Viral Transport Medium Tube

Viral Transport Medium Tube

Viral Transport Medium Tube

A virus sampling tube is a product used to collect and transport infectious disease specimens. It is not a single product, but a set consisting of a sampling flocked swab, Viral Transport Medium and a plastic tube. Sampling process: use a swab to sample the patient, but the preservation solution into a plastic tube, put the sample into the plastic tube preservation solution, and transport the preserved sample to the laboratory for testing.

Special instructions for virus sampling tubes:

If the collected sample is used to detect viral nucleic acid, it must be used with a nucleic acid extraction kit and nucleic acid detection reagent; if it is used for virus isolation, it must be combined with a cell culture medium.

Different application fields have different requirements on the volume of sampling liquid, please replace the corresponding product according to the prompts in the sequence information:

Viral sampling tubes that collect viral samples from clinical patients generally require less fluid.

For a collection of single-use virus sampling tubes and short-term delivery of influenza virus from the external environment. We typically require a liquid volume of 3 to 6 ml.

Virus sampling tubes have three requirements, including transport, storage, and sample usefulness.

Transportation, ensure that the samples do not leak during transportation;

Preservation, ensure that the sample does not leak during the preservation process;

In terms of the usefulness of the sample, the sampling tube itself does not have a toxic effect on the sample, so as not to affect the material collected in the sampling tube, which in turn affects the test results.

COVID-19 Swab Test : Positive Covid Test

COVID-19 Swab Test : Positive Covid Test

Despite the recent surge in coronavirus cases, most Premier League clubs hope to continue playing during the holiday season. Due to the Covid-19 outbreak, only half of the game last weekend was left, and each round of new swab tests will continue to yield results of increasing cases.
This led several top coaches to question the safety of continuing.
Currently, all fans can still enter the stadium. However, there are reports that the UK may adopt secondary measures after Christmas. According to these regulations, only 2,000 spectators are allowed to watch the game.

Here is how to test for COVID-19 and what to do if the test result is positive.
 Stock up on healthy foods and anti-fever medicines, and avoid contact with others. Try to watch football matches at home.

COVID-19 testing methods.

COVID-19 infections have surged again, so you may find that you test positive.
With the highly contagious variant of Omicron circulating in many countries, reinfection is common, and people who are vaccinated may be susceptible to mild infections.
It is important to take precautions and be prepared to act if you are infected.

Here is how to do it:

How to confirm if you have COVID-19

As we all know, the symptoms of Covid-19 include “fever, fatigue, and dry cough”. Some patients will have symptoms such as nasal congestion and runny nose. Viruses are also a very large family. In the face of a turbulent epidemic, how doctors can quickly distinguish whether it is a “2019-nCoV” virus infection in the first place is obviously the key to fighting the epidemic.

What are the symptoms of COVID-19?

Some people infected with the virus have no symptoms. When the virus does cause symptoms, common symptoms include fever, body aches, dry cough, fatigue, chills, headache, sore throat, loss of appetite and loss of smell. In some people, COVID-19 can cause more serious symptoms, such as high fever, severe cough, and shortness of breath, which usually indicates pneumonia.
People with COVID-19 can also experience neurological symptoms, gastrointestinal (GI) symptoms, or both. These may or may not have respiratory symptoms.
For example, COVID-19 affects the brain function of some people. Specific neurological symptoms seen in people with COVID-19 include loss of smell, tastelessness, muscle weakness, tingling or numbness in the hands and feet, dizziness, confusion, delirium, seizures, and stroke.
In addition, some people have gastrointestinal (GI) symptoms such as loss of appetite, nausea, vomiting, diarrhea, abdominal pain, or discomfort related to COVID-19.
If you have been (or you suspect you may have been) exposed to COVID-19, You should also test whether you are experiencing symptoms.

How to test for COVID-19?

Special diagnostic tests must be performed to confirm that someone has an active coronavirus infection.

In most cases, the clinician will take a nasopharyngeal swab (or nose and throat swab).

Certain tests can be performed with saliva samples. Then check the genetic material of the virus in the sample (PCR test) or specific viral protein (antigen test).

Antibody testing can tell if someone has COVID-19. But an infected person does not immediately start to produce antibodies. It can take up to three weeks for a blood antibody test to become positive. This is why it is not useful as a diagnostic test for people with new symptoms.

How reliable is the test against COVID-19?

COVID-19 Swab Test: flocked swab test kits

COVID-19 Swab Test: flocked swab test kits

Currently, there are two types of diagnostic tests in the United States. The PCR test can detect viral RNA. Antigen tests (also called rapid diagnostic tests) detect specific proteins on the surface of the coronavirus. Antigen test results may recover within 15 to 45 minutes; you may need to wait a few days or longer to get PCR test results.

The accuracy of any diagnostic test depends on many factors, including whether the sample is collected correctly. For PCR tests that are usually analyzed in the laboratory, the test results may be affected by the conditions under which the test is shipped to the laboratory.

