Innovative jet embedded nylon modern technology can improve the effectiveness of the example collection from the client to the largest degree. The nylon has stuck vertically and uniformly to the surface of the swab pointer, which can boost the effectiveness of accumulating as well as releasing cells as well as liquid samples. Improve analytical level of sensitivity, No sampling recurring, and can speed up the specimen therapy. PS sticker label is very easy to break short. Adjusted to cervix wombs, nasopharynx, oral cavity, Forensic Purchase System as well as DNA accumulating, etc. Private stuffed.

Features

1. Flocked swabs provide the best sampling effect. Groups of swabs are the best choice for rapid diagnostic testing because they can better collect cells or organisms at the collection point and quickly release intact cells.

2. Enhance the sensitivity of diagnosis. The patented flocking technology turns each strand of fibre into a velvet brush, resulting in hundreds of thousands of contact points, which can better collect and release samples. The increase in the number of target cells (compared with non-flocking swabs) helps to improve the sensitivity of rapid diagnostic tests.

3. The flocking swab with rapid elution of CellMedical is closely combined with the handle and does not contain the internal fabric or other inner cores that absorb the samples, which can collect and retain more samples. This can not only provide a better sample size but also make the sample released into the liquid medium more quickly and completely.

4. Proprietary long flocking fibre flocking swab the proprietary long flocking fibre forms a network structure, which can collect and retain more specimens than traditional cotton, polyester or man-made fibre swabs. The inner core of an ordinary cotton swab will easily lock the sample, making it difficult to elute and pour it into the medium.

5. Convenient handling and transportation. Most oral, oropharyngeal and nasopharyngeal flocking swabs have prefabricated breaking points, so you can easily break the handle before putting the swab into the vial. Sterile flocking cotton swabs will also be equipped with dry transport tubes and media filling transport tubes and other transport materials. After sampling, the storage and transportation can be completed conveniently.

In a word, a flocked swab can better meet the sample collection needs of laboratories, hospitals and other institutions. It is the preferred tool for sample collection and elution.

Combined Throat And Nose Swab

Posted on 2022年5月10日2022年5月10日 by Dr. Lee

What is the difference between a nasal (Nose) swab and a throat swab for nucleic acid testing

The sampling method and location are different. The accuracy rates of the nucleic acid test ( PCR Test ) nasal swabs and throat swabs are usually similar, and the main difference lies in the sampling method and sampling site. For nasal swabs, nasopharyngeal swabs (flocking swabs) are mainly used to test the secretions from the inside of the nasal cavity and the surface of the nasal mucosa through the nasal cavity;

Throat swabs: Health care workers collect samples in the mouth with oropharyngeal swabs. Health care workers take throat samples for testing to determine whether a patient has the new coronavirus.

Are both throat swabs and nasal(Nose) swabs required?

Let’s talk about throat swabs first.
The “oral sampling” and “nasal sampling” mentioned above are actually test methods in which medical staff use medical swabs to collect samples from the pharynx in nucleic acid testing (PCR).

COVID-19: Will The Pandemic End in 2022?

It is very important to continue swab testing while the pandemic is still ongoing

Whether entering from the nasal cavity or the mouth, the specimens we need to collect are pharyngeal secretions, including sputum. Compared with the oral route, nasal sampling can provide better safety protection for the sampling person. Because oral sampling requires subjects to open their mouths wide, this increases the risk of virus transmission by droplets. However, if it is collected through the nasal cavity, the environment is relatively stable, and the medical staff who operate it will be safer.

What is the difference between a throat swab and a nasopharyngeal swab, which is more accurate?

The main difference between nasal swabs and throat swabs lies in the location and material of the specimens, which are usually as accurate. The throat swab is in the pharynx, and the nasal swab needs to go into the nasal cavity, not the external nasal cavity. It needs to use a longer swab and slowly rotate it to the deep part of the nasal cavity, so the parts of the material are different. Nasal swabs are special, and the material is relatively soft, which is convenient for reaching the deep nasal cavity through the nasal cavity. The process of taking it may take longer than that of throat swabs.

