What to do before the swab test？

Why implement full coverage of DNA swab testing?

What should be paid attention to in DNA testing?

The latest statistics on the COVID-19  released by Johns Hopkins University in the United States on the 9th show that the cumulative number of confirmed cases in the United States has exceeded 60 million.

Nucleic acid detection is an effective method for precise prevention and control.

After the COVID infects the human body, it will multiply in the respiratory system.

Using a nasopharyngeal swab to detect sputum can determine whether the human body is infected with the virus, and can quickly and accurately “find out” the virus.

The recent spread of the epidemic has brought new pressure to epidemic prevention and control around the world. There are even reports of a country’s leader being positive for the new crown. Mexican president tests positive for coronavirus. The President of Paraguay has tested positive for the new crown. Poland: President tests positive for coronavirus. Brazil’s president tests positive for coronavirus. etc.

On the basis of continuing to perform nucleic acid testing on key groups of people, close contacts, etc., to identify the infection chain as soon as possible, block the transmission route, control the spread of the epidemic, and implement large-scale full nucleic acid testing, we must achieve early detection, early reporting, Early isolation, early treatment, active search for potential new coronavirus infections, and targeted prevention and control measures are also adopted to protect the health of the masses, ensure the rational flow of the population, and maintain the stable development of social and economic life order. It is very important. significance.

What methods are available for COVID swab testing?

Nucleic acid detection generally adopts the nasopharyngeal swab detection method, including nasopharyngeal swab detection and oropharyngeal swab detection.

At present, most hospitals and institutions in our city use oropharyngeal swabs.

This method is the least painful and more convenient to collect samples.

Is it painful to take a throat swab?

A throat swab is a method of collecting a specimen from the throat area, it is painless, mild nausea or sore throat method, which can be relieved or disappear quickly after collection.

Are DNA tests dangerous to humans?

There is no harm to the human body, only when the throat swab is collected, a slight foreign body sensation will be felt when the cotton swab enters the throat.

What should I pay attention to before and after the inspection?

Before detection

Before the nucleic acid test, it is best not to eat for 2 hours, otherwise, it will cause vomiting.
Do not drink water, smoke, drink, or chew gum 30 minutes before sampling.

Before the examination, reduce the number of swallowing movements, and do not do throat-clearing movements, such as expectoration and spitting.

For example: before the nasopharyngeal swab collection, the subject should provide the collector with the relevant past medical history or related matters.

Such as history of nasal surgery, nasal septum, blood disease, throat disease, or taking anticoagulant drugs.

Be sure to wear a mask before going to the test, take out the mask before the test, and put it on immediately after the test. You can prepare a spare mask, which can be replaced at any time after pollution.

Checking

When collecting oropharyngeal swabs, the subject should tilt his head back, relax as much as possible, take a deep breath, and open his mouth to make an “ah” sound, which will help reveal the throat, but symptoms such as irritating dry cough, nausea and vomiting may occur during this process.

Nasopharyngeal swab During the process of nasopharyngeal swab, symptoms such as swelling, itching, and sneezing may occur, which can be covered with a tissue or elbow.

After detection

Leave the collection site immediately after collection to avoid spitting and vomiting near the collection site.

You must pay attention to hand hygiene before and after the nucleic acid test.

You can wipe your hands with your hands, or you can use hand sanitiser, disposable alcohol, and disinfectant cotton pads.

 

Important reminder:

●Be careful to wear a mask, do not expose your nose and nose, do not take it off at will, or pull the mask to your chin.
●There should be an orderly queue, keep a distance of 1 meter, do not get together, do not gather.
●When waiting in line for a long time, pay attention to sun protection, sun protection, scientific hydration, and a reasonable diet.
● Try to avoid taking public transportation to the nucleic acid test sampling site.

The current situation of epidemic prevention and control is very complicated.
Every day, take care to protect your body.
Wear a mask and follow the epidemic prevention regulations.
Protect yourself and protect others at the same time.
New coronavirus pneumonia cases.
Please accept the general guidelines for prevention and control.
Daily Travel Prevention Control Guidelines.
Take the bus, take the subway.
To minimise contact, payment can be made using a transport card or a mobile app.
Avoid touching public facilities such as seats, armrests, car doors, and armrests with your hands as little as possible. If you do, do not touch your mouth, eyes, and nose directly with your hands, and disinfect your hands in time to avoid contact infection.

Hospitals and other places, after returning home, you should disinfect your outerwear.

This article
To talk to you in detail
Covid nucleic acid test!

But in the face of the “nucleic acid swab test”
This unfamiliar and familiar word
Do you have many questions?

Image source network

Do you want to do a nucleic acid test when you go back?

Will it be difficult to make an appointment for nucleic acid testing?

How long does it take to get the results of a nucleic acid test at the hospital?

Should I Swab My Throat or Nose for Rapid COVID-19 Tests?

To answer your questions.
Today.
I’m going to tell you.
Those things about nucleic acid testing.

