What are UTM Swab, Swab Kits?

On November 9, 2021, South Africa detected a B.1.1.529 variant of the new coronavirus from a case sample for the first time. In just 2 weeks, the mutant strain became the absolute dominant mutant strain of the new crown infection cases in Gauteng Province, South Africa, and its growth was rapid.

The form of New Coronavirus is still very serious.

As the first step of covid-19 detection, the importance of sample collection and preservation is beyond doubt.

The influencing factor is sample collection; If there is a problem with the collected samples, the results will be invalid regardless of the subsequent processing.

Selecting appropriate virus transport media and collecting flocked swab can improve the detection efficiency of new crowns.

Quick questions and answers about COVID-19 UTM Swab testing?

COVID-19 is a new variant of the very common viral family known as coronavirus, which can lead to respiratory tract infections, from the common cold to more serious diseases, such as severe acute respiratory syndrome (SARS). Although coronavirus is most commonly found in animal-like cattle, cats, and bats, in some cases, coronavirus can be transmitted and transmitted among humans, such as COVID-19 and SARS, of which nearly 8000 people were sick when they broke out in 2003.

According to the information currently shared by the new crown virus database GISAID, the number of mutation sites of the new crown virus Omi Keron mutant strain is significantly more than that of all the new crown virus mutant strains that have been circulating in the past two years, especially in the virus spike (Spike) protein mutations. . It is speculated that there may be three reasons for its emergence:

(1) After being infected with the new coronavirus, patients with immunodeficiency have undergone a long period of evolution in the body to accumulate a large number of mutations, which are transmitted by chance;

(2) a certain animal group infection New coronavirus, the virus undergoes adaptive evolution during the spread of animal populations, with a higher mutation rate than humans, and then spills into humans;

(3) This mutant strain has continued to circulate for a long time in countries or regions where the mutation monitoring of the new coronavirus genome is lagging. , Due to insufficient monitoring capabilities, the intermediate generation viruses of its evolution could not be detected in time.

The genome analysis of the Omi Keron mutant strain showed that its mutation site does not affect the sensitivity and specificity of mainstream nucleic acid detection reagents in my country.

The mutation sites of the Omi Keron mutant strain are mainly concentrated in the highly variable region of the S protein gene.

The nucleic acid detection reagent primers and probe-target regions were published in the eighth edition of the "New Coronavirus Pneumonia Prevention and Control Program" (China CDC Virus The ORF1ab gene and N gene released by the disease to the world).

However, data from multiple laboratories in South Africa suggests that nucleic acid detection reagents that detect the S gene may not be able to effectively detect the S gene of the Omi Keron variant.

Yes,’ if you’re going to a public place, it’s recommended to wear a mask. As long as the nose and mouth are covered, a scarf, handkerchief, or homemade non-medical mask can play a protective role.

It’s really important to wash your hands before and after putting on a mask.

Virus Test For COVID-19

In this article：

symptoms;

Swab Test;

COVID-19 is an infectious disease,a respiratory disease.

COVID-19 variants_Omicron

The new findings indicate that the new mutation of COVID-19, Omicron, spread earlier than everyone thought, and the scope is wider.

We must do a good job in vaccine injection and virus swab testing is the top priority.
According to the Associated Press, on Tuesday (November 30), the new findings have clearly shown that Omicron has entered many countries before the world has created its own protection system for Omicron.

The Spanish Institute of Public Health Service and Natural Environment (RIVM) detected Omicron in virus samples on November 19 and 23.

According to the World Health Organization, South Africa first reported this type of mutant virus on November 24.

At this stage, it is still not clear where this type of mutation first occurred, nor how infectious it is, but this has not prevented some countries from rushing to implement travel restrictions, especially for tourists from southern Africa.

This measure has been criticized by South Africa, and the WHO has also expressed its resistance, feeling that its actual effect is relatively limited.

The latest developments have also become increasingly clear that the travel ban cannot prevent the spread of new mutations.