Compared with nasopharyngeal swabs, oropharyngeal swab sampling is sometimes difficult to meet the normative sampling requirements due to irritating reactions, and the actions of eating, drinking and swallowing will reduce the oropharyngeal to a certain extent. The virus enrichment of 2000 may affect the positive detection rate of oropharyngeal swabs.

Which is better, nasal(Nose) swab or throat swab?

No matter which one is adopted, the key lies in the depth of the collection, whether the collection is in place and the length of contact time with the deep mucosa.

From the personal experience of the testing population, throat swabs will be less irritating and uncomfortable than nasal swabs.

Sterile Flocked Swab

Oropharyngeal swab

　　• The operation is relatively simple and less irritating, suitable for large-scale screening.

　　• The sampling staff will guide the subject to open the mouth, and then use a sterile long cotton swab to gently scrape the subject’s throat to collect secretions from both palatine arches, pharynx, and tonsils.

Nasopharyngeal swab

　　• The technical requirements are high, the human body does not feel very comfortable, and the accuracy is higher than that of oropharyngeal swabs. For key groups such as isolation points.

　　• The sampling staff will insert a long sterile cotton swab into the nostril of the subject, and reach the mucous membrane deep in the nasopharyngeal cavity, stay for a few seconds to soak the secretion, and then take it out.

Who is not suitable for nasal swab

What is A Covid-19 NP Swab?

When collecting nasal swab specimens, the flocked swab ( learn more ) will enter the nasal cavity.

f the medical staff operates in a standardized manner, it will reduce the irritation to the mucous membranes.

But because we can’t see the sampling position of the pharynx.

It mainly relies on the hands of medical staff to feel the resistance, so the technical requirements of the operator are very high, and the tools used are also more complicated.
The improper operation will cause certain irritation to the nasal mucosa, so it is not recommended for patients with sinusitis and allergic rhinitis to do nasal swabs to avoid damage to the nasal cavity.

How to overcome the discomfort of throat swab

When collecting throat swab specimens, the oropharyngeal flocked swab will cause certain irritation to the pharynx. For some people with the sensitive pharynx, nausea and vomiting may occur.

Recommended to relax before collecting specimens.

Don’t get too nervous. If you feel discomfort in your throat after collection, you need to eat less spicy, irritating and greasy food, drink more water, eat more vegetables and fruits, and arrange rest appropriately. Generally speaking, it does not take long to return to normal.

Experts said that the study found that the nucleic acid-positive duration of feces or anal swabs of some infected people is longer than that of the upper respiratory tract. Increasing anal swab sampling can improve the detection rate and reduce missed diagnosis; but anal swab sampling is not convenient enough, and currently only for isolation. Points and other key groups to use.

Flocked Sterile Swabs

Posted on 2022年4月23日2022年4月23日 by Dr. Lee

Disposable sampling swabs, We believe you are familiar with them in the past two years because most of the testing tools used for nucleic acid testing (PCR tests) are disposable sampling swabs.

Usually, we see most nasal swabs and throat swabs, and the sampling swabs we commonly use are flocking swabs.

The flocking swab is a disposable sampling swab composed of a nylon short fibre fluff head and abs plastic rod.

Recently, there have been many concerns about rapid antigen detection on the Internet.

One of them is that if the “single-use sample collection swab” (sampling flocked swab) used in the antigen test is “non-sterile” and “non-sterile”. Bacteria” products. There are risks when using it.

Citizens disinfect the sampling swab with alcohol before conducting antigen testing at home? ( Alcohol disinfection is not advisable)

Experts and industry insiders say such concerns are unnecessary as long as qualified products are available through formal channels.

Discard damaged or contaminated swabs.

Specimen collection sterile flocked swab

Are there risks to using “non-sterile” “non-sterile” Specimen collection swabs?

There are two main issues that netizens worry about:

One is to worry about the “bacteria” of the sampling swab, which will affect the results of the antigen test, such as “false positives”;

The second is to worry about the “bacteria” of the sampling swab. During the sampling process, “bacteria” will enter the human body with the sampling swab and affect health.

Nasopharyngeal swab test

Regarding the effect of “bacteria” sampling swabs on antigen test results, experts said that this is a misunderstanding caused by confusing bacteria and viruses.

