Is there a fluorescent agent on the cotton swab for nucleic acid?

There is no phosphorus for nucleic acid on the cotton swab. Swallow swabs were collected from the throat and tonsils of the subjects. Pharyngeal swab nucleic acid detection means that during the epidemic period in COVID-19, sputum samples were obtained by throat swab method, and the samples were tested for COVID-19 virus nucleic acid. Fluorescent powder (commonly known as changeable luminous powder) is usually divided into two categories: photosensitive energy storage luminous powder and radioactive luminous powder.

Precautions:

The statement that "sampling cotton swabs are toxic" on the Internet is completely nonsense. Sampling cotton swabs are produced for sampling, and they do not contain any soaking reagents, nor do they need to contain reagents; At the same time, sampling swab belongs to medical devices, and the basic requirement of qualified products is non-toxic and harmless.

According to national regulations, disposable samplers belong to a class of medical device products. Not only production filing, but also strict production environment requirements and quality supervision standards. Qualified products must be non-toxic and harmless.

At the same time, "disposable sampler" is a universal product in the medical field, which can sample different parts for different detection behaviors. It is not specially produced for nucleic acid detection or antigen detection, so the cotton swab will not contain other reagents.
