Covid-19: Antigen Test Self-Test Swabs Must Be Sterilized?

Posted on by

Covid-19 antigen test self-test swabs must be sterilized?

New crown antigen test self-test sampling swabs must be sterilized? Alcohol disinfection is required before “non-sterile sterilization”?

Yesterday, a colleague looked at the record, it was about the swab used for the self-testing agent for the covid-19 antigen.

One user found that the swabs were non-sterile flocked swab during use, while some communities received sterilized cotton swabs.

Therefore, it is recommended to sterilize the flocked swab with 75% alcohol before using it.

Experts and industry insiders say such concerns are unnecessary as long as qualified products from formal channels are used.

If citizens receive swabs that are suspected to be damaged or contaminated, please discard them directly according to relevant requirements.

Is it risky to use “non-sterile” and “unsterilized” sampling swabs?

Specifically, there are two main problems that netizens worry about:

First, they are worried that the sampling swabs will be “bacteria”, which will affect the results of antigen testing.

Such as “false positives” And so on;

The second is to worry about the “bacteria” of the sampling flocked swab.

During the sampling process, the “bacteria” will be brought into the human body, affecting health.

75% alcohol can indeed disinfect cotton swabs, but a flocked swab with 75% alcohol may denature the scraped viral proteins!
The antigen is no longer that antigen, so it may lead to missed detection!

You must know that the antigen test “looks” for the antibodies produced by the new coronavirus infected person.

The display window of the reagent strip contains a protein that can recognize the antibody, like a dam, which intercepts the colloidal gold combined with the virus antibody, which is displayed in the display window. is red.

Therefore, even if the sampling swab contains “bacteria”, the kit will “ignore” it and focus on “finding” the antibodies produced by the new coronavirus infected person.

Since the kit is not interfered with by “bacteria”, it will not affect the results of antigen detection.

For some people who think that “bacteria” sampling swabs will affect human health, experts say that this may be due to a lack of understanding of “sterile” products.

Sterile ones are the best.

However, the use of sterile flocked swabs is not mandatory, and the use of non-sterile ones will not affect the detection effect.
For the EU CE self-test, it must be equipped with a sterile CE certified swab.
Non-sterile flocked swabs also have requirements for the number of colonies.
Non-sterile swabs are also sold in the EU (probably for professional use).
A group of friends also said: “I would rather not sterilize it. As it is now, if the epoxy desorption time is not enough, it will be sold. It is better not to sterilize it. Anyway, the oral and nasopharynx is not a sterile environment, so what are you afraid of?”
The expert replied: “Swabs are generally sterilized by irradiation, and less sterilized by ethylene oxide (EO). Even if sterilized by EO, they are packaged in dialysis paper. The general standard for ethylene oxide analysis is 14 days. If the heat is accelerated, it will usually be out in 3 days. Counting the storage and logistics time.
It is basically enough for 14 days, and it is safe for the testers.”

In summary:

The European self-test product is equipped with a sterilized swab, which seems to be a product below the European standard.
At the same time, non-sterile swabs can also be used, but they must meet quality inspection standards, such as colony count.
Finally, remind everyone, do not to use alcohol to disinfect swabs, which may cause missed inspections! Of course, the outer package of the reagent can be sterilized if it is conditional!

Flocked refers to the process of applying multiple lengths of fibers to the surface of the adhesive coating.

It is basically the same as the cotton swab except for the material.

It can also be said that the flocking adheres to the head of the flocked swab. It is a flocking swab, but it is different from cotton swabs in that it is a disposable sampling swab composed of nylon short fiber fluff head + ABS plastic rod.

advantages of flocking as a sampling swab

When it comes to sexual sampling swabs, I believe you don’t feel strange at this time.

Because most of the detection tools used for nucleic acid detection are disposable sampling swabs.

Sampling swabs directly contact our human organs, such as nasal swabs and pharyngeal swabs for nucleic acid detection.

So the material selection of sampling head is very important, and the material of sampling head is closely related to subsequent detection. The sampling swab shall ensure the sampling amount and release amount, and the selected material shall not have substances that affect the subsequent detection.

·Compared with the traditional winding swab, the amount of samples collected and released by flocked swab is three times higher, and it will not cause harm to human body.

·The sampling time of flocking swab is 3-5 seconds, which is fast and convenient to improve work efficiency.

Only by extracting samples faster can we complete the collection and analysis more efficiently.

·Moreover, through the directional friction effect of the brush fiber layer,effective collection of samples.

Therefore, the flocking swab is particularly conducive to the collection of trace DNA.

·A large number of clinical experiments show that compared with ordinary sterile cotton swabs, flocking swabs have a better effect on the collection and transportation of clinical microbial samples. This is especially true for those specimens that cannot be submitted for examination in time and placed for too long.

What’s the use of a flocked nose swab？

Nasal swab detection is a kind of nucleic acid detection, which is used to detect the presence of viral nucleic acid in the body. So as to determine whether the human body infected with COVID-19.

Nasal swab detection requires collecting cells deep in the throat of the tested person and placing them in a Petri dish for observation. Because New Coronavirus is mainly transmitted through the respiratory tract,if the human body is infected with COVID-19, there will be a lot of viruses in the throat. Therefore, it is a more accurate way to detect the existence of COVID-19 by detecting the cells in the throat.

What is the method of mini nasal swab collection?

① Please keep the patient’s head still and remove the secretions on the surface of the anterior nostril;

② use a flocked swab or other tools to the distance from the nostril to the root of the ear and mark it with your fingers;

③ insert the swab gently and slowly through the nasal cavity;

④ swab until the finger mark or stay for several seconds after encountering resistance to absorb secretions; (generally stay for 15-30 seconds, and then rotate gently for 3 times);

⑤ gently rotate the swab and put it into the virus sampling tube (transport medium); Break the swab tail rod along the breaking point and place it completely in the tube. Tighten the pipe cover.

⑥ If you need to collect from two nostrils, you should use another swab.

⑦ Send to the inspection room for inspection as soon as possible.

⑧ Note the information of the collected person to avoid confusion.
