# Yaozero Zero Plan# While everyone was fighting the epidemic together and actively cooperating with the closure, control and testing, a rumor spread in the circle of friends to the effect that “the cotton swabs used for sampling have reagents on them, which are poisonous”, and some netizens even said that the elderly at home saw the relevant rumors Later, I did not want to participate in nucleic acid screening, and also asked the younger generation to try not to undergo nucleic acid testing and antigen testing.
What is the cotton swab used for nucleic acid detection and antigen detection? Are there any reagents on it? Is it really poisonous?
The cotton swabs for nucleic acid detection and antigen detection are mainly in the form of nasal swabs and throat swabs. The throat swabs are generally 15 cm long, and the nasal swabs are 6 cm to 8 cm long. Antigen detection kits The relevant person in charge of the production enterprise introduced that the “cotton swabs” used for sampling are not the same as the absorbent cotton swabs we use daily. They should not be called “cotton swabs”, but “sampling swabs”, which are mainly made of nylon short fiber fluff. Head and medical grade ABS plastic rod constructed.
Sampling swabs use a flocking method of spray and electrostatic charge, allowing millions of nylon microfibers to attach vertically and evenly to the shank end.
The flocking process does not produce toxic substances. The flocking method makes the nylon fiber bundles act like capillaries, which is conducive to the absorption of liquid samples like strong hydraulic pressure.
So why do some people experience mild sore throat, nausea and other symptoms after taking the test? The relevant person in charge of the antigen detection kit manufacturer said that this has nothing to do with the sampling swab. It may be due to individual differences, some people’s throats are more sensitive, or it may be caused by the operation of the testing personnel. It will be relieved soon after the collection is stopped, and it will not cause harm to the body.
In addition, sampling swabs belong to single-use samplers, which are a class of medical device products. According to national regulations, not only production must be filed, but also strict production environment requirements and quality supervision standards are required. Qualified products are definitely toxic free and safe.
Therefore, in terms of materials, production, processing, and inspection processes, sampling swabs have strict standards to ensure that they are non-toxic and harmless, and can be used with confidence.