The test time will also affect the results. For example, if the test is performed on the day of infection, it is almost certain that the test result will be negative because there are not enough virus particles to detect in the nose or saliva. If the test is performed a few days after infection or a few days after the onset of symptoms, the chance of getting a false negative test result will decrease.

Generally speaking, if the test result is positive, it is almost certain that the person has been infected.

The negative test result is uncertain. The false negative rate of antigen testing is higher. If your antigen test result is negative, your doctor may order a PCR test to confirm the result.

Self-quarantine for 10 days

If you test positive for the virus, you should self-quarantine for 10 days.

CDC says this means don’t leave your home unless there is an emergency.
How soon after contracting the new coronavirus will I start the infection?
Emerging research shows that people are actually most likely to spread the virus to others within 48 hours of the onset of symptoms.

If you live with your family or roommates, keeping your distance is a challenge.
The ultimate goal is that you do not share the air with anyone else.

This means sleeping in a separate room with a separate bathroom, rather than in the same space, such as a kitchen or living room.

Ideally, have friends or family members leave food and drinks outside the door for you to collect.

What does self-quarantine or quarantine mean? What should I or shouldn’t I do?

It is important not to spread the infection to other people during the recovery process.

Although home isolation or home isolation sounds like a stay, you should be prepared for a long time during which you may feel disconnected from others and feel anxious about your own health and the health of your loved ones.

Staying in touch with others over the phone or online can help maintain social relationships, ask for help, and update others based on your situation.

Separate yourself from other people and animals in the house.

Stay in a specific room as much as possible and stay away from other people in your home. Use a separate bathroom (if available).
Wear a mask when you are sick.

Wear a mask when you are with others or pets, and before entering a doctor’s office or hospital.

Cover up coughing and sneezing.

When coughing or sneezing, cover your mouth and nose with a tissue, and then throw the used tissue into the lined trash can.

After sneezing, immediately wash your hands with soap and water for at least 20 seconds. If soap and water are not available, use an alcohol-based hand sanitizer with an alcohol content of at least 60% for cleaning.

Clean your hands often.

Wash your hands often with soap and water for at least 20 seconds, especially after blowing your nose, coughing or sneezing; going to the bathroom; before eating or preparing food.

If soap and water are not readily available, use an alcohol-based hand sanitizer with an alcohol content of at least 60% to cover all surfaces of your hands and rub them together until it feels dry.

Avoid touching your eyes, nose and mouth with unwashed hands.

Don’t share personal household items

Do not share dishes, drinking glasses, cups, eating utensils, towels or bedding with others or pets at home.

Monitor symptoms

Check your temperature twice a day to monitor if you have a fever and stay alert for coughing or breathing difficulties.

If you are asymptomatic and start to have a fever or fever, cough or difficulty breathing, immediately limit contact with others (if you have not already done so).

Call your doctor or local health department to determine if you need a medical evaluation.

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.

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

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.

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.

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.

Winter is coming, the cold current is coming, the goose feather like snow is flying all over the sky, and the whole world is wearing a white coat.

Many customers once again throw this “soul question” to us. “Can your Viral Transport Kits adapt to the cold environment?”

He answer is yes. Let’s follow Cell medical Dr. Li for experimental verification!

Experimental purpose

Verify that the Viral Transport Medium of cell medical (Dongguan) Co., Ltd. has no significant impact on its service performance after low-temperature freezing and thawing.

Experimental scheme

Simulate the process of low-temperature freezing during transportation, place the sampling tube in a low-temperature environment for 24 hours, and then melt at room temperature. The sampling tube products stored normally without freezing and thawing were used as the control. Each group was added with virus mixture, stored at 4 ℃ for 24 hours, and then bathed in water at 56 ℃ for 30 minutes for nucleic acid extraction and nucleic acid detection. Set 2 repetitions for each group.

1. Low temperature icing simulation: set two low temperature gradients and place the sampling tube in two low temperature environments of – 20 ℃ and – 80 ℃ respectively.

2. Mixing of virus solution: We used two different concentrations of virus solutions, representing high and low concentration gradients respectively. The copy numbers of virus solution were 106 copies / ml and 104 copies / ml, respectively. Simulate the actual sampling process, add the virus solution in the volume ratio of 1:10 to the sampling solution, and the virus solution is 100 μ 50. 1ml of sampling solution and add 100 ml to it μ L of oral liquid.

3. After mixing each group, place it in 4 ℃ environment for 24 hours and inactivate it in 56 ℃ water bath for 30 minutes.

4. Extract the nucleic acid of each group of virus, and detect the virus content of each group by RT qPCR. The CT value is used as the basis for result evaluation. The higher the CT value, the higher the detected concentration.

5. The experimental groups are as follows:

Main experimental materials

  •   Sampling solution: virus preservation solution produced by cell medical (Dongguan) Co., Ltd.
  •  virus diluent: the virus isolation serum-free medium of Cell medical was used for gradient dilution.
  •   virus for verification: porcine epidemic diarrhea virus. Its structure and genome size are similar to those of New Coronavirus.
  •   nucleic acid extraction reagent: non cleavage nucleic acid extraction reagent (magnetic bead method).