The German government stated that they had seen Omicron in a man who had neither been to Africa nor had any knowledge of anyone who had contracted this type of virus.
The World Health Organization reminded on Monday that the risk of Omicron’s worldwide spread is “very high”, and initial direct evidence suggests that it is likely to be more infectious.

The COVID-19 pneumonia epidemic broke out for the first time nearly two years ago, and at this stage, the world’s response at many levels is similar to the disorder two years ago. Including random implementation of travel restrictions, and the lack of grasp of where there are risks and where there are risks.

Senior officials from all over the world try to clear everyone’s fears, saying that their vaccines are still a better way of defense. Be sure to continue to work hard to make vaccination spread all over the world. At the same time, do a virus swab test.

However, regarding the effectiveness of vaccines against Omicron mutations, although the President of the United States is also urging vaccination, the White House President’s medical consultant and the top infectious disease expert in the United States told the ABC TV program on Monday that the experts look forward to one or two in the future. Understand within a week.

What is the maintenance level of the current COVID-19 vaccine against this new mutation? Don’t know yet. But what we can do is to do a good job of virus swab testing and prevention. For example, go out less and party less.

COVID-19 symptoms;

The symptoms of COVID-19 are likely to include dysosmia, high fever, dry cough, dyspnea, chills, headache, muscle pain, sore throat, hematoma, or runny nose. At the same time, it is manifested as conscious fatigue, weakness, and weakness.
This situation may happen 2-14 days after you touch the virus that causes COVID-19.
Not all COVID-19 patients have all of these symptoms, and some people have no symptoms. That is an asymptomatic infection.
Even after recovering from COVID-19, some people are still likely to have unforgettable illnesses, such as fatigue, dry cough, or joint pain. The long-term physical and mental health hazards are unclear, but they may cause permanent damage to the cardiovascular system, lungs, or other human organs. This is more likely to occur in people with more serious illnesses, but it is more likely to occur even in people with milder illnesses.
If you have symptoms, please take a swab. If you have questions or concerns about a medical condition, please consult your health service provider.

About COVID-19 Swab Test

The new crown virus has mutated continuously.

From Delta to Omi Keron, the COVID-19 virus has continued to mutate, and the global epidemic is prevalent at a high level.

Canada announced that all entry personnel from all countries except the United States are required to be tested for the new coronavirus.

At this time, whether you are leaving the country or entering the country.

I even worry or doubt whether I have contracted the coronary disease.

Perhaps understanding the new coronavirus test has become a compulsory course for most people.

What is the new crown swab test, how to collect a nasopharyngeal swab?  Is nasal swab sampling painful?  If your test result is positive, what do we need to do?  Why do most virus tests choose to flock swabs? Is nasopharyngeal swab accurate? Should you be tested for nasopharyngeal swab samples?

We talked with Dr. Li of Cell medical to learn more.

What is the COVID-19 test and what are the test methods?

Nucleic acid detection (RT-PCR Test) method, antibody detection, and antigen detection.

A swab test simple, effective, and fast way to detect COVID-19.

Including nasopharyngeal swab testing and oropharyngeal swab testing.

Medical staff will use flocked swabs to take samples from the nose and throat and put them into the virus sampling tube.

There are two types of swab sample testing: molecular test (PCR) and antigen test.

How to perform a COVID-19 nasal swab test?

The COVID-19 nasal swab test involves inserting a 6-inch flock (a long stick with a very soft brush) into the cavity between your nose and mouth (nasopharynx).

The medical staff inserts the flocking swab into each nostril for about 15 seconds and rotates it several times to collect enough samples for testing.

The samples are then sent to the laboratory for testing, and our test results are usually known within or within the next day

Since the nasopharynx is in a sensitive position of the body, it will produce a lot of very strange sensations.

On the one hand, the swab is inserted deeply into your nose and it irritates the lacrimal glands.

At this point, you don’t know if you are moved to tears or you are crying in pain.

The nasal swab test is not very painful, but it is very uncomfortable. Some people may have nausea during the nasopharyngeal swab test. Nasal swab painful.

Because the swab will also touch the back of your throat, this reaction is normal.

Whether it is tearing or nausea, nasal swab testing is a common phenomenon.

