What kind of virus sampling tube do you know? Does the following look like what you know? The following is introduced to you by Disposable Virus Sampling Tube Manufacturers — Cell medical (Dongguan) Co., Ltd.

What is Virus Sampling Tube? When should the virus preservation solution be used?

Virus transport medium, virus preservation solution: a protective liquid medium added to the virus sampling tube to protect the samples after nasopharyngeal swab sampling.

Generally, in the process of nucleic acid detection, we cannot directly conduct nucleic acid PCR experiments at the sample collection site.

If we need to check the samples collected by the flocked swab, we need to add the virus preservation solution.

Why use a virus sampling tube?

First of all, we have to understand what is a virus? Why does it need a virus sampling tube?

What is a virus?

Virus: a non-cellular form composed of nucleic acid molecules and proteins.

It lives on parasitic hosts and is an organic species between living and non-living bodies.

It is one end of DNA or RNA wrapped in a protective shell.

Through the mechanism of infection, these simple organisms can use the host’s cellular system to replicate themselves but are unable to grow and replicate independently.

Viruses can infect almost all living organisms with cellular structures.

Virus detection is different from conventional biochemical detection.

The virus itself is a simple microorganism and must be parasitic in living cells.

After sampling, when the virus leaves the host cell, its protein shell and nucleic acid degrade rapidly in the sampling tube.

So that the nucleic acid During the test, it is impossible to determine whether the initially collected sample contains the virus, which is likely to cause false negatives.

A virus delivery medium (virus sampling tube), a general-purpose sampling product: for sampling various virus samples, chlamydia samples, and ureaplasma samples.

Short-term storage and transportation at 2-8°C, and -80°C refrigerator or liquid nitrogen Long-term preservation in the environment.

1. For monitoring and sampling infectious pathogenic microorganisms by disease control departments and clinical departments.

Suitable for influenza virus (common influenza, highly pathogenic avian influenza, influenza A H1N1 virus, etc.), hand, foot and mouth virus and other types of virus sampling. It is also used for sampling Mycoplasma, Chlamydia, Ureaplasma, etc.

2. To transport nasopharyngeal swab specimens or tissue specimens from specific parts from the sampling site to the testing laboratory for extraction and testing.

3. Preserve nasopharyngeal swab samples or tissue samples from specific parts for necessary cell culture.

4. For short-term storage and transportation of virus samples at 2-8°C and long-term storage in a -80°C refrigerators or liquid nitrogen environments.

There are two types of virus preservation solutions: inactivated and non-inactivated

The inactivated virus preservation solution is mainly a virus lysis type preservation solution improved by nucleic acid extraction lysis solution, which is added with a high concentration of lysis salt, which can quickly and efficiently deactivate the virus protein in the sample to be tested and can effectively prevent infection.

At the same time, it also contains an RNase enzyme inhibitor, which can protect virus nucleic acid from degradation.

As long as the subsequent NT-PCR experiment can detect the nucleic acid of the virus, we can diagnose it.

Stored at room temperature for a relatively long time.

The non-inactivated preservation solution is mainly a virus maintenance solution that is improved on the basis of the transport medium.

It can retain the protein coat of the virus and the viral nucleic acid DNA or RNA at the same time so that the virus has the integrity of the protein epitope and nucleic acid in vitro.

Of course, there is also a certain risk of infectivity when the operation is wrong.

It is necessary to keep a strictly low temperature for long-term storage after sampling.

No matter what kind of virus preservation solution it is, we must test it as soon as possible after sampling or keep it strictly at a low temperature to ensure that the detection is accurate.

Due to the rapid reproduction and mutation of the virus, the virus preservation solution plays a crucial role in maintaining the stability of the virus sample.

Manufacturers CellMedical Virus Sampling Tube Kits Advantages

1. Add protein-stabilizing components such as BSA to the sampling solution to reduce the speed of virus decomposition and greatly improve the positive rate of virus isolation.
2. It is stable at room temperature and can keep its activity within 1 year.
3. Gentamicin replaces penicillin to avoid allergic reactions;

4. Using flocked swabs, the sample has a higher collection rate and release rate;
Samples can be stored for a long time (-20 ℃ ordinary refrigerator, -80 ℃ low-temperature refrigerator, -197 ℃ liquid nitrogen);
6. Thickening and anti-leakage design to ensure that the sample does not leak, in line with WHO regulations and biosafety regulations.

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

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

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?

Sterile flocked swabs specimen collection

Sterile flocked swabs specimen collection

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!

I believe everyone knows the impact of the new crown epidemic on us.

I believe you all know the impact of the new crown epidemic on us.

As the number of COVID-19 cases across the country starts to climb again.

Everyone has started to discuss it again, and I believe that no topic can attract the attention of the world for such a long time like our current global new crown virus.

Some of us have raised such a question, why do we have two detection methods for nucleic acid detection points.

One is for extraction in the nose, and the other is for extraction in the mouth?

Nasopharyngeal swabs and oropharyngeal swabs only take different paths.

The oropharyngeal swab is to collect oropharyngeal specimens by entering the sampling swab through the mouth.

The nasopharyngeal swab is to collect nasopharyngeal specimens through the nose.

Nasopharyngeal swab sampling： A thin flocked swab into the nostril, from the lower nasal meatus to the posterior wall of the nasopharynx.

And then twisting the swab for sampling.

The depth of the sampling swab into the nasal cavity is approximately the distance from the tip of the nose to the earlobe.

How to collect a Nasopharyngeal (NP) swab

1. Keep your head still, to remove the secretion on the surface of the anterior nostril;

2. Measure the distance from the tip of the nose to the earlobe with a swab as well as mark it with your finger. Put the swab right into the nasal dental caries in the direction perpendicular to the nose (face), and also reach the posterior nasopharynx when it comes across resistance, to make sure that the swab stays in the nose for 10-15 s, gently rotate 3 to 5 times to secure the examination piece.

