It has been noted that
Nucleic acid testing is no stranger to citizens. But do you also have these questions about the small sampling "cotton swab" in nucleic acid detection: Is it made of cotton? What are the sanitary conditions? Is it harmful to your health? ..... 10 June10, the professionals of Chongqing drug administration gave detailed answers to the questions you were concerned about.
Q: Are cotton swabs used for nucleic acid detection and sampling?
A: Not a cotton swab, but a sampling cotton swab.
Q: What is a sampling swab? What's the difference between it and a cotton swab?
A: Sampling swab is a tool to collect samples such as viruses and bacteria. It generally consists of a swab head and a swab stick.
The difference between the two is mainly reflected in the composition and use:
1. The tip of the cotton swab is made of medical absorbent cotton, and the cotton swab stick is generally made of natural birch or bamboo stick, which is often used for cleaning wounds and applying medicine.
2. The swab head of sampling swab is generally made of chemical synthetic fibers such as polyester (also known as "polyester") and polyamide (also known as "nylon") through flocking process. Swab sticks are generally medical-grade ABS plastics with breakpoints, which are often used for sampling virus or bacteria samples.
Q: How is the sampling swab produced? Is it safe?
A: Most cotton swabs are produced in a clean environment required by current laws and regulations and do not need sterilization. These products are filed and managed in accordance with Class I medical devices. A few special cotton swabs are sterilized after being produced and packaged in a clean environment, and such products are registered and managed according to Class II medical devices. Sterile medical devices can only be put on the market after passing the inspection.
Q: Is the follow-up detection process of nasal swab and throat swab the same?
A: The commonly used COVID-19 swab mainly includes throat swab and nose swab. Clinically, the sampling site is different, and so is the follow-up test. At present, most samples are taken from pharynx and a few from nose. In addition, there are a few mixed examinations of pharynx and nose.
Q: Is sampling swab harmful to health?
A: Sampling cotton swabs are as harmless to human body as cotton swabs. In addition, a very small number of swabs provided in an aseptic way, if sterilized with ethylene oxide, will not pose a safety risk to the human body after analysis and inspection.
Q: Why does my throat sometimes feel uncomfortable after nucleic acid testing?
Answer: This is because the fiber on the cotton swab head has fallen off. However, the normal sampling time is short and the movement is relatively light, which generally does not lead to a large number of fibers falling off. Occasionally, fiber shedding is normal. It is recommended to rinse your mouth with clean water after sampling.
