Flocked Swab With Vtm Kits Leading China Manufacturer

Posted on 2022年5月7日2022年5月18日 by Dr. Lee

What are flocked swabs used for?

Flocked swabs are widely used in Covid Test bacteriological sample processing, virological cell culture, DFA testing, rapid and direct testing, enzyme immunoassay testing, polymerase chain reaction and molecular diagnostic-based tests, and forensic identification. Both are ideal.

For throat sampling of respiratory viruses such as influenza, swine flu, bird flu, hand, foot and mouth.

Vtm Kits are used for the collection, transportation and storage of influenza, avian influenza, coronavirus and other virus samples for subsequent extraction and PCR amplification.

After samplers collect virus samples, they usually do not conduct PCR testing at the sample collection site in time.

So the collected virus flocking swab samples need to be transported. The virus itself will rapidly decompose in vitro, affecting subsequent detection. During transport, we need to add a virus preservation solution (virus transport medium).

For different detection purposes, we need to use different virus preservation solutions.

At present, it mainly includes inactivated type and non-inactivated type. In order to meet different detection requirements and different laboratory conditions for virus detection, it is very necessary to use different preservation solutions.

Sterile Flocked Nasopharyngeal Swab, 100% nylon flocked swab that provides exceptional absorption quality.

The principle of flocking swab precipitation.

1. Through the directional friction effect of the fiber layer of the flocked swab, the laboratory operator can complete the cell sample.

The unique structure of the top of this swab can greatly increase the number of samples collected

2. Flocked Swab is ideal for collecting large amounts of cells & rapid elution of the specimens instantly released into the transport medium.

More than 95% sample release rate. Very easy to elute.

3. The capillary movement between the nylon fibres at the top of the flocking swab forms a strong hydraulic pressure for absorbing liquid or cell-like samples.

Why flocked swabs are more beneficial for micro DNA collection.

1. The top of the traditional cotton swab, may even lead to false-negative results of the test.

2. The top of the flocking swab has a unique structure, which can almost completely extract and separate trace DNA, so the flocking swab has more obvious advantages in collecting trace DNA.

Made of non-inhibitory DNA amplification materials. It has been verified that it can be directly amplified by PCR, eliminating the need for extraction steps.

About viral transport media

At present, it mainly includes two types: inactivated and non-inactivated.

Flocked Swab With Vtm Kits Leading China Manufacturer

Inactivated preservation solution:

It can lyse and inactivate the virus in the sample so that the virus loses its infectious activity.

It can effectively prevent the secondary infection of operators.

But it also contains inhibitors, which can protect the viral nucleic acid from degradation.

Therefore, the experimenter can perform follow-up detection by NT-PCR.

Stored at room temperature for a long time, saving the storage and transportation costs of virus samples.

Non-inactivated preservation solution:

The non-inactivated preservation solution of the present invention can maintain the in vitro activity of the virus and the integrity of the antigen and nucleic acid, protect the viral protein shell, and maintain the originality of the virus sample to a large extent.

Not only for nucleic acid extraction and detection (PCR test) but also for virus culture and isolation.

ABOUT VTM kits and swabs manufacturer

What is viral transport medium ?

Posted on 2022年5月6日2022年5月6日 by Dr. Lee

Viral transport medium is a protective liquid medium added to the virus sampling tube to protect the samples after nasopharyngeal swab sampling and is usually called virus preservation solution in China.

Usually, in nucleic acid testing (PCR swab test), we cannot perform nucleic acid PCR directly at the sample collection site.

We need to add virus preservation solution (VTM) to the samples collected by swab for transfer check.

What is a virus?

Viruses are microorganisms whose structure is very simple.

There is no way to complete the process of self-replication.

They need the help of host cells and the nutrition of the host to complete virus replication.

The virus can infect humans as well as many other animals.

Influenza viruses such as common infectious diseases are usually RNA viruses.

There are many common viruses that cause human infection, which can cause respiratory diseases, such as cold virus, influenza virus, HIV and influenza A virus.

Since it has no cellular structure of its own, the virus itself cannot replicate.

But invades the gene into the host cell and replicates the new virus with the help of the latter’s replication system.

