There are no chemical ingredients. The ingredients on the throat swab swab are only cotton and no other special materials.

The sample collector used for nucleic acid testing, namely the throat swab, has no special ingredients and is just an ordinary cotton product. Collect samples from the throat with cotton swabs and then store them in anti-protein lysis solution in test tubes, which can provide effective samples for nucleic acid detection experiments.

The fluorescent agents circulated on the Internet do not exist in cotton swabs. The fluorescence experiment is an experimental method for nucleic acid detection. It uses fluorescence to find the presence of the new coronavirus and does not need to be used during the sample collection process. Fluorescent agent, so the public can safely conduct nucleic acid testing, and generally there will be no adverse consequences caused by cotton swabs.

Nucleic acid testing swabs are safe

Nucleic acid testing swabs are disposable and generally safe.

Nucleic acid testing swabs are used to collect tissue from the human throat or nasopharynx for nucleic acid testing of the new coronavirus. In order to avoid contact transmission, the swabs are disposable and are given to each person. They will not There are usage issues, so it is generally safe.

In addition, medical staff will disinfect their hands when collecting samples from each person to minimize the possibility of infection.

During nucleic acid testing, you need to keep a distance of one meter from others, wear a mask and wash your hands frequently when you are not testing yourself.