You know, the antigen test “looks” for the antibodies produced by people infected with the new coronavirus.

The display window of the reagent strip contains a protein that recognizes the antibody, like a dam, blocking the colloidal gold that binds the antibody to the virus. So it appears red in the display window.

Therefore, even if the sampling swab contains “bacteria”, the kit will “ignore” it and focus on “finding” the antibodies produced by the new coronavirus infected person.

Since the kit is not interfered with by “bacteria”, it will not affect the results of antigen detection.

For some people who think that “bacteria” sampling swabs will affect human health, experts say that this may be due to a lack of understanding of “sterile” products.

Sterile

The single-use Specimen collection swab can currently be applied for registration as a second-class medical device, and can also be registered as a first-class medical device (the third-class is the highest level) in the regulatory department.

If it is a Class II medical device, it must meet the sterility requirements when it leaves the factory. While a Class I medical device has no relevant requirements and can be listed in the state of “non-sterile” and “unsterilized”.

Experts said that “sterility” refers to the state of no viable microorganisms. All medical devices must meet certain hygienic requirements, such as strict control of the number of microorganisms before they can be qualified for the market.

Flocked Sterile Swabs

Flocked swabs are mainly used for oral and nasopharyngeal sampling, cervicovaginal sampling, and laboratory testing.

Sterile Flocked Nasopharyngeal Swab is a 100% nylon flocked swab that provides exceptional absorption quality with a flexible handle engineered to reach remote areas of the nasopharynx for specimen collection.

According to different uses, it can also include nasopharyngeal swabs, throat swabs, oral swabs, DNA swabs, and cervical swabs.

It is similar to the above classification, but it is slightly different.

For laboratory testing centres and hospitals.

flocked swab — CellMedical

What are the advantages of flocked Sterile swabs?

Using nylon fibre flocking technology. The front end of the swab has nylon staple fibres fixed vertically. By making the entire collection area of the swab free of absorbent holes. The sample does not scatter and become trapped in the fibres, facilitating faster and more efficient elution.

This makes flocked swabs ideal for PCR work, as flocked swabs are biocompatible and ideal for PCR work.

Reuse Nasopharyngeal Swabs Disadvantage

Nasal swabs reused at an Indonesian airport? What are the dangers of reusing nasal swabs?

Since the epidemic, the term nasal swab testing has entered our lives. Basically, you will be asked to do a nucleic acid test when you are on a business trip or travelling. After the test is completed, the sterile flocked swab will be processed for medical waste. However, news broke out recently that refreshed the three views, and netizens called out “there is no bottom line”!

According to reports, employees of a medical company in Indonesia were found to be repeatedly using sterile nasal swabs when testing airport passengers. At present, more than 9,000 passengers are expected to be affected.

After investigation, the Indonesian police found that the employees involved first performed Nasopharyngeal Swabs tests on passengers with sterile nasal swabs every day, then cleaned the used sterile swabs with alcohol, and then packaged them for use by the next batch of passengers. . This behaviour is outrageous.

What are the dangers of reusing nasopharyngeal swabs?

The nose is a barometer of human health. When there are lesions in the body, the colour of the snot changes to yellow or green. Nasopharyngeal swabs are a test sampling method to assess the presence of respiratory viral or bacterial infections by collecting samples from the surface of the respiratory mucosa.

As a rule, nasal swabs cannot be reused. If the nasal swab is reused, the consequences will be disastrous.

If the nasal swab is reused, it will increase the risk of virus infection. Previously, a British research team found that two kinds of cells in the nose may be the other infection sites of the new coronavirus. A clinical study found that the viral load of nasal flocked swabs The amount is significantly higher than that of throat swabs. If nasal swabs are reused, it is likely to cause cross-infection and expand the scope of infection.

On the other hand, it may lead to inaccurate test results, false positives or false negatives. It may cause psychological panic and unnecessary treatment to the subjects, and false negatives may mean that the subjects cannot find out that they have been infected in time, miss the best treatment time, and even cause more people to be infected.

Nasopharyngeal flocked swab CellMedical

Why are the sample collection swabs for nucleic acid testing all put together?

