plazer Pipan Platform collection method released by the National Committee of the National Health and Health Commission, during the process of collecting the pharynx, the collector needs to give up slightly, and the mouth should be slightly open to expose the pharynx tonsils on both sides. The pharyngeal tonsils and the posterior wall of the pharynx are sampled. The human body's oral pharyngeal belongs to a soft tissue. During the collection process, it is necessary to keep some wiping and scraping, but also avoid damage to the post -pharyngeal wall. Try to avoid collecting wings and lips.