01. What is nucleic acid detection?

At present, nucleic acid detection is the main method for laboratory diagnosis to determine whether a patient is infected with the new coronavirus. It can achieve early detection, early diagnosis, and early treatment. Real-time fluorescent PCR can be used to detect throat swabs, sputum or blood samples. to covid nucleic acid, or detected by viral next-generation gene sequencing.

simply put

Nucleic acid testing is done by

After collecting human secretions

Tested by the instrument

to see if we have the new coronavirus in our body

If so, the test result is positive

On the contrary, if it doesn’t, it’s negative.

02. How to test the COVID swab?

“Sir, oropharyngeal swab, nasopharyngeal swab, and anal swab, which one to choose?”

How do you do a nasopharyngeal swab?

Nasopharyngeal swabs must be performed with the patient sitting upright with the head in an upright position, as this allows for easy visualization and access to the nasal floor perpendicular to the central axis of the patient’s face.

Flocked Tip Swab Nylon Sterile Nasal Swab Stick

Flocked Tip Swab Nylon Sterile Nasal Swab Stick

Insert the swab into the patient’s nose and align it parallel to the nose and the base of the septum. As long as there is no obstruction in the nasal cavity, the swab continues to move in this direction until it reaches the nasopharynx, at which point the tester feels resistance.

Once the swab reaches the nasopharynx, a gentle rotation and two complete 360-degree rotations are recommended to allow secretions from this area to be absorbed.

Once the swab is removed from the patient’s nose, it is immediately inserted into a viral sample containing a viral transport medium. The handle of the swab extending through the opening of the vial was broken off to allow the tube to be closed.

So
Now that there are oropharyngeal swabs and nasopharyngeal swabs
Why add anal swabs?
To answer your questions
Let’s take a look at their respective advantages and disadvantages

The specific operation of the anal swab is as follows:

Soak a flocked swab in saline, insert it 2-3 cm into the anus, wipe from the folds around the anus, or rotate it gently inside the anus, and insert it into a test tube containing saline.

anal swabs

For fecal swab cultures, all of the above requires the use of sterile equipment and placing the swab in a sterile tube.

So
Now that there are oropharyngeal swabs and nasopharyngeal swabs
Why add anal swabs?
To answer your questions.
Let’s take a look at their respective advantages and disadvantages.

Oropharyngeal swab: relatively simple to operate, less irritating, suitable for large-scale screening. Therefore, the nucleic acid test of oropharyngeal swabs is mainly used in the screening of new coronary pneumonia for the epidemic-related population, which is used in the routine nucleic acid test clinic of the First Affiliated Hospital of NTU.

Nasopharyngeal swab: The technical requirements are high, the human body does not feel comfortable, and the accuracy rate is higher than that of the oropharyngeal swab. However, for some asymptomatic or mildly infected people, the condition recovers quickly after infection, and the pharyngeal nucleic acid may not be detected in 3 to 5 days.

Anal swab: high accuracy, reduce missed diagnosis. The study found that the duration of nucleic acid-positive feces or anal swabs of some infected persons is longer than that of the upper respiratory tract. Therefore, anal swab tests will be carried out for key groups such as isolation points or some imported overseas.

In conclusion.
The three swabs have different lengths.
If you have to test an anal swab.
Don’t be shy.
Whatever the swab,
It is a good swab that can accurately identify the virus.

During the outbreak of the new coronavirus pneumonia, while everyone is doing personal protection, they are also very concerned about the epidemic situation.

Originally, the social season in winter and spring was a period of the high incidence of common colds and flu, and the most important means to control the epidemic was to screen out the real patients with new coronary pneumonia from many respiratory patients.

The following small series will introduce some common virus sampling detection methods for you.

Nasopharyngeal swab

Collect nasopharyngeal swab specimens within 3 days of the onset of the patient as much as possible.

Measure the distance from the tip of the nose to the earlobe with a swab and mark it with your finger, insert the swab into the nasal cavity in the direction perpendicular to the nose (face), and the swab should be at least half the length from the earlobe to the tip of the nose so that the swab stays in the nose for 15 ~30 s.

Gently rotate 3 to 5 times, quickly put the swab into a sample collection tube containing 2 ml of lysis buffer (the same as the lysis buffer in the nucleic acid extraction kit) or a cell preservation solution containing RNase inhibitors, and insert the swab.

Then break the sterile swab rod near the top, screw the cap tightly and seal it with parafilm.

Oropharyngeal swab

Collect throat swab specimens from patients within 3 days of onset as much as possible. It is advisable to use a sterile flocked swab for sampling, wiping the posterior pharyngeal wall with moderate force, avoiding touching the tongue; quickly put the sterile swab into the collection tube used for collecting nasopharyngeal swabs, and break it near the top Sterile swab rod, screw cap tightly and seal with parafilm.

Anal swab (feces)

For patients with gastrointestinal symptoms such as diarrhea in the early stage of the disease, an anal swab should collect a stool sample (soybean size) of 3-5g.

The specimens were collected in a screw-cap specimen collection tube containing 2 ml of normal saline (RNase inhibitor can be added if available) and sealed with parafilm.