In conclusion, viruses are diverse and can cause damage to multiple parts of the body. “

After the virus sample is collected, in order to maintain the activity of the virus sample and prolong the survival time of the virus in the sample, the sampling swab ( flocking swab ) will be put into the preservation solution ( viral transport media ) for preservation and transportation.

What is the viral transport medium used for?

PCR test

The inactivated viral transport medium can perform protein denaturation on fresh clinical virus specimens to inactivate the virus. Prevent secondary infection and ensure the safety of transportation and testing personnel. The inactivated samples can be used with a variety of virus extraction kits.

The nucleic acid extraction instrument can quickly extract nucleic acids.

At the same time, with the respiratory pathogen PCR detection kit (VTM Kits) to achieve rapid detection. The specificity and sensitivity are not affected.

Virus preservation solution has many functions:

1. The operation is simple, and the liquid contains ingredients that can denature proteins, thereby inactivating the virus;

2. Contains inhibitors to protect the stability of viral nucleic acid to a greater extent and greatly improve the nucleic acid extraction rate;

3. Stored at room temperature for 12 months before sampling.

The airtightness is good, which is convenient for storage and transportation and saves transportation costs.

Cell medical (Dongguan) Co., Ltd.

Viral transport media include inactivated and non-inactivated viral transport media.

Contains Hank‘s Liquid, Potassium Chloride, Magnesium Chloride, Calcium Chloride, BSA, etc. The combination of various antibiotics has antibacterial and antifungal effects. Bovine serum albumin (BSA), as a protein stabilizer, can form a protective film on the protein shell of the virus. Making it difficult to decompose and ensuring the integrity of the virus; Hank’s buffer The neutral environment constructed by the agent helps to increase the survival time and infection stability of the virus.

What is viral transport medium?

Nasopharyngeal Swab

Inactivated and non-inactivated virus preservation solutions: usually used for the collection and transportation of clinical influenza, avian influenza, hand, foot and mouth virus, measles and other virus specimens, as well as specimens such as mycoplasma, ureaplasma, chlamydia, etc.

1. For monitoring and sampling of infectious pathogenic microorganisms by disease control departments and clinical departments.

It is suitable for a sampling influenza virus (common influenza, highly pathogenic avian influenza, H1N1 influenza virus, etc.), hand, foot and mouth virus and other types of viruses.

2. To transport nasopharyngeal flocked swab specimens or tissue specimens from specific parts from the sampling site to the testing laboratory for PCR extraction and detection.

3. Preserve nasopharyngeal swab samples or tissue samples from specific parts for necessary cell culture.

Deep Nasal Swab Virus Respiratory Kit

Posted on 2022年4月30日2022年4月30日 by Dr. Lee

As of April 30, local time, the number of new coronavirus patients in the United States has reached 81.2 million, and the number of deaths due to new coronavirus infection has exceeded 992,000.

As the government ramps up testing for Covid-19, many of us ordinary people are now being tested for Covid-19.

What is Deep Nasal Swab?

Deep Nasal Swab ( nasopharyngeal swab ) is actually a relatively long collection swab, similar to a relatively long sterile swab.

Its main function is to take nasopharyngeal secretions for bacterial culture and drug sensitivity tests.

The source of infection in the nasopharynx and the microorganisms in the nasopharynx were selected and identified by bacterial culture and drug sensitivity test.

Then a drug susceptibility test can be done to determine which drugs are sensitive so that sensitive drugs can be selected for treatment.

So that a better curative effect can be achieved, so the nasopharyngeal swab is actually a flocking swab for collecting nasopharyngeal samples.

China Sterile Flocked Nasopharyngeal Swab GMP Factory and Manufacturers.

Why deep nasal swab for covid?

The Deep Nasal Swab test: to collect cells deep in the nasal cavity because the nostrils by themselves do not provide a sufficiently accurate sample.

The collected fluid samples are sent to a laboratory for PCR testing (polymerase chain reaction), a standard scientific procedure that involves using samples provided by patients to build models of their DNA.

In this system, technicians can look for evidence of the genetic material (RNA) from the new coronavirus, which is wrapped in the patient’s own DNA if they are infected with the virus.

Both Public Health England and the US Centers for Disease Control and Prevention (CDC) prefer to use Deep Nasal Swab because it is so accurate.

