The sample collector used for nucleic acid detection, that is, throat swab cotton swab, has no special components and is an ordinary cotton product. Samples were collected from throat with cotton swabs and then stored in anti-protein lysate in test tubes, which can provide effective samples for nucleic acid detection experiments.
However, the fluorescent agent circulating on the internet does not exist in cotton swabs, and fluorescence experiment is an experimental method for nucleic acid detection. We can find out whether there is COVID-19 by fluorescence, and we don't need to use fluorescent agent in the process of sample collection, so people can rest assured that nucleic acid detection will not cause any adverse consequences due to cotton swabs.
The cotton swab used for nucleic acid detection is safe.
Cotton swabs used for nucleic acid detection are disposable and usually safe.
The cotton swab used for nucleic acid detection is used to collect tissues of human throat or nasopharynx, and then detect COVID-19 nucleic acid. In order to avoid contact and spread, cotton swabs are disposable and there is no problem of * * *, so they are generally safe.
In addition, when collecting samples from everyone, medical staff will disinfect their hands to minimize the possibility of infection.
When testing nucleic acid, you need to keep a distance of one meter from others. When you don't test yourself, you should wear a mask and wash your hands frequently.