Don’t worry, everything is normal.

Are there other types of COVID-19 swab test methods available?

Yes, an oropharyngeal swab is one of the options.

Of course, if you want to experience another feeling, an anal swab test is also a good choice.

But they are not as sensitive as the COVID-19 nasal swab test.

Israel’s development of the new coronavirus “saliva detection method” saliva detection still needs scientists to confirm on a larger scale. There is no conclusion yet, but it is promising.

In addition to nucleic acid testing for the detection of viral genetic material, there is also antigen testing.

Currently, nasal swab testing for COVID-19, including nucleic acid testing, is still the best choice.

How about the covid test kit at home? Are their results reliable?

The home covid test kit sounds very attractive.

Home covid test usually refers to individuals collecting samples of themselves or their family members through sampling swabs.

We put the collected samples in test tubes with a virus transport medium, and then transport them to the testing facility.

Although you can use the Home covid test kit to test COVID-19 safely and comfortably in your own home.

However, Dr. Li suggested that it should be carried out at a professional testing institution.

Because the quality of the samples we collect and the integrity of the samples during transportation will affect the sampling results.

How accurate is the nasal swab test for COVID-19?

How to obtain a precise nasopharyngeal swab specimen?

Polymerase chain reaction (PCR) uses a piece of DNA as a template.

Then, with the participation of DNA polymerase and nucleotide substrate, the DNA is amplified to a sufficient amount for structural and functional analysis.

Pcr nasal swab test can be said to be very sensitive.

Scientists use PCR technology to amplify a small amount of RNA in the sample into deoxyribonucleic acid (DNA) and replicate it until COVID-19 (if present) is detected.

The following may affect the accuracy of PCR nasal swab sampling.

1. Smoking, drinking or chewing gum 30 minutes before use may also interfere with the test results.

2. Touching the swab with the hand or other objects and using the tip of the cotton swab will affect the accuracy of the detection.

Of course, the professionalism of the most important sampling personnel, we have to choose a professional testing agency for testing. And professional VTM Kits.

What should I do if the new coronary pneumonia nasal swab test is positive?

Very bad news!

If the COVID-19 nucleic acid test is positive, a single room isolation treatment should be carried out immediately.

Consultation by in-hospital experts or attending physicians will conduct multiple tests.

Under the premise of ensuring safety, the patient is safely transferred to a designated hospital for diagnosis and treatment.

Don’t worry. You need to actively cooperate with treatment

Otherwise, life is likely to be in danger, and large-scale infections will also occur.

In addition, proper physical exercise should be carried out in life to enhance the individual’s immunity. Colds and fatigue should be avoided.

Don’t do strenuous exercise, so as not to aggravate the disease.

A friend around me was infected with COVID-19. But my nasopharyngeal swab was negative. Is there any way to confirm that I have had it or am I immune to it now?

Certainly.

Antibody test, also called serological test, can detect the antiviral protein IgM and IgG antibodies produced by your immune system in the blood.

What are the types of samples for serum antibody testing?

It is generally blood, including serum, plasma, and whole blood.

Covid Swabbing

Speaking of a Covid sampling Swab. We believe everyone will not be unfamiliar at this time. Because the detection tool used at this time is a possible sample.

Sample swabs directly contact our human organs, such as nasal swabs and throat swabs for testing. Therefore, the selection of the material of the sampling head is very important, and the material of the sampling head is related to the detection of the test.

Flocked swab Sample with the large amount and release amount, a large number of materials contain substances that are difficult to affect dye detection.

Omi Keron strain Covid Swabbing

The team of Professor Huang of Nankai University discovered this through big data modeling and analysis.

The infectivity of Omi Keron is about 37.5% higher than the infectivity of the new crown mutant strain Delta.

The Netherlands and Brazil both reported cases of infection with the Omi Keron strain of the new crown virus on the 28th.

To reduce the spread of the Omi Keron strain, all the people in Bots have recently appeared in the agency. The movement has a new crown for passengers in Bonawana, Malawi, Lesotho, Swaziland, Namibia, Mozambique, and Zimbabwe. Virus detection.