This kind of multi-person mixed inspection can improve efficiency and reduce costs.

Mixed sampling testing refers to mixing samples from multiple people (generally no more than 10 people) into the same test tube for testing, improving testing efficiency and reducing testing costs, but the waiting time for centralized sampling may be slightly longer. According to the voluntary principle, the nucleic acid test of all employees can be tested by mixed sampling technology. The laboratory testing time for mixed sample and single-tube testing is the same, which does not affect the time for issuing the testing report.

The so-called five-in-one and ten-in-one mixed sampling detection technology are to put 5 or 10 individual swabs into a collection tube. When the test result is negative, the mixed sample is negative, and the mixed sample is 5 people. or 10 people are safe;

If there is a positive result, the relevant department will be immediately notified to temporarily isolate the 5 or 10 subjects in the mixed tube, take a single tube swab again for the review, and then determine which of the 5 or 10 people is positive.

What should I pay attention to when doing a nucleic acid test (PCR test)?

Pcr test nasal swab and an antigen test difference for covid 19

Today, many people who travel to and from high-risk areas of the epidemic require nucleic acid testing.

So, what should we pay attention to when doing nucleic acid testing (PCR SWAB TEST)?

Before the nucleic acid test: do not eat within 2 hours, do not smoke or drink within 30 minutes, carry a valid ID card, wear a mask correctly, and inform the testing personnel of past medical history or related matters.

When doing nucleic acid testing: Keep a distance of more than 1 meter when queuing, tilt your head slightly, relax, take a deep breath, and have symptoms such as dry cough or sneezing, use a tissue or cover with your arm.

After the nucleic acid test: leave the collection site immediately, and wipe your hands with hand sanitiser or alcohol.

In fact, whether it is a nasopharyngeal swab or a throat swab, it is an effective virus detection method. Although there will be slight discomfort during the test, it will soon return to normal and will not affect your health. Therefore, if necessary, we must actively cooperate with nucleic acid testing, which is responsible for ourselves and others.

Nucleic acid detection: For virus detection method.

It uses a collection flocked swab to collect a sample from the throat or nose of the tester and then conducts the test to obtain the final result.

Some people found that the flocked swabs for nucleic acid testing will be placed in a bottle(VTM Tube).

This is a mixed test, and most of them occur during nucleic acid testing of all staff, which will not affect the detection effect.

Will the swabs for nucleic acid testing be reused?

Prohibition reused.

In addition to sampling, reagents and other factors, the subject’s own reasons may also lead to “false negatives”.

Not to eat for two hours before the nucleic acid test, not to drink water for the first 30 minutes. And not to smoke, drink water or chew gum to reduce behaviours that may interfere with the test results.

There are other influencing factors before sampling and testing,

1. Please do not take antibiotics a few days before the nasal swab.

2. Do not use disinfectant mouthwash or smear on the affected area a few hours before the nasal swab.

3. Do not eat, smoke, or drink for a few hours before the nasal swab.

What is a virus sampling swab kit?

Covid VTM Swab Test

The virus sampling swab set is a virus sampling and transfer product for virus nucleic acid detection.

It generally consists of a sampling swab, a sampling tube and a virus preservation solution.

For the nasopharyngeal and oropharyngeal new coronavirus sampling swab sets.

Also known as virus transport medium (Viral Transport Medium), referred to as VTM.

According to the composition and function of virus preservation solution, it includes non-inactivated and inactivated types.

The purpose of the single-use virus sampling tube:

Viral Transport Medium With Swab

The single-use virus transport medium with tube is our company’s best-selling star product. It is suitable for the collection and transfer storage of various influenza viruses, clinical new coronaviruses, influenza, measles and other virus samples. nucleic acid extraction and later virus isolation.

It is also suitable for collecting and transporting specimens such as Chlamydia, Mycoplasma, and Ureaplasma urealyticum.

Specimens are usually collected from the oral cavity, throat, nasopharynx, anus, and other human body parts.

Combination features of our single-use virus sampling tube kits (vtm swab kits):

Disposable virus sampling tubes include sampling swabs and sampling tubes (vtm kits).

