Do nucleic acid detection samples contain carcinogens?rumor!Don't believe in

Since the new crown epidemic,

Some inaccurate information and rumors appear from time to time,

This is not recently, nucleic acid detection sampling cotton swab

Rumors containing carcinogens such as fluorescent agents, ethylene oxide,

It has attracted the attention of the masses.

So, what exactly is the truth?

The illness and control little guards will be announced to everyone,

And make rumors about other rumors about samples,

Hurry up and see ~

According to the "Catalog of Medical Device", the "disposable sampling device" (commonly known as "sampling swab" used in the new crown virus nucleic acid and antigen detection can be divided into two categories: sterile and non -sterile, all of which are medical equipment. Its raw materials, production environment, and production processes must be strictly reviewed. The operation of the quality management system requires meet the requirements of the quality management of medical device production quality management. The product is expected to be tightly tested.

At present, the sampling shit material used on the market is mainly composed of nylon short fiber fluff head and medical -grade ABS plastic rod. It is a million tiny fibrous fiber vertically and uniformly covered on the end of the wiper handle. Compared with a toothbrush in daily life, compared with the toothbrush in daily life similar. "Because the nylon short fiber is closely fixed at the front end of the sampling swab in vertical, compared to the traditional cotton swabs can collect and elute samples more efficiently to improve the detection efficiency and accuracy."

This is a pseudo -concept. There is no such fiber material in the raw material market. The nylon short fiber raw material at the front of the sampling swab does not contain radioactive elements, carcinogenic fluorescent preparations and other substances, and the production process will not be introduced or produced.

"Fluorescent probe" is a type of fluorescent molecules that can be changed sensitively with the nature of the environment in ultraviolet-visible-near-infrared regions, and its fluorescent properties can be sensitively changed with the nature of the environment. A fluorescent probes will be used in some new coronal virus nucleic acid detection boxes using "fluorescent PCR method", but only in the sample nucleic acid detection link, the fluorescent probe will not be used at all. Therefore, the saying that the "sample swab professional name is fluorescent probe" mentioned in the rumor is purely Zhang Guanli Dai.

E -ethylene is an extremely common sterilization method in the field of medical devices. The sampling swab provided by the "sterile" form will conduct strict experimental verification on the measurement of epoxy oxide, sterilization time, temperature, pressure and other parameters when using ethylene oxide. E -ethylene ethylene analysis can be carried out for sale after passing the test. There is a period of analysis from factory to application, and when everyone may be connected to ethylene ethylene dregs when applying. Therefore, there is no epoxy ethane poisoning when using sampled samples. "

After each sampling, the situation where the pharynx and nose are uncomfortable are mainly due to individual differences and different operation methods of test personnel. These discomfort will soon be relieved after stopping sampling, and will not cause damage to the body.