On the 28th in Hubei Province, two cases of Miokeron strain occurred in the capital of Ottawa, Canada.

Following reports of Omi Keron infections in some countries including a week later, this strain was infected with a mutant strain that “needs attention” on the 26th.

The United Kingdom, Germany, Italy, Russia, and Australia successively reported cases of infection with this strain on the 2nd and 28th. Ireland, New Zealand, Australia, the United Kingdom, Canada, the Netherlands, and the Czech Republic have also reported relevant cases.

For the spread of the virus strain, many countries have prepared measures and taken protective measures.

How to obtain a nasopharyngeal swab specimen?

Posted on by

How to obtain a nasopharyngeal swab specimen?

Overview.

Nasopharyngeal swab specimen collection of respiratory mucosal surface specimens is a method for the diagnosis of Covid-19 novel coronavirus in adults and children.

This operation can also detect patients with suspected respiratory infections caused by other viruses and bacteria.

There are no special contraindications for nasopharyngeal swab specimens. However, clinicians should treat the following conditions with caution: the recent history of nasal trauma or surgery, severe nasal septum deviation, chronic nasal obstruction, and severe coagulation.

Preparation for nasopharyngeal swab specimen sampling.

The nasopharyngeal swab is a special sampling tool, which consists of a sampling head made of soft plastic or flocked nylon. In addition to nasopharyngeal swabs, operators also need personal protective equipment (PPE) such as isolation gowns, non-sterile gloves, protective masks, and face shields.

Before starting to use, please make sure that all virus sampling tubes are labeled, and the analysis application form is filled incorrectly.

Nasal Swab Sampling Steps

We recommended that patients with suspected Covid-19 type coronavirus infection wear masks.

The patient took off the mask and blew his nose with a paper towel to remove excessive secretions from the nasal passages.

Take out the tissue. Slightly lift the patient’s head so that it can wipe into the nasal passage. Ask the patient to close his eyes to alleviate the slight discomfort caused by the operation.

Along the nasal septum, gently push the swab above the bottom of the nasal passage forward until you feel a sense of resistance indicating that the swab has reached the nasopharynx.
Insert the swab in the nostril parallel to the upper jaw.

If resistance is encountered during pushing the flocked swab, the scraper should be withdrawn, try to adjust the angle and then push again, at the same time closer to the bottom of the nasal passage.

The depth of the nose insertion should be equal to the distance from the nostril to the opening of the external auditory meatus. CDC recommends keeping the sampling head for a few seconds after it reaches the nasopharynx, allowing the sampling head to absorb the secretions, and then slowly rotating the swab to discharge it slowly (people who have done nasopharyngeal swabs will appreciate which kind of sourness Cool feeling). Your institution may also recommend sampling for a few weeks after exiting the spin. Ask the patient to wear a mask.

Nasopharyngeal swab specimen processing.

Open the sampling tube with virus transport medium, put in the flocking swab, fold out the sample tube in the groove, and discard the tail. Tighten the label sampling tube cover, and wipe the sampling tube with a sterile wipe.

Then place the sampling tube in the biohazard bag opened by the assistant. Some departments may require you to put the samples back in their original packaging and then send them for inspection. According to CDC guidelines, process the swab sample directly, or put the sample in a preservation solution or store it at room temperature.

Do a good Virus Swab Test, Epidemic is not over yet.

Winter has arrived, affected by the new crown pneumonia epidemic in Europe. Such as Cuba, the Netherlands, Germany, the United Kingdom, etc., the epidemic is continuing. More and more European countries have recently stopped restarting and tightening anti-epidemic measures. After the outbreak, European experience proved that: “Dynamic zero adjustment has been mastered” . “continuous changes in temperature rise have been controlled.” Advantages and captures “return to zero” and “constantly switch between limiting adjustments”.

COVID-19 mutant virus Omi Kiron strain has spread to all provinces in South Africa.

South African President Ramaphosa said on the 28th that in the next few weeks.

There may be a fourth wave of new crown epidemics in South Africa.