Test Sample Collection Vtm Kit

1. Sampling flocking swab: our company uses a nylon flocking swab (vtm swab). Because nylon flocking has no toxic effect on microorganisms and viruses and does not contain RNase and DNase.

It can maximize the collection and release of virus samples and ensure the accuracy of PCR test results.

The flocked swab rod: ABS material, with a unique breakpoint design.

Convenient to put into the sampling tube without contamination.

2. Virus sampling tube: The tube body and tube cover are made of polypropylene, which will not deform at high temperature and high pressure (121°C, 15min). And will not become brittle at low temperatures (-196°C).

Resistant to static extrusion and dynamic impact.

The bottom cone design is resistant to centrifugation and shock.

They are packed with a transport medium (inactivated type, preserved type) for the release and preservation of samples to prevent leakage.

The sampling tube has built-in magnetic beads, which are convenient for elution and facilitate the release of more viruses into the virus transport medium.

Before the higher positive rate of PCR detection, the storage solution in the virus sampling tube was Hank’s solution.

Now, the virus sampling tube preservation solution has been upgraded to CellMedical virus preservation solution.

(that is, UTM, recommended by the World Health Organization and the National Influenza Center of China.)

Based on hank’s solution, BSA, HEPES, amino acids, glycerin and other ingredients. A high PCR test is positive.

Virus preservation solution includes non-inactivated virus transport medium and inactivated virus

In the non-inactivated COVID-19 sampling swab set, the components of the virus preservation solution usually include nutrients (such as salts, proteins, glucose), bacteriostatic agents, buffers, phenol red indicator, etc. required for the survival of the virus.

This virus preservation solution can maintain the activity of the virus to the greatest extent.

Not only for virus detection but also for virus culture and isolation.

In the inactivated new coronavirus sampling swab kit, the components of the virus preservation solution usually include buffers, virus lysing agents (usually guanidines), surfactants, etc.

This preservation solution can directly lyse the virus to release nucleic acid, which is convenient for subsequent nucleic acid detection.

Covid-19: Antigen Test Self-Test Swabs Must Be Sterilized?

Posted on 2022年4月15日2022年4月15日 by Dr. Lee

Covid-19 antigen test self-test swabs must be sterilized?

New crown antigen test self-test sampling swabs must be sterilized? Alcohol disinfection is required before “non-sterile sterilization”?

Yesterday, a colleague looked at the record, it was about the swab used for the self-testing agent for the covid-19 antigen.

One user found that the swabs were non-sterile flocked swab during use, while some communities received sterilized cotton swabs.

Therefore, it is recommended to sterilize the flocked swab with 75% alcohol before using it.

Experts and industry insiders say such concerns are unnecessary as long as qualified products from formal channels are used.

If citizens receive swabs that are suspected to be damaged or contaminated, please discard them directly according to relevant requirements.

Is it risky to use “non-sterile” and “unsterilized” sampling swabs?

Sterile flocked swabs specimen collection

Specifically, there are two main problems that netizens worry about:

First, they are worried that the sampling swabs will be “bacteria”, which will affect the results of antigen testing.

Such as “false positives” And so on;

The second is to worry about the “bacteria” of the sampling flocked swab.

During the sampling process, the “bacteria” will be brought into the human body, affecting health.

75% alcohol can indeed disinfect cotton swabs, but a flocked swab with 75% alcohol may denature the scraped viral proteins!

The antigen is no longer that antigen, so it may lead to missed detection!

You must know that the antigen test “looks” for the antibodies produced by the new coronavirus infected person.

The display window of the reagent strip contains a protein that can recognize the antibody, like a dam, which intercepts the colloidal gold combined with the virus antibody, which is displayed in the display window. is red.

Therefore, even if the sampling swab contains “bacteria”, the kit will “ignore” it and focus on “finding” the antibodies produced by the new coronavirus infected person.

Since the kit is not interfered with by “bacteria”, it will not affect the results of antigen detection.

For some people who think that “bacteria” sampling swabs will affect human health, experts say that this may be due to a lack of understanding of “sterile” products.

Sterile ones are the best.

