PCR Swab Test detection disposable virus sampling tube inactivated non-inactivated production supplier

Viral Transport Medium Tube:  virus transport tube, which consists of a virus storage tube and virus storage solution.

Virus transport tube: specially designed in combination with subsequent PCR instruments for the rapid detection of viral diseases.

 The virus preservation solution ( Viral Transport Medium) is a protective liquid medium added to the virus sampling tube to protect the samples after nasopharyngeal swab sampling.

Includes inactivated viral transport media and non-inactivated viral transport media.

Usually, during nucleic acid detection, nucleic acid PCR cannot be performed directly at the sample collection site.

If the samples collected by flocked swabs need to be transferred for inspection, VTM needs to be added.

Virus detection is different from conventional biochemical detection.

The virus itself is a simple-structured microorganism that must be parasitic in living cells.

After sampling, the virus leaves the host cell. Its protein shell and nucleic acid are quickly degraded in the sampling tube.

So it is impossible to determine whether the initially collected sample contains the virus during nucleic acid detection, which may easily lead to false negatives.

　　The non-inactivated virus preservation solution contains a variety of solution components that are beneficial to the cultivation of virus cells. Which can ensure the integrity of the virus and help increase the survival time and stability of the virus.

　　A virus is a non-cellular life form that consists of nucleic acid molecules and proteins or only proteins, an individual is a small and simple structure that contains only one nucleic acid (DNA or RNA). Without a cellular structure, viruses cannot replicate themselves, but instead, insert genes into host cells and use the latter’s replication system to replicate new viruses. Common infectious diseases are usually RNA viruses, such as influenza virus, HIV virus, H1N1 virus, etc.

After the collection of virus samples,  stored and transported in a virus preservation solution to maintain the activity of virus samples and prolong the survival time of viruses in the samples.

Throat swabs include nasopharyngeal swabs and oropharyngeal swabs.

Generally, those collected from the mouth are called oropharyngeal swabs, and those collected from the nose are called nasopharyngeal swabs.

Covid Test Throat Swab

Covid Test Throat Swab

Things to look out for when taking an oropharyngeal swab:

1. First, check personal information with the subject before sampling.

2. Check the patient’s name again after sampling.

3. Put it in a sealed bag and a special transfer box, and quickly send the sample to the laboratory for testing.

4. Because collecting throat samples may cause throat discomfort.

Prohibit:  take throat swabs after a full meal or after drinking alcohol, and you must pay attention to not drinking, smoking, or chewing gum 30 minutes before sampling betel nut etc.

5. Before sampling, avoid eating irritating and strong-flavoured food and eat lightly.

6. 30 minutes before specimen collection, do not use mouthwash with antiseptic drugs or apply anti-inflammatory drugs to the throat.

7. You should take the initiative to cooperate with doctors to check personal information and inform the medical condition, so as to facilitate cooperation.

8. In order to improve the accuracy of the results, before sampling, wear a mask to cover your mouth, nose and cough, tilt your head slightly and cooperate with the doctor to say “ah~” for collection.

9. You may feel vomiting after collection, but please do not spit anywhere. You bring paper with you, wrap the spit in the paper, and put it in a unified trash can for disinfection. Always do personal disinfection after arriving home, such as washing hands, laundry, etc.

Precautions:

Viral Transport Media Kit With Flocked Swab Manufacturer

Viral Transport Media Kit With Flocked Swab Manufacturer

1. When the flocked swab is put into the tube, it should be placed vertically, and do not wipe the mouth of the bottle to avoid contamination.

When placed in the transfer box, it should be placed vertically to avoid liquid leakage.

2. It is best to send/deliver to the laboratory for inspection on the day of sampling.

3. Appropriate specimens must be consistent with the submission form before submitting for inspection.

The appearance of the sampling tube must be clear and famous with basic information.

Specimens without basic information cannot be tested; the specimens submitted for inspection must be submitted (or electronically submitted in advance) for the screening information form. 

Submission form and other materials, the materials submitted should be ensured not to be contaminated, and not to be placed with the specimen.

4. In order to prevent cross-section during sampling,  avoided within 2 hours after the patient eats.

5. During the collection process, the throat swab should not touch other parts to ensure the accuracy of the specimens left.

6. When deciding to do a throat swab, please do not use antibacterial drugs.

7. The depth of throat swab collection and the length of mucosal contact time. When collecting throat swabs, if the sampling time is not enough or poor quality swabs are used because the subject’s vomiting reaction is relatively large, it may cause false negatives and cause the patient to delay treatment.

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).

Flocked Nasopharyngeal Meaning Swab Test Sample Collection Vtm Kit

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?

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

Posted on by

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

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

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!

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

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

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.
Know the internal program processor of the laboratory. Or use a cotton swab to test the transport tube.
Send the sample to the lab for immediate testing.
In the laboratory, when taking clinical samples, wear protective gloves and protective equipment related to general precautions.
The conditions, timing, and volume of samples collected for clinical research are variables for obtaining reliable results. Follow recommended sample collection guidelines.
CellMedical swabs should only be used by personnel.