There is definitely no demand for the sampler to stand straight opposite the patient. The advantage of standing on the side is that if the patient has coughing, sneeze, etc, it can be avoided in time.

It is vertical to the coronal airplane of the head or the face and also permeates deeply from the inferior meatus to the posterior wall of the nasopharynx, as well as it is enough to feel the wall surface. The depth of the nasopharyngeal swab right into the nasal tooth cavity is about the range from the pointer of the nose to the earlobe (see picture).

Nasopharyngeal sampling

Nasopharyngeal sampling

3. The nasopharyngeal swab must be turned on the nasopharyngeal mucosa, maintained for 10-15 secs, and after that got rid of. The kid’s participation is poor. In practice, we typically obtain the swab in three to five secs after completely twisting it 2-3 times.

Nasopharyngeal swab vs nasal swab

A nasal swab (often called an anterior nose test): A sample taken by touching both sides of the nasal wall. The nasopharyngeal swab is to probe from the nose to the throat.

What is the nasal swab technique?

The nasal swab approach uses a swab to accumulate an analysis example from the nasal membrane. The nasal swab examination (frequently described as the former nasal test) involves putting the swab around 0.5-0.75 inches deep into the nostril as well as turning it in one nostril for 10-15 seconds while touching both sides of the nasal wall, then making use of the same cotton swab, Gather in the other nostril similarly. Since this approach is less invasive, it is usually extra comfortable for the patient – and is additionally the approach utilized when self-testing.

nose structure

Nose structure

Nasopharyngeal swab

Impacted by elements such as age and also face structure development, there are private differences in the collection deepness of nasopharyngeal swabs.

We should pay attention to personal protection when collecting nasopharyngeal swabs, and clean the nasal cavity before collection.

If the patient has nasal septum curvature, the background of nasal surgery, rare coagulation characteristics, etc., the patient should inform the collection staff in advance to avoid damage to nasal caries.

During collection, the patient should tilt his head back to ensure smooth entry of the nasopharyngeal swab.

It might be accompanied by discomfort and discomfort in the nasal tooth cavity.

Furthermore, nasal bleeding might happen after nasopharyngeal swab collection.

A percentage of blood loss does not call for unique therapy. If the amount of blood loss is huge or lasts for a long time, you must go to the hospital for hemostasis therapy in time.

Additionally, clients with signs and symptoms such as edema as well as blood loss in the nasopharynx should stay clear of nasopharyngeal swab collection to avoid worsening the problem. Before the nasopharyngeal swab collection, you must avoid taking antibacterial and also antiviral drugs to stay clear of impacting the examination results.

Cell medical nasal swab adopts jet nylon fiber implantation technology, which is first-class in the domestic and foreign markets. Such material can absorb more samples.

What is flocking swab?

Flocked swab refers to the process of applying multiple fibers on the surface of adhesive coating; If the cotton swab is a Flocking material, it is a flocking swab.

It is a one-time sampling cotton swab composed of nylon short fiber velveteen wool head and ABS plastic rod.

It is suitable for oronasopharynx samples, cervix, vagina samples, laboratory tests, etc.

So, what is the difference between flocked cotton and traditional cotton?

Because it does not have the Du cushion core structure of the traditional sampling bed, the sample setting out is difficult, which affects the integrity of sampling.

Compared with cotton swab, the whole sample is adsorbed near the surface of the sampling head and can be released quickly and completely.

The nylon fiber in the vertical direction can improve the cell collection effect as a soft brush. Under the strong hydraulic pressure, the liquid sample is adsorbed on the surface close to the sampling head by nylon fiber bundle, so it is easy to release.

Why is a flocking Swab better than a traditional cotton swab?

Compared with traditional samples, flocking swabs have the following differences.
1. The Cell medical  flocking sample sampling swab does not have mutually absorbed nuclei and cannot disperse and collect samples.
2. The flocking cotton swab can be collected quickly, so that the whole sample can adhere to the villus surface and elute fully.
3. The vertical nylon fiber is like a soft bristle brush, which can improve the effect of collecting cell samples.
4. The capillary action between fiber bundles promotes the strong hydraulic absorption of liquid samples and makes the samples close to its surface easy to elute.
5. Flocking cotton swab is an ideal method to collect a large number of cells. It can not only elute quickly, but also release these cells into the delivery medium quickly.

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.

About flocked swab specimens

Nasopharyngeal sampling swabs are composed of nylon short fiber pile head and medical grade ABS plastic rod.

The nylon short fiber acts like a soft brush, which can effectively improve the collection of cellular material;

the capillary movement between the fibers forms a strong hydraulic pressure, thus ingesting the liquid sample;

at the same time, the sample clings to the surface of the swab and is easy to wash off.

Cell medical (Dongguan) Co., Ltd. Sterile flocked swabs collect and elute samples more effectively than any other disposable swabs on the market.

The high-quality fiber and swab physical manufacturing process produce sterile flocking swabs, which is an ideal choice for rapid diagnostic testing.

The rapid release of whole cells and the ability to better collect cells make these swabs the perfect specimen collection for any laboratory or research center.

The ideal collection device must be able to absorb and release samples and maintain their activity.

This is why flocking cotton swabs innovate sample collection equipment.

Sterile flocked swabs collect and retain sample vitality, provide better sample yield, and allow rapid release of samples into liquid media.

Attention

1.The insertion direction of the swab is perpendicular to the face of the subject, not along the nostril.

2.When there is resistance when the swab enters, it shall retreat slightly. Under the condition that the subject tolerates it, readjust the angle before continuing to insert, and do not insert violently.