Ethylene Oxide Covid Test Sterile Swab

Flocked Nasopharyngeal Swab Suppliers and Manufacturers

However, the use of sterile flocked swabs is not mandatory, and the use of non-sterile ones will not affect the detection effect.

For the EU CE self-test, it must be equipped with a sterile CE certified swab.

Non-sterile flocked swabs also have requirements for the number of colonies.

Non-sterile swabs are also sold in the EU (probably for professional use).

A group of friends also said: “I would rather not sterilize it. As it is now, if the epoxy desorption time is not enough, it will be sold. It is better not to sterilize it. Anyway, the oral and nasopharynx is not a sterile environment, so what are you afraid of?”

The expert replied: “Swabs are generally sterilized by irradiation, and less sterilized by ethylene oxide (EO). Even if sterilized by EO, they are packaged in dialysis paper. The general standard for ethylene oxide analysis is 14 days. If the heat is accelerated, it will usually be out in 3 days. Counting the storage and logistics time.

It is basically enough for 14 days, and it is safe for the testers.”

In summary:

The European self-test product is equipped with a sterilized swab, which seems to be a product below the European standard.

At the same time, non-sterile swabs can also be used, but they must meet quality inspection standards, such as colony count.

Finally, remind everyone, do not to use alcohol to disinfect swabs, which may cause missed inspections! Of course, the outer package of the reagent can be sterilized if it is conditional!

Covid Swab Test To Your Baby

Posted on 2022年4月11日2022年4月12日 by Dr. Lee

How To Properly Administer A Covid Swab Test To Your Baby

COVID-19 still plagues all parts of the world, and it will become more serious in spring, so there are still many people who need to do nucleic acid tests.

Do many parents have many questions about nucleic acid testing for children, especially babies, such as how to do nucleic acid testing for 10-month-old babies?

A little girl is being swab tested for nucleic acid

How do nucleic acid swabs test for children?

The nucleic acid test method for 10-month-old infants and adults is the same.

The method of throat swab is used. The throat is sampled.

When sampling, you only need to tilt your head slightly, open your mouth wide, and wait for the medical staff to use a flocked swab.

The swab stick can be sampled.

You may feel a little nauseous during sampling, but it is not particularly uncomfortable in general.

This kind of discomfort is acceptable to basic children, and the sampling process is relatively fast, so parents don’t need to worry too much.

Of course, it is not ruled out that some children do not cooperate. In this case, older children can communicate well, explain the situation, and parents can show the children how to carry out nucleic acid testing; if it is a child who is too young to communicate, then you have to grab it forcibly for sampling.

It should be noted that before going to the hospital for examination, you must make an appointment first, otherwise, it will be a waste of time.

Since different hospitals or testing centres generally have different methods for ordering nucleic acid testing.

It is important to understand the hospital nucleic acid testing process before officially performing nucleic acid testing.

In addition, it is not recommended to eat about two hours before the nucleic acid test.

If you are nauseous during the sampling, you may vomit or spit milk, but this is rare.

Baby swab tests

You bring your child’s safety to a stable place (a blanket on the floor, a changing table, another adult’s arms).
Consider wrapping them in a warm blanket to relax and prevent their elbows from helping you.
Show them a pacifier (make sure you can adjust their nostrils) if the pacifier will soothe them.

In general, bring the kids to a convenient place where you know them best.

As an adult helper, you can take the kids on their laps.

We recommend keeping your back against the patient’s reason and facing toward the person holding the flocked swab.

Then you can start!

The nucleic acid test method for children is the same as that for adults.

The throat swab is to extract the secretions of the respiratory tract for testing.

Because the baby has a problem with cooperation, it is best not to feed the child 2 hours before the nucleic acid test.

During the nucleic acid detection process, children may not cooperate.

If they have just finished eating food, they will vomit, which will affect the nucleic acid detection results.

Nucleic acid testing uses a long throat swab to smear on the back wall of the pharynx.

The medical staff are more skilled and will not cause much impact on the child.

Instructions for use, specimen collection

Note Sterile gloves, protective clothing and goggles should be worn when collecting and handling microbial specimens;

Open the peel bag and remove the flocked swab.

