As we learn more about COVID-19,

Protect yourself and others: COVID-19, do a new crown swap test and get a new crown vaccine.

On this page, you will learn:
What should we pay attention to during holiday gatherings?

Of course, Cell Medical recommends minimizing unnecessary gatherings. For you and your family and friends.

The latest mutation of the new crown epidemic has increased the risk of transmission.

Faced with the epidemic, but the company arranges to travel, what should I do?

Please do a nasopharyngeal swab test before going home.

What should we pay attention to during holiday party activities?

Cell medical company offers a variety of ways to enjoy the holiday tradition and protect your health.

We encourage colleagues in the United States to take the following steps to make your holiday gatherings safer.

To do a nasopharyngeal swab test, maybe we have to confirm whether we have been to a high-risk area before the party. Whether to carry the new crown virus, a flocking nasopharyngeal swab test is the best choice.

Take a COVID-19 swab test so you can find out before you go. You can go to the test site or use the home test program. Of course, we recommend that you go to a professional testing agency for nasopharyngeal swab testing.

Some locations may be closed on or around holidays. Check it a few hours before departure.

vaccination. The best way to ensure the safety of your family and friends is to get vaccinated if you and your family are eligible.

If you feel unwell, please stay at home. If you have symptoms of COVID-19 or a positive swab test, please stay at home and away from others. And notify the government personnel of the first pass to conduct another virus test, and do not attend the party.

Of course, nowadays, you must wear a mask before going out. This is for the health of you and your family and friends.

You need to wear a mask when taking public transportation, including buses and airplanes.

Of course, party us

Gather in an outdoor or well-ventilated place.

According to experience, the most likely way of transmission of the virus is through saliva or droplets. Therefore, during the epidemic period, try to avoid contact with others and face-to-face conversations.

During the party, we should pay attention to eating clean cooked food and boiling water.

Ask the party host to try not to choose to eat some wild, uncommon, and strange food.

At the same time, the weather is volatile, and your handsome colleagues pay attention to adding or removing clothing.

Finally, Cell Medical recommends minimizing unnecessary gatherings.

 

The latest mutation of the new crown epidemic has increased the risk of transmission.

Infectivity may increase by 500%! Powerful mutant strains broke out in various countries in the world!

On the 27th local time, several countries and regions, including the United Kingdom, Germany, Italy, and Israel, discovered the new variant “Omicron” (Omicron) of the new crown.

At this stage, countries around the world have tightened their epidemic prevention measures at different levels.

The Israeli government announced that it will gradually prohibit all foreigners from entering the country on the evening of the 28th local time. Resolutely putting an end to the spread of the “new coronavirus mutant strain Omi Keron” has become a new starting point for epidemic prevention worldwide.

Authoritative American experts think: “The infectivity of the new mutant strain may increase by 500%.”

On November 27, WHO announced that the new mutant strain discovered in South Africa was named Omicron.

On the 26th local time, the Federation of American Scientists emphasized that in comparison with the Delta mutation, the total number of “bad thorn gene mutations” in the new mutation was twice that of Delta.

 

“The B.1.1.529 variant is likely to have a strong charisma of 500%, which is by far the most surprising statistic.”

On the 26th local time, the United States announced that it will gradually restrict the citizens of South Africa and seven other non-US African states to travel to the United States from the 29th.

Previously, the United Kingdom, the European Union, and many other places have called for the suspension of flights originating from African countries.
The new mutant new coronavirus “Omi Keron” first discovered in South Africa has spread rapidly

According to foreign media reports, in Gauteng Province, where the population of South Africa is more concentrated, 90% of the recent increase in virus cases is related to this strain. The Israeli Ministry of Health issued a statement on the 26th stating that the first case of “Omi Keron” virus infection was found. The case came from Malawi, Africa, my country. The Belgian Minister of Environmental Health, Van den Brock, confirmed that the host country has found the infection case of the mutant strain “Omi Keron”. According to reports, this is also the first diagnosed case in Europe.
The first case of Omi Kiron strain infection occurred in Italy…

The spread of new mutant strains is astonishing, which has aroused great vigilance in all countries!!!

Facing the epidemic, but the company arranges to travel, what should I do?

Of course, the best option is to refuse a business trip. But often this is not something we can decide.

Everyone is based on the following suggestions to alleviate the spread of COVID-19 to protect themselves and others.

The more processes you use to mitigate the spread of COVID-19, the safer you will be. When it comes to avoiding the spread of COVID-19, no step is perfect.

1. Reduce your risk of COVID-19

2. Actions and natural environment maps with lower risk and higher risk.

3. Proposals for participants and theme event planners: COVID-19

Vaccination. The COVID-19 vaccine is one of the appropriate ways to avoid being infected or spreading COVID-19.
If you are not vaccinated (including children)

Maintain a minimum distance of 6 inches from people from other homes.
When you cannot maintain a 6-inch distance from others, please wear a mask in the room and outdoors.

If you are vaccinated or not vaccinated, Cell medical strongly recommends that you:

1. Wash your hands frequently, maintain your hygiene, and open windows every day for ventilation

2. Try not to go out, if you go out, try to wear a mask

3. Try not to hold parties and avoid contact if it is not necessary

4. Pay attention to eating habits, eat more fruits and vegetables, exercise, and keep a good sleep

5. Cover your nose and mouth when sneezing, and don’t spit anywhere

If possible, work from home.
Clean and disinfect the surface.

