Worry about the unsafe nucleic acid sampling swab?
4 eliminates doubts, and
authoritative experts have answers.
Material safety | Production standard safety | Operation safety
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 has requirements. Quality supervision has standards.
sampling swabs are medical devices. 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. 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 where the mouth is usually opened when sampling oropharyngeal swabs. Some people have their soft palate and the root of the tongue is put together. If the sampling person wants to ensure the quality of the sampling, he will look inward and look for the posterior pharyngeal wall and tonsils. There will be stimulation when it is explored. Some people have a very strong stimulation reaction, and vomiting and coughing occur, but once the sampling is completed, it will be easy to relieve it. Therefore, sampling does not harm the individual.
reminds the public to actively support and cooperate with the sampling personnel when participating in nucleic acid testing, 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 collection of pharyngeal swabs, the person being collected needs to slightly tilt his head and slightly open his mouth to expose the pharyngeal tonsils on both sides. The sampler needs to sample on the pharyngeal tonsils and the posterior pharyngeal walls 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.
