[Scientific Power] Is the cotton swab detected in the nucleic acid test really hygienic?

Since the new crown epidemic, rumors about viruses and epidemic prevention have never subsided. The "cotton swabs" used in nucleic acids are the hardest hit areas of rumors and rumors. In the past two days, there were another hot article, which mentioned cotton swabs in it. Today, we will discuss this, I hope to help everyone reduce some anxiety.

Some netizens even wrote the above questions about the "Remembering Avenge of Nuclear Testing".

Yesterday evening, my mother and I went to do nucleic acid testing.

(Let me mention it first, I have done nucleic acids in college, and cotton swabs are dismantled in front of us. The specific operation is to open my mouth-cotton swab to explore it and lightly scrape it twice-OK)

When it was my turn, I didn't see the cotton swabs just taken out, or for a long time. The nurse took a cotton swab to rotate at least 5 laps in my throat, and I vomited.

After I was my mother, she was also rotated for six or seven circles by the nurses with a cotton swab in her throat. She made her very painful. She said that the cotton swab had a sour taste. After returning, her throat was uncomfortable. I woke up this morning to look at the mirror, and a small bag (at the throat) had a small bag, and the extra small bag made her uncomfortable.

So, is the cotton swab testing of nucleic acid detection? Should the detection personnel be the kind of ordinary volunteer who has never studied medical treatment? Malizing the acidity of acid is normal, but it is not so ruthless. A layer of film in my throat was swear as if I didn't stop.

In fact, the above netizens are purely concerned.

In the NetEase column "Made in China", it is mentioned that the quality of our country requires the quality of cotton cotton for medical cotton swabs must meet the requirements of YY0330-2002, hold the "Medical Device Registration Certificate", and pass the factory inspection conclusion. The cotton fiber of the cotton swab should be soft , White, odorless, must not have macular, stains, and foreign bodies. The cotton sticky rolls should be loose inner tight and outer, and the 100G tension cotton head should be completely shed. The rod should be able to withstand 100G external forces without permanent deformation or broken.

Medical cotton swabs and ordinary cotton swabs are also very different in the production process.

During the production process of ordinary cotton swabs, the main operation is to stick cotton to paper sticks and shape; while the production process of medical cotton swabs is much more complicated, it must be produced in a clean area, and a sterilization program has been experienced in a clean area, and a sterilization program has been experienced. Essence The sterilization section is usually used for ethylene oxide, and its sterilization is adapted to the width of the surface, and the cost is low. However, due to ethylene oxide residues, the national standards are specifically stipulated that after 14 days of medical cotton swab, the residual amount of ethylene oxide per gram of cotton should not exceed 10 micrograms.

In fact, the real name of "cotton swab" used by our nucleic acid is "Disposable Sample", which is usually called "sample swab". Essence

In the newly revised "First Class of Medical Device Products List" of the State Drug Administration, the clear sample swab is recorded for a class of equipment. The relevant person in charge of the National Health and Health Commission also publicly pointed out that the production environment requirements and quality supervision standards of sampling swabs are very strict.

A small medical cotton swab contains the crystallization of many scholars' research. Whether it is the improvement of the production process or the improvement of the use method, medical workers continue to guard you and my health with their rigor and meticulousness.

Therefore, cotton swab can cause cancer, which is a rumor.

After the new crown epidemic is popular, there is also a "information epidemic" accompanied by the epidemic. False information will always spread at an unexpected speed.

Not only the virus that needs to be blocked now, but also rumors.

The scientific power will be as usual as always, which will spread interesting and useful scientific knowledge. Welcome to continue to pay attention!