How to collect nasopharyngeal swabs

There is absolutely no need for the sampler to stand directly opposite the patient. Regardless of whether the patient is sitting or lying, right-handed patients can stand on the right side of the patient, and left-handed patients can stand on the left side for sampling operations.

The advantage of standing on the side is that if the patient has a cough, sneeze, etc., it can be avoided in time.

After the nasopharyngeal swab is passed through the nostrils.

It is perpendicular to the coronal plane of the head or the face and penetrates deep from the inferior meatus to the posterior wall of the nasopharynx, and it is enough to feel the wall.

The nasopharyngeal swab enters the nasal cavity to a depth of approximately the distance from the tip of the nose to the earlobe (see figure).

The “American Society for Microbiology Clinical Microbiological Specimen Submission Guidelines. ” We ask to twist the nasopharyngeal swab on the nasopharyngeal mucosa, hold it for 10-15 seconds, and then take out. Children’s cooperation is poor.

We generally take out the Flocked swab in three to five seconds after fully twisting it 2-3 times.

Except for paying attention to the depth of the swab. We should also note that there is always the habit of having the patient lift their head completely, bend the swab, and take a sample. This is wrong.

In fact, the above approach is wrong. This operation will cause the swab head to stay in an incorrect position. And the final sample obtained is not a standard nasopharyngeal swab specimen.

What is a Medical Swab

In the COVID-19 sampling, medical flocked swabs are the most commonly used testing method.

Application: oral mucosal cells, oral microorganisms, virus sampling and transportation, DNA/RNA collection, throat sampling, cervical sampling, nasopharyngeal sampling and other fields.

In addition, we can also use medical cotton swabs for the collection and transportation of DNA for paternity testing.

As well as the collection, preservation and transportation of flu specimens.

According to the material, medical swabs can be divided into cotton swabs, foam swabs, non-woven swabs, flocked swabs and other products. Among them, the market share of cotton swabs is higher, reaching 76%.

According to the application field, medical swabs include gynecological, cervical and vagina sampling swabs; oral, nose, and pharynx sampling swabs; laboratory test sampling swabs; virus and bacteria sampling; disposable sampling swabs; sterile cell sampling And other products.

However, due to the influence of new coronary pneumonia and the popularization of nucleic acid testing, the proportion of medical swabs used for specimen sampling is increasing.

With the continuous improvement of medical conditions in developing countries around the world, the application demand for medical swabs is on the rise.

In 2020, the global medical swab market will reach 400 million U.S. dollars, with an output of about 38.4 billion pieces.

Moreover, due to the development of the world economy, the price of medical cotton swabs has shown an upward trend.

Choose the right medical swab

Swabs are one of the most commonly used disposable devices in the medical industry. But how do you know which application to choose? We have put together a brief overview on how to choose the right medical swab for your specific needs.

Cotton swab

The tip of American pharmaceutical-grade spun cotton fiber has become the standard for applicators for all applications from basic patient care to crime scene investigation.

With strong water absorption capacity, softness, low cost and safety, the performance of the cotton swab is consistent and reliable.

However, it is generally not recommended to use cotton swabs for specimen collection.

why? The characteristics of this natural material prevent the sample from being effectively released, and the naturally occurring fatty acids in this material interfere with the processes used in microbiology and DNA extraction and have proven harmful to organisms.

Rayon cotton swab

"<yoastmark

Rayon is a synthetic fiber made from wood pulp.

Although classified as synthetic fiber, it is actually a natural material.

Unlike cotton, artificial fiber removes materials that may sample or react to samples for transportation and processing during the production process, so it is usually used to sample for diagnostic tests.

Polyester fiber swab

"<yoastmark

Swab head material adopts polyester filament winding.

Polyester fiber is used for microbial collection, rapid diagnosis and PCR detection.

The polyester scraper has a higher release rate, but its cost is higher than cotton swab and rayon swab.

Foam tip swab:

Foam swab

Foam swab

The swab made of medical polyurethane is a very good diagnostic material, especially suitable for cell sampling.

The number of holes on the surface is generally 100 PPI (holes per inch).

This material has good hydrophilicity and poor absorption of hydrophobic substances.

Used in occasions where resistance to chemical corrosion is required, and it is also used for DNA and microbial sampling.

Synthetic swabs (rayon and polyester) are used to collect bacterial culture specimens, rather than cotton swabs that may contain inhibitory or toxic substances.

Flocked swab:

flocked swabs

flocked swabs

First developed flocking technology for cosmetics and industrial production.

Because of the planting process and the use of multi-head bifurcated polyester fiber materials.

The flocked swab has a very high absorption and release rate, and it is also effective for molecular sampling and absorption.

Some institutions designate to conduct research on nucleic acid sampling and certain genome analyses.

At present, the development of swabs not only reflects the changes in the materials of sampling swabs, but new demands in the fields of nursing, testing, and scientific research have led to the multi-dimensional development of swabs.

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.

About nylon flocked nasal swab

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.

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.

How to Choose a Correct Virus transport medium for COVID-19 Testing

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.

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!