And the public should do a new crown virus sampling swab test as soon as possible and get the new crown vaccine.
In the evening, Ramafosa said in a televised speech that in the past 7 days.

The number of confirmed cases of the new crown in South Africa has risen to an average of 1,600 per day, while the positive rate of new crown virus testing in South Africa has risen from approximately 2% to 9% in the previous week.

If the newly emerging confirmed cases continue to rise, South Africa may enter the fourth wave in the next few weeks.
Lamafosa said that the recently emerged mutated virus, Omi Keron virus, has spread to all provinces in South Africa.

At present, immunization is still the most important means of protecting oneself and others.

The emergence of the Omi Keron virus has sounded a wake-up call for the whole world.

Several countries, including South Africa, have recently reported confirmed cases of Ome Keron, and the World Health Organization listed the virus as a “variety of concern” on the 26th.

About the European epidemic

European experts believe that the recent occurrence of the “epicenter” of the global epidemic in Europe is related to factors such as disease awareness, premature “unblocking”, and insufficient vaccines. The most critical factor-the effect of excessive pendulum movement, which swings from side to side at a strict angle. We must do a good job in the swap test of the COVID-19.

Herd immunity？

Doing a good job of a virus swab test, testing and vaccination is the top priority.

At the beginning of the disease outbreak, Patrick Valence, the chief scientific adviser of the United Kingdom, put forward the theory of “herd immunity”. Now in the world, the EU has completed 7% of the population protection range of about 6%, and still cannot solve the fourth wave of epidemics.

The proliferation of medical resources film festivals appeared. The incidence is higher in the northern region. 79% of people abroad have received local injections. The number of the above cases has reached 9.8 million, and the proportion of the British population is 14.6%. New highs since the beginning of winter, the peaks of the virus wall in various states have taken turns, and no emergencies have occurred. The theory of “in the iron face, group immunity” has broken down.

“Coexisting with the Virus” Nonsense.

Mistakes in the fight against the virus continue to disrupt growth and even increase risks. From the beginning of the new century, the “labor shortage” and supply chain crisis in many countries can end this. Over the past year or so, Europe has had to return and fall in the policy choices of “severe cold and epidemic prevention” and “economic recovery”. The vicious circle of “high control-unraveling-epidemic rebound-re-management”.

However, as the life expectancy of relevant countries or regions has dropped significantly, the problems that gradually emerge after the outbreak of the disease will have a more severe and instantaneous impact.
It has achieved great success by adhering to the goal of zero-clearing the epidemic. Even eager to announce “coexistence with the virus”, trying to adopt a third response method under the situation of repeated zero-sum dynamics.
But, there will be such a road there? The result of choosing to “coexist with the virus” at this stage is nothing more than harming more people’s lives.

Disposable virus sampling tube

Disposable virus sampling tube

At present, the form of New Coronavirus is still very serious.

As the first step of covid-19 detection, the importance of sample collection and preservation is beyond doubt.

The influencing factor is sample collection; If there is a problem with the collected sample, the result is invalid regardless of the subsequent treatment.

Selecting appropriate virus transport media and collecting flocking swabs can improve the efficiency of new crown detection.

Almost all virus preservation solutions on the market contain non inactivated viruses directly, resulting in high infection risk for sampling, transportation and testing personnel.

Therefore, the front line of epidemic prevention needs to be able to inactivate virus samples directly.

At 37 ° C, we compared the preservation effects of cell medical (Dongguan) preservation solution containing guanidine hydrochloride and guanidine isothiocyanate with that without guanidine salt on avian coronavirus.

After 1-7 days of storage, under the same condition of 37 ℃, the preservation rate of virus nucleic acid was basically maintained at 100% when it was preserved with cell medical (Dongguan) preservation solution;

·Use virus preservation solution that can protect the sample from high temperature inactivation.

The results showed that high temperature inactivation had no significant effect on the integrity of coronavirus nucleic acid when coronavirus nucleic acid samples were preserved with high temperature inactivator.

The virus preservation solution developed by Cell medical (Dongguan) company is divided into inactivated and non inactivated. Different preservation solutions can be selected according to different test requirements and test conditions. If you have any questions or needs, please call us. Choosing cell medical (Dongguan) virus transport media solution in China is your right choice.