Please do a nasopharyngeal swab test and isolation work before going home. For the health of you and your family.

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.

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?

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.

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.

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.

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.

flocked swabs for sample collection

flocked swabs for sample collection

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.

To do a good job of normalization prevention and control, we should accelerate the improvement of detection capacity and carry out nucleic acid and antibody detection on a large scale.

This is not only conducive to accurate prevention and control, maintaining people’s health, but also conducive to the rational flow of personnel and promoting the full resumption of work and production.

Nasopharyngeal swabs are used for nasopharyngeal sampling of respiratory diseases such as COVID-19, influenza, avian influenza and hand foot mouth disease.

For nasopharyngeal Swab Pcr Test, Pay Attention to the Following Points:

1. Please do not take antibiotics a few days before rhinitis swab Pcr Test.

2. Do not rinse your mouth with disinfectant or smear the lesion a few hours before making a nasopharyngeal swab.

3. Don’t eat, smoke or drink a few hours before making a nasopharyngeal swab.

4. If the patient’s turbinate is hypertrophic and the nasal tract is narrow, and the insertion resistance of nasopharyngeal swab is relatively large, we can’t use force rashly. We can try to use the other nasal cavity, or directly use oropharyngeal swab to collect.

5. After sampling, gloves shall be replaced, hands shall be disinfected, and disinfectant shall be sprayed on the place where the patient has touched.

In special times, you should also remember to wear a mask and do a good job in personal hygiene. Once you find a virus, please isolate it to avoid re infection.

About Nylon Flocked Nasal Swab

Cell medical produces a special flocking swab for coronavirus collection, which has excellent sample collection and release ability, can quickly adsorb micro samples, and has a high release timeliness rate. The increase of the number of targets is helpful to improve the sensitivity of rapid diagnostic test.

COVID-19 nucleic acid detection is one of the criteria for the diagnosis of cases. It is the key to early detection, early diagnosis, early isolation and early treatment, as well as the basis for isolation treatment of infectious source and medical observation of close contacts.

Nasal Swab Virus Sampling Kits.

Nasal swabs PCR test process

At present, most virus nucleic acid detection kits use fluorescence quantitative PCR to determine whether the sample contains virus nucleic acid by detecting the accumulation of fluorescence signal. So, what steps do nucleic acid detection need to go through? To sum up, there are five steps: sampling, sample retention, preservation, nucleic acid extraction and computer detection.

sampling

Collect human secretions. Wipe the nasal cavity or posterior pharyngeal wall and bilateral tonsils with nasopharyngeal swab or pharyngeal swab

Sample retention

Immerse the swab head into the cell preservation solution, and tighten the tube cover immediately after breaking the tail

preservation

Good news, recently, Health Canada approved covid-19 rapid test equipment. From now on, this equipment can be used for virus testing all over Canada, and the results can be obtained in 15 minutes at the fastest!

The number of outbreaks in Canada has soared, and the pressure of virus testing has also soared! Ontario and other places once had to queue up for more than 4 hours to wait for virus testing.

This will help alleviate the increasing number of confirmed cases and the need for virus testing. Best of all, the rapid test device can be managed by trained professionals in pharmacies and other places, without having to test the results through the laboratory.

At present, most covid virus tests in Canada are carried out in public health clinics, and then the samples are sent to the laboratory for analysis.

This process may take several days.

Bcause some cities are facing the situation that testing centers queue up for hours.

How much do you know about COVID-19 antigen detection technology?

In late spring and summer of 2020, the COVID-19 epidemic was initially resurgent beyond all expectations, and unexpectedly came back with a strong attitude.

“COVID-19” On August 26, 2020, in order to control the spread of the epidemic.Abbottswab.

In addition, the federal government will spend $760 million to buy 150 million copies of reagents and transport them to nursing homes and schools in about a month.

Antigen detection.

By the end of October 2020, with more similar tests under way and waiting for emergency approval.

Three more antigen test kits have obtained the emergency use authorization (EUA) of the US Food and Drug Administration (US FDA), and the total number has reached 7.

In addition, although the World Health Organization was unwilling to do so at first.

It also approved the use of two antigen detection kits following the emergency authorization of the U.S. Food and Drug Administration in September and October 2020.

In the invention and transformation caused by covid-19 pandemic, detection technology has become a hot spot of biotechnology and engineering innovation.

In addition, more extensive measures such as wearing masks, maintaining social distance, isolating and tracking contacts.

And faster and cheaper screening tests provided by Cell medical provide hope for people’s urgent need to combat this infectious disease and make progress.

Many places in the world that seemed to have controlled the epidemic in the early stage broke out again.

Which shocked public health experts and called on everyone to carry out rapid and frequent testing.

According to a report recently released by the Rockefeller Foundation.

If only to meet the testing needs of primary and secondary schools and nursing homes.

The United States should complete 200 million rapid tests per month by January 2021.

Although people tend to detect with higher accuracy, antigen detection with accuracy of only 70% .

People can also find infected persons omitted from previous tests through frequent detection. And provide sufficient accuracy for continuous screening.

According to Mara g. Aspinall, a practical professor and medical diagnostic expert at Arizona State University (ASU) in Tempe.

The co-author of the report, the number of tests required to screen the entire U.S. population may be twice that required by schools.

“Now it’s time,” Aspinall said. “We have an agreement and testing reagents. I hope the community can reduce the spread of the virus and control the epidemic again.”