CellMedical Specimen Collection Swabs manufacturers

Determine the age of the child, the button clips are on the appropriate upper lube), make sure the swab is not too deep;
To collect samples, the observer (observer) should only be at the necessary distance.

Viral transport media for COVID-19 testing

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

At present, medical technology needs to promote positive energy!

The current epidemic has come and gone.

In particular, important medical materials such as disposable virus sampling tubes (virus transport media) play a key role.

At present, the quality of the products of various manufacturers on the market is also uneven, and there is also a risk of affecting the accuracy of the experimental results.

Make products with a realistic and rigorous scientific attitude;

Let the front-line medical staff have no worries, and provide them with a steady stream of “cannonballs”.

Below we will define the virus delivery medium and explain typical components and options for use.

What is a virus transport medium?

10ml Viral Transport Medium VTM Swab Tube Kit

It is suitable for the collection of various influenza viruses, avian influenza viruses, COVID-19 novel coronavirus, hand, foot and mouth virus samples.

Realize the lysis and inactivation of the virus in the sample.

At the same time effectively ensure the stability of the viral nucleic acid in the sample during storage and transportation at room temperature.

And collect the sample for subsequent PCR analysis and detection.

Features:

✳ Room temperature stable storage;

After use, Stored at room temperature for 7 days, which is conducive to the collection and transportation of samples.

✳ Quick release

Using swabs to collect samples is conducive to subsequent nucleic acid release.

✳ Safe and rapid inactivation of virus samples

The preservation solution can quickly inactivate virus samples, effectively reducing the level of biosafety requirements for sample transportation and subsequent testing laboratories.

✳ Swab breakpoint design

After sampling, the designed rod breakpoint design can easily break the head and save it in the tube.

What are the components of the viral transport medium?

The sample transport medium, viral transport medium (VTM), stabilizes cells and viruses in potentially infected patient samples during transport from the point of collection to the testing facility.

These reagents are suitable for various types of viruses, including coronaviruses, herpes viruses, and influenza viruses.

CellMedical’s products for sample transport include viral transport media and saline solutions, which are both efficient collection and transport media for subsequent qPCR assays.

All sample transfer media are manufactured in a state-of-the-art GMP facility certified to ISO 13485:2016.

UTM Tube with NP Flocked Flexible Swab

1. Virus sampling tube;

Some data suggest that polypropylene (Polypropylene) is related to the adsorption of nucleic acids, especially at high tension ion concentration, polyethylene plastic (Polyethylene) is easier than polypropylene (Polypropylene) to grasp DNA/ RNA.

In addition, when using breakable swabs, the storage tube should try to choose a container with a height of more than 8 cm to prevent the contents from splashing.

Some tubes may be formulated to contain buffered proteins and antibiotics to inhibit the growth of potentially contaminating bacteria and fungi.

2. Virus Transport Media;

VTM consists of Hanks Balanced Salt, Foetal Bovine Product, anti-bacterial prescription antibiotics, anti-fungal anti-biotics as well as Phenol Red as an indication for real-time surveillance of pH security of the service.

3. Collection of flocked swab;

The sampling swab directly contacts the sampling site, and the material of the sampling head is closely related to the subsequent detection.

Sampling swab tips should be made of Polyester (PE) synthetic fibers or Rayon (man-made fibers).

Prohibit calcium alginate sponges or wooden stick swabs (including bamboo sticks).

For example, the material of the swab tip cannot be cotton.

Products, because cotton fibers have strong adsorption of protein.

It is not easy to be eluted into the subsequent preservation solution.

Our flocked swabs are famous for their stable and reliable performance and excellent absorption and elution ability.

Viral transport media applications

The virus sampling tube is a complete set of centrifuge tubes for sampling and transporting viruses such as influenza virus, hand, foot and mouth virus, covid test, etc. in the microbial sampling transport tube, also known as the specimen transport tube.

In the current epidemic, virus sampling is also an important part. Generally, viruses exist in large quantities in the nasopharynx of the human body.

The pharyngeal tester collects virus samples from the nasopharynx and puts them in a virus sampling tube.
