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

Posted on 2021年11月25日2022年3月22日 by Dr. Lee

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

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.

Hot sale product Cell Flocked Swabs

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.

Hot sale product Cell Flocked Swab

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.

Flocked Swabs for Sample Collection

Posted on 2021年11月20日2022年3月22日 by Dr. Lee

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

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.

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.

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.

“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.”

Quick covid test |How does covid testing work?

Posted on 2021年11月10日2021年11月10日 by Dr. Lee

A new covid test at home has been authorized by the U.S. Food and Drug Administration (FDA) for emergency use (EUA).

Here’s what you need to know about testing at home.

How can I get quick covid test?

Cell medical’s covid test at home now has a prescription, which means Americans can get one from their health care provider.

If doctors suspect that their patient is infected with covid – 19 within the first six days of symptom onset, they can prescribe a rapid test.

E-mail：flockedswabs@gmail.com

How does testing work?

Rapid Antigen Test is a lateral flow test, a portable covid test that usually returns results faster than the widely used laboratory based PCR test.

It works by detecting nasal swab samples and provides positive or negative results within 10 minutes. The results appear on test strips exposed to nasal swab samples.

The FDA said flocked swab can be collected from people aged 8 and over, but if the tested children are less than 14 years old, it should be collected by adults.

How accurate is the test?

Cell medical claimed that the time when the positive results of the test matched the PCR test was 84.8%, and the negative results matched the PCR test were 99.1%.

FDA said that the negative test results of covid test do not necessarily exclude the possibility of covid – 19 infection.

“and should not be used as the only basis for treatment or patient management decisions, including infection control decisions.

“People who are negative and continue to experience COVID 19, have a fever, cough and / or shortness of breath, may still have SARS – CoV – 2 infection. Follow up care should be sought from doctors or medical staff. ”

Not all side flow tests require the use of prescriptions. On December 15, the FDA issued the EUA for the first outside counter flow covid test at home.

The covid – 19 family test also uses nasal swab samples to detect covid infection and works with people aged 2 years and older.

The FDA said that in the population with covid symptoms, the ellume test correctly identified 96% of positive samples and 100% of negative samples. In the population without symptoms, it collected 91% of positive samples and 96% of negative samples.

Similarly, the FDA said that the negative results of the test do not necessarily exclude the possibility of covid infection.

Broader prospects

According to CDC data, as of Monday, the United States had reported 47.5million cases of covid and 778,316 deaths.

The data also showed that 432 million people were vaccinated on Monday.

Our company uses the existing technology “spraying technology” to vertically attach millions of nylon flocked micro fibers to the head of medical grade handle through the flocking process of electrostatic charge. The function of vertical nylon fiber is similar to that of soft brush. Using this soft brush in the sampling process makes the user feel no foreign matter. 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, nasal swab, its upper end of the rod is thinner and softer, and its breaking point is longer.

2. Flocking swab samples release more.

The capillary action between nylon fiber bundles promotes the strong hydraulic absorption of liquid samples. The sample remains on the surface to make elution easier. In the traditional cotton swab, most of the samples collected are still captured in the fiber matrix of the head, which is not easy to release or the release amount is small. Flocked swabs have been shown to release up to 95% of the sample, compared with 25% for standard fiber pointed swabs. If the sample size is particularly small, the use of flocking swabs is particularly important.

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, disposable sampling swab is made of better quality nylon flocking swab.

This makes flocking swabs an ideal choice for PCR Swab Test. Therefore, for scientists using PCR technology, the new flocking swab is PCR compatible and does not contain RNase and DNase.

What elements should a good sampling swab meet？

2021-11-04

In the collection of virus samples, small sampling swabs are always ignored, and people often ignore the judgment of its quality. However, the sampling swab is the “vanguard” in the whole nucleic acid detection process. It is the first area to contact the virus. It can be said that it controls the “lifeblood” of the whole nucleic acid detection process.

sampling swab-flocked swab

Cell medical (Dongguan) believes that a good sampling swab should have three elements——

1: more samples. That is, the virus samples collected by the sampling swab should be as many as possible.

2: release more. That is, the virus samples collected by the sampling swab should be released into the sampling solution as much as possible.

3: excellent design. That is, the design of sampling swab shall not interfere with the nucleic acid detection in the last link.

It is well known that after large-scale nucleic acid screening, the previously commonly used winding swabs were eliminated, and flocking swabs that are easier to collect release samples were used.

However, it is not enough to unify the material.

The design of flocking swab is also very exquisite in structure.

Different nylon fiber arrangement and density determine the difference of sample collection and release.

A good swab can avoid missing inspection to a greater extent.

Flocked Tip Swab

What are the advantages of flocking as a sampling swab?

advantages of flocking as a sampling swab

When it comes to sexual sampling swabs, I believe you don’t feel strange at this time.

Because most of the detection tools used for nucleic acid detection are disposable sampling swabs.

Sampling swabs directly contact our human organs, such as nasal swabs and pharyngeal swabs for nucleic acid detection.

So the material selection of sampling head is very important, and the material of sampling head is closely related to subsequent detection. The sampling swab shall ensure the sampling amount and release amount, and the selected material shall not have substances that affect the subsequent detection.

Advantages of flocked swab

Flocked Tip Swab,Cell medical (Dongguan) Co. ,Ltd.

·Compared with the traditional winding swab, the amount of samples collected and released by flocked swab is three times higher, and it will not cause harm to human body.

·The sampling time of flocking swab is 3-5 seconds, which is fast and convenient to improve work efficiency.

Only by extracting samples faster can we complete the collection and analysis more efficiently.

·Moreover, through the directional friction effect of the brush fiber layer,effective collection of samples.

Therefore, the flocking swab is particularly conducive to the collection of trace DNA.

·A large number of clinical experiments show that compared with ordinary sterile cotton swabs, flocking swabs have a better effect on the collection and transportation of clinical microbial samples. This is especially true for those specimens that cannot be submitted for examination in time and placed for too long.
