There is no phosphor on the swabs used for nucleic acid. Pharyngeal swabs are collected from the pharynx and tonsils of the examinee. Pharyngeal swabs for nucleic acid testing refer to the pharyngeal swab method of obtaining sputum specimens during this new crown outbreak, and taking the specimens for nucleic acid testing for the new crown pneumonia virus. Fluorescent powder (commonly known as thousand-variable luminous powder), usually divided into two categories: photostorage luminous powder and luminous powder with radioactivity.
Precautions:
The claim on the Internet that "sampling swabs are toxic" is complete nonsense. Sampling swabs are produced for sampling, and do not contain any soaking reagents, nor do they need to contain reagents; at the same time, sampling swabs belong to the medical device, the basic requirements of qualified products is non-toxic and harmless.
According to national regulations, the single-use sampler belongs to a class of medical device products, not only the production should be filed, but also to have a strict production environment requirements and quality supervision standards, qualified products are certainly non-toxic and harmless.
At the same time, the "single-use sampler" belongs to the medical field of general products, can be sampled on different parts, but also applied in different testing behavior, not especially for nucleic acid detection or antigen detection production, so the swab will not contain other reagents.