Furan compounds (guanidine isothiocyanate or guanidine hydrochloride, etc.) are typical protein denaturants.

They are often used to extract cell lysis in nucleic acid and inactivate virus. However, the furamethoxam component does not have the ability to work at room temperature.

Because the ability to preserve viral nucleic acid is easy to lead to sample degradation, it is not suitable for preserving new coronavirus samples. Therefore, it is strongly recommended that you choose the preservation solution without guanidine salt.

To this end, we call on the majority of medical personnel to select non inactivated virus transport media if they take samples for the purpose of nucleic acid detection and do not need to culture live viruses.

Vtm Swab | Virus Transport Medium with Sampling Swab

Vtm Swab | Virus Transport Medium with Sampling Swab

Use a virus medium that inactivates the virus.

At present, covid-19 detection is mainly to detect viral RNA, which needs to divide the virus.

Therefore, as long as the integrity and stability of virus nucleic acid can be guaranteed, there is no need to preserve live virus.

Therefore, in the current situation of fighting COVID-19, it is ideal to inactivate the virus while collecting samples. Some manufacturers have also introduced inactivated transport medium, but its inactivating component is guanidine salt.

The results showed that the salt forming component storage solution had insufficient storage capacity for viral nucleic acid at room temperature, which was easy to cause sample degradation.

Therefore, we recommend the use of virus preservation solution containing non guanidine protein denaturants.

The volume of solution in the sampling tube should be appropriate.

① When sampling each sample separately, we recommend that you select a virus sampling tube containing 1ml storage solution to ensure the correct storage capacity. It can not only meet the downstream needs of nucleic acid extraction and detection. Compare with 3ml storage solution. Triple the virus concentration!

② For large-scale preliminary screening and mixing test, we should choose to put the samples of 3-5 people into the sampling tube.

·Use a virus preservation solution that can transport and preserve samples at room temperature.

If the delivery temperature does not meet the standard, the viral nucleic acid may degrade, resulting in a “false negative” test result!

On the contrary, if cell medical uses a virus storage solution that can transport and stably store virus nucleic acid at room temperature.

We solved the problem of sample transportation and improved the accuracy of test results.

·Use virus preservation solution that can protect the sample from high temperature inactivation.

However, the research reports of Beijing Center for Disease Control and prevention in the Journal of “clinical chemistry” and Beijing Preventive Medicine Research Center show that high temperature inactivation can lead to the degradation of virus nucleic acid, thus reducing the detection rate of virus nucleic acid. Therefore, The false negative rate of New Coronavirus nucleic acid detection is high.

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.

Nasal Swab VS Oral Swab

Some customers inquire:

Are nucleic acid tests all about poking the throat?

Will you poke your nose?

“Poke the nose” through the Internet is more accurate,

is that true?

Don’t panic, let’s learn about it with Xiao Liu from Cell medical!

 

When doing nucleic acid testing,
There is a very important project,
Just do a throat swab
There are two types of throat swabs-nasopharyngeal swab and oropharyngeal swab sampling.

Currently
Most hospitals use
Oropharyngeal flocked swab
Because-it is the most convenient to collect samples and less painful.

But there are rumors,
The detection rate of nasopharyngeal swabs is higher,
is that true?
Yes! Yes! Yes!
Studies have shown that the poison load of nasopharyngeal swabs in patients infected with the new coronavirus is much greater than that of oropharyngeal swabs.

Focus on:
Wear a mask when you go out!
Wear a mask when you go out!
Wear a mask when you go out!

The important thing is said three times!

 

Nucleic acid detection, antibody detection

confuse?

After the new coronavirus infects the human body, it will first reproduce in the respiratory system. Therefore, it can be determined whether the human body is infected with the virus by detecting the viral nucleic acid in the sputum and nasopharyngeal swabs.
To
After a period of infection, usually 7-10 days, the human body will produce specific antibodies against the virus. IgM antibodies will appear first, and then IgG antibodies will appear. Therefore, detecting these specific antibodies can determine whether the human body has been infected with the virus. ,

If allowed,

You can, according to your own tolerance,

Choose whether to do a nasopharyngeal swab or an oropharyngeal swab.

in addition,

The serum antibody test is to draw venous blood,

No need to fast!