How to Perform Mrsa Nasal Swab

How to Perform Mrsa Nasal Swab

Methicillin-resistant Staphylococcus aureus (MRSA) is increasingly rampant, and its infection spreads almost all over the world.

Together with AIDS and hepatitis B, it has become the three most difficult infectious diseases in the world.

How to prevent and control MRSA has become a problem that we cannot ignore.

The long-term treatment of MRSA infection, in addition to the direct economic burden on patients, will also generate some indirect costs, such as isolation, disinfection and so on.

n response to the prevalence of MRSA, we should propose strict detection and control measures.

MRSA screening is an important part of this.

Medical swabs are one of CellMedical’s specialties. Our goal is to ensure that our swabs give end users what they really need so they can always perform at the highest level.

In this article, we review what MRSA is, why using a nasal swab is the most effective way to test for MRSA, and how to perform a nasal swab test for MRSA.

What is MRSA?

MRSA, known as Methicillin-Resistant Staphylococcus aureus.

A highly drug-resistant strain of bacteria found mainly in people with long-term chronic diseases.

It is naturally resistant to penicillin and cephalosporin antibiotics, and also has varying degrees of resistance to commonly used erythromycin, etimicin, ofloxacin and other drugs.

Mainly seen in patients with bloodstream infection, lung infection and other site infections.

If the treatment effect is not good after a variety of antibiotic anti-infection treatment, it is necessary to consider whether there is mrsa infection. This bacterium is only effective against antibiotics such as vancomycin, teicoplanin, and linezolid.

MRSA is contagious through person-to-person contact and when a contaminated person touches an object or surface and leaves behind germs that can spread.

About 126,000 people are hospitalized and 19,000 die from the bacteria each year.

MRSA Nasal Swab

A nationwide cross-sectional study of MRSA screening in more than 10,000 patients showed that screening sites included the nose, throat, underarm, perineum, and wound or implant sites. Nasal swabs identified only 66% of MRSA carriers, and further swab testing could increase the detection rate.

Nasal and perineal swabs were identified in 82% of patients, with the axilla being the least useful site for carrier identification (8% detection rate).

Standard screening methods should include at least two swabs (nasal swab plus perineal or pharyngeal swab).

According to the American Society for Microbiology, nasal swabs have a higher detection rate of MRSA than traditional swabs. Flocked swabs provide better sample collection because their brush-like tips release more target cells and retain more liquid sample than foam swabs.

Our flocked-Swab sterile swabs are designed for the collection and transport of clinically significant bacteria.

With molded breakpoints, sampling is fast, safe and convenient.

How to use MRSA Swab?

Once a sampling swab and transfer medium, such as CellMedical’s flocked-Swab media transfer system, has been selected, testers should wash their hands and wear clean gloves.

The process is as follows:

  1. Remove the nasal swab.
  2. Measure about 2 cm with a swab and mark with your finger.
  3. Insert a cotton swab about 2 cm (about 3/4 inch) into one nostril.
  4. Insert the swab into the nostril perpendicular to the nose (face), rotate the swab against the anterior nasal mucosa for 3 seconds, then gently rotate 3 times. .
  5. Using the same swab, repeat for the other nostril.
  6. Place the swab back into the virus delivery medium.
  7. Place the end of the swab firmly so that the tip of the swab is in contact with the wet swab.
  8. Tighten the cap of the tube, mark it well, and put it in a plastic bag and seal it.

Covid Swab testing include nasopharyngeal swabs and oropharyngeal swabs.

A sample taken by a doctor from a patient’s nasal cavity via a nasopharyngeal swab to test for Covid-19.

The oropharynx refers to the detection of secretions mainly from the soft palate, tonsils and other parts of the patient.

We need to pay attention to protection for nucleic acid testing.

The advantage of nasopharyngeal swabs over oropharyngeal swabs is that they are easy to operate.

The operator can stand behind the patient’s side, with only the nostrils exposed, without looking directly into the patient’s mouth.

There is basically no gag reflex, and the exposure risk of the sampler is lower than that of nasopharyngeal swabs.

How to do a covid nasopharyngeal swab without pain?

Since the flocked swab sampling is from the lower nasal passage all the way to the bottom of the nasopharynx.

It is more painful to perform, but in this process, the more nervous and conflicted, the more uncomfortable it will be during sampling.

Therefore, when doing a nasal swab, recommended to relax a little, then tilt your head back, keep still.

And use your nose to inhale and exhale through your mouth.

The collector will make this process quick and generally not too painful.

Does nasopharyngeal swab bleeding affect test results?

It will not affect.

Bleeding when taking a nasal swab is due to the rupture of capillaries in the nasal mucosa when the specimen is taken.

However, under normal circumstances, as long as the secretions from the nasopharynx are collected.

A small amount of bleeding will generally not affect the test results. have an impact.

However, if the secretions from the nasopharynx are not collected during the bleeding.

It is necessary to resample the nasal cavity on the other side after stopping the bleeding by resting.

