Worry about the unsafe nucleic acid sampling swab?
eliminates doubts, and
authoritative experts have answers.

Material safety Similar to toothbrush
In fact, the sampling swab is not a cotton swab, its material is polyester or nylon fiber, which is similar to toothbrushes in daily life.
Nucleic acid sampling is like brushing teeth with a toothbrush, but the sampling is to brush the posterior pharyngeal wall in the mouth to take cells, and then put the sampling swab in the sampling tube. Because the sampling swab uses polyester or nylon fiber, it is easy to get out of the storage liquid, which makes it easier for the laboratory to conduct relevant testing in the future.
Production environment requirements. Quality supervision has standards.
Sampling swabs are medical devices. The production environment and requirements are very strict. Quality supervision also has relevant standards. The most basic standard is non-toxic and harmless. No harmful substances are produced during the production process of sampling swabs.
sampling does not harm individuals
There will be some stimulation during the nucleic acid sampling process, and different people feel it differently. For example, some people have a sensitive throat and feel uncomfortable after sampling and feel foreign body sensation, which will cause itch or vomiting. Some people will tolerate itchy. There are quite a lot of individual differences.
There is another situation. When sampling oropharyngeal swab, you usually need to open your mouth. Some people soft palate put the root of the tongue together. If the sampler wants to ensure the sampling quality, he will look in and look for the back wall of the pharyngeal. , tonsils are stimulating when they are explored. Some people have very strong stimulation reactions in and , and vomiting and coughing occur, but once the sampling is completed, it is easy to relieve it. Therefore, sampling does not harm the individual.
reminds the public that when participating in nucleic acid testing, we must actively support and cooperate with the sampling personnel, and standardize the sampling coordination actions in accordance with their on-site requirements to ensure the sampling effect.
According to the oropharyngeal swab collection method issued by the National Health Commission, during the process of collecting pharyngeal swab , the collected person needs to slightly tilt his head and slightly open his mouth to expose the pharyngeal tonsils on both sides. The patient needs to sample the pharyngeal tonsils and the posterior pharyngeal wall on both sides. The human oropharynx is a soft tissue. During the collection process, it is necessary to maintain some force to wipe and scrape, and at the same time avoid damage to the posterior pharyngeal wall. Try to avoid collecting swabs to touch the cheeks and lips. Source: Healthy China