The flocked swab deposits nylon fibers on the surface of the medical ABS rod in order in a certain direction through the electrostatic field to form a brush layer.

Flocked Swabs for Sample Collection

Flocked swabs for sample collection

The flocked swab deposits nylon fibers on the surface of the medical ABS rod in order in a certain direction through the electrostatic field to form a brush layer. The layers are fully parallel and perpendicular to the surface of the internal rod.

The brush head can be used for Virus cell collection.

It can be used for sampling the natural cavities of the human body such as oral cavity, nasopharynx and laboratory detection.

Why flocked swabs?

The flocking swab deposits nylon fibers on the surface of the medical ABS rod in order in a certain direction through the electrostatic field to form a brush layer. The layers are fully parallel and perpendicular to the surface of the internal rod. The brush head can be used for DNA collection. It can be used for sampling the natural cavities of the human body such as oral cavity, nasopharynx and laboratory detection.

So that there is no absorption hole in the sampling area of the whole sampling swab.

And the sampling sample will not be dispersed and retained in the fiber, which is conducive to faster and more efficient elution.

Traditional cotton swabs can not completely collect and elute samples, while flocking swabs can elute 95% of samples.

Therefore, the use of flocking swabs has great advantages for various sample collection applications.

Nasopharyngeal flocked swab;

Flocked swabs have some advantages;

1. Sampling is comfortable and easy to use;

Flocking swabs now basically use “spray technology”, which vertically attaches millions of nylon fibers to the head of medical ABS swab rod through the flocking process of electrostatic charge.

The function of the vertical nylon fiber is similar to that of a soft brush. The use of this soft brush in the sampling process makes the user feel free of foreign objects. At the same time, the flocking swabs used in different parts adopt different breaking points, and the rod adopts different thickness to make the softness different.

For example, the nose swab is thinner and softer at the upper end of the rod, and the breaking point is longer, which fully conforms to ergonomics.

2. Flocked swab samples release more;

The capillary action between nylon fiber bundles promotes the strong hydraulic absorption of liquid samples. The sample is kept on the surface to make elution easier. It is much larger than the traditional winding cotton swab. The experimental research shows that the collection and release of flocking swab can reach 95% of the sample, while the cotton swab is only about 20%.

Because most of the samples collected by the cotton swab are easy to be intercepted in the fiber matrix layer of the head during release, it is not easy to release or release a small amount.

3. Flocking swab has biocompatibility and is an ideal choice for PCR;

In order to limit the damage to the sample and improve the accuracy of detection, while the flocking swab is PCR compatible and does not contain RNase and DNase.

Operation method of flocked nylon swab:

Take the sampling method of oropharyngeal swab as an example;

1. First, ask the patient to sit down, then let the patient tilt his head back, open his mouth, and make an “ah ~” sound.

2. The sampler fixed the patient’s tongue with a tongue depressor, and used a flocking swab to cross the root of the tongue to the posterior pharyngeal wall, tonsil recess, lateral wall, etc.

3. Wipe repeatedly for 3 ~ 5 times to collect mucosal cells.

4. Slowly take the swab out of the mouth, vertically put it into the virus preservation solution, break the tail of the swab, and tighten the sampling tube to avoid leakage.

5. Send to the laboratory for testing as soon as possible.

Swab flocked matters needing attention:

1. The swab shall be placed vertically in the sampling tube, and shall not be wiped to the bottle mouth to avoid pollution.Viral Transport Medium.flocked swab copan.

2. It is best to send it or send it to the laboratory for inspection on the day of sampling.

3. Before submission for examination, it must be verified that the specimen is consistent with the submission form. The appearance of the sampling tube must clearly write the patient’s name and basic information.

4. The submitted samples must submit (or submit the electronic version in advance) screening information form, inspection form and other materials.