Therefore, when doing a nasal swab, it is recommended to relax and listen to the collector.

So that sampling can be completed quickly.

Which is more accurate, nasal swab or throat swab?

It has been reported in the literature that when taking samples for SARS-CoV-2 virus nucleic acid detection, the results obtained by simultaneously sampling throat swabs and nasal swabs are generally equivalent.

Therefore, for a nasopharyngeal swab and pharyngeal swab, there is no special regulation on which one to do. It is recommended that those who need to do sampling can choose according to their own conditions. If they can tolerate pharyngeal swab collection, they can do pharyngeal sampling. After the nasal swab was collected, a nasal sampling was performed.

Can nasopharyngeal swab be made by themselves？

Not.

Since the nasal swab test needs to insert the swab deep into the nasal cavity to collect samples, there may be adverse reactions such as pain, gag reflex, tearing, and even nosebleeds during the process, causing physical discomfort and psychological discomfort to the collected person. The sense of resistance will be very strong, so there are highly professional requirements for the sampling personnel, and they cannot be done by themselves.

The person who did a few nasal swabs tells you how to do it without pain.

I’ve done nasal swabs several times and it’s been painless every time. Much more comfortable than a throat swab.

I see a lot of people on the Internet saying that the nasal swab is very painful, sour and straight to the sky, this is because your posture is not correct! !!

How Accurate Is The Nasal Swab

Nasopharyngeal swabbing is generally the preferred method of specimen collection for COVID-19 testing.

Looking at this schematic diagram, in fact, no matter the nasal swab or the throat swab.

Their purpose is to let the flocked swab sample from the inner wall of the throat.

Nasal swabs are not meant to poke your heavenly lid!

Nasopharyngeal culture

A nasopharyngeal culture is a test that examines a sample of secretions from the uppermost part of the throat, behind the nose, to detect organisms that may cause disease.

Nasopharyngeal Swab Pcr Test

Nasopharyngeal Swab Pcr Test

Therefore, you should tilt your head as far back as possible to allow the cotton swab to go in horizontally.

That way the only thing you feel is a little bit of cold, and it’s over in less than 5 seconds.

But if you keep your head upright, then the flocked swab can only be poked from bottom to top, which will definitely pierce the upper part of the nasal cavity.

That position is very sensitive, and it will hurt very much when pierced.

And because the doctor can’t see the location, he can only stir in it by the feel of the hand, so you will be sour to tears.

One sentence summary: Tilt your head back and let the flocked swab go in and out horizontally all the way.

Why you should take the swab test.

This test identifies viruses and bacteria that cause upper respiratory symptoms.

These include:

Bordetella pertussis, the bacterium that causes whooping cough Meningococcus meningitidis.

The bacterium that causes meningococcal meningitis is Staphylococcus aureus, the bacterium that causes staph infections Methicillin-resistant Staphylococcus aureus virus infection.

For example, influenza or respiratory syncytial virus cultures can be used to help determine which antibiotic is appropriate to treat infections caused by bacteria.

Normal Results The presence of common organisms in the nasopharynx is normal.

What an abnormal result means The presence of any disease-causing viruses, bacteria or fungi means that these organisms may be causing your infection.

Sometimes, organisms like Staphylococcus aureus can exist without causing disease.

The test can help identify resistant strains of the organism (methicillin-resistant Staphylococcus aureus, or MRSA) so that people can be quarantined if necessary.

Risks There are no risks to this test

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.

The new crown epidemic is a matter of public defence that we can’t avoid and can’t hide from.

I believe everyone knows the impact of the new crown epidemic on us.

I believe you all know the impact of the new crown epidemic on us.

As the number of COVID-19 cases across the country starts to climb again.

Everyone has started to discuss it again, and I believe that no topic can attract the attention of the world for such a long time like our current global new crown virus.

Some of us have raised such a question, why do we have two detection methods for nucleic acid detection points.

One is for extraction in the nose, and the other is for extraction in the mouth?

Nasopharyngeal swabs and oropharyngeal swabs only take different paths.

The oropharyngeal swab is to collect oropharyngeal specimens by entering the sampling swab through the mouth.

The nasopharyngeal swab is to collect nasopharyngeal specimens through the nose.

The is a matter of public defence that we can’t avoid and can’t hide from.

2. How to effectively collect nasal samples for patients

  • Place the entire tip of the swab into the nose and rub one side of the swab as much as possible against the wall of the nostril (also called the anterior nostril) with moderate pressure.
  • Use the same cotton swab to do four to five sweeps in each nostril for about 10-15 seconds per nostril. Both nostrils should be swabbed in order to collect an adequate sample.
  • Simply swirling the swab into the inner part of the nose or leaving the swab in the nose for 10-15 seconds is an inappropriate technique and may result in insufficient sample.

3. Features and advantages of disposable virus sampling tube (pharyngeal swab)

  • High safety: medical materials, good airtightness, good stability, prevent leakage and ensure biological safety
  • Various options: nasal/pharyngeal swab + inactivated/non-inactivated preservation solution to meet different experimental needs
