There is no phosphor on the swabs used to do nucleic acids. Pharyngeal swabs are collected from the pharynx and tonsils of the examinee. Pharyngeal swabs for nucleic acid testing refer to the use of pharyngeal test swabs to obtain sputum specimens and take the specimens for nucleic acid testing of the New Crown Pneumonia Virus (NCPV) during the current New Crown Epidemic. Fluorescent powder (commonly known as thousand-variable luminous powder ), is usually divided into two categories: photo-reservoir luminous powder and luminous powder with radioactivity .
Precautions:
The claim that sampling swabs are poisonous is 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.