Unfortunately, for suspected Covid-19 patients, it can be uncomfortable.

During the operation, the medical staff is gentle and skilled, so there will be no pain.

What is the correct depth and length of nasopharyngeal swab collection?

See the length of the nasal swab? See how deep it goes into your nostrils?

The length of the nasal swab is normally about 15cm, and it should enter about 2/3 of the time when doing the collection.

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

About the distance from the tip of the nose to the earlobe, insert a thin cotton swab into the nostril, from the lower nasal passage to the posterior wall of the nasopharynx, and then turn the front to take a sample. The swab will have a significantly insufficient depth of entry. So the posture must be correct.

When the throat swab enters in the direction of the earlobe if it encounters resistance, it needs to adjust the direction, rotates it slightly, and cannot forcefully enter it.

Otherwise, damaged. Until the bottom of the rhinitis is reached, there is a general sense of resistance against a wall.

When you feel a sense of resistance, you have reached the bottom of the nasopharynx. At this time, you need to keep the nasopharyngeal swab at the bottom of the rhinitis for 10-15 seconds. After fully contacting the secretion, rotate it and pull it out.

Deep Nasal Swab Manufacturer Virus Respiratory Kit

Specifically designed for the collection, transport and preservation of virus-containing samples such as influenza, covid-19, avian influenza, and respiratory viruses such as hand, foot and mouth. 2-8 ℃ can be stored and transported for a short time, long-term storage should be at -80 ℃ or below.

Anterior Nasal Swab VS Nasopharyngeal Swab

Posted on 2022年4月21日2022年4月21日 by Dr. Lee

How do avoid damage to the nasal cavity through nasal swab sampling for nucleic acid detection and antigen detection? Rhinitis patients should pay attention to what?

Standardized collection methods for nasopharyngeal swabs :

Nasopharyngeal Swab

1. The sampler lightly supports the head of the person to be collected with one hand, and sticks the swab into the nostril with the other hand.

And slowly penetrates backward along the bottom of the lower nasal passage. Because the nasal passage is curved, do not use excessive force to avoid traumatic bleeding.

2. When the top of the swab reaches the back wall of the nasopharyngeal cavity, gently rotate it for one week. (If you have a reflex cough, it should stay for a while). Then slowly take out the swab, and immerse the swab head in the matching test strip. In the sampling tube of the virus transport medium.

The nasopharyngeal collection method collects a sample from the nasopharynx, which is the upper part of the throat behind the nose.

Nasopharyngeal Swab Pcr Test

In this test, a small pointed flocked swab is inserted into the nostril parallel to the chin until resistance is felt.

Inserted no deeper than half the distance between the nostril and the ear.

The swab is then swirled a few times while remaining in place, and then slowly removed while gently swirling.

If the flocked tip of the swab is completely saturated with the sample, it may not be necessary to collect samples from both nostrils.

This method is often less comfortable for the patient but is generally not considered painful.

This method is not recommended for self-testing and should only be performed by a healthcare practitioner.

Swabs for use in the nasopharynx are designed with a micro-tip made of ultra-fine flocked material and a thin, flexible handle usually made of polystyrene.

Standardized collection methods for nasal swabs (anterior nasal swabs):

Anterior Nasal Swab

1. The collected person first used toilet paper to remove the snot, and then tilted his head slightly.

2. The sampler lightly supports the head of the person to be collected with one hand, holds a swab with the other hand and sticks it into one nostril. And slowly goes back along the bottom of the lower nasal passage for 1-1.5 cm. And then sticks to the nasal cavity and rotates at least 4 times. (The residence time is not long. less than 15 seconds). Then repeat the same procedure in the other nasal cavity using the same swab.

3. After slowly taking out the flocked swab, immerse the swab head in the sampling container containing the preservation solution that comes with the test strip.

Precautions:

1-1.5cm deep into the nasal cavity (about 1cm for children).
Rotate 4-5 times against the nasal cavity (time not less than 15 seconds).
Bilateral nasal collection from the same swab.

Standardized collection methods for oropharyngeal swabs (pharyngeal swabs):

Oropharyngeal sampling swab

1. The head of the person being collected is slightly tilted, the mouth is wide open, and the mouth shape is “ah”, exposing the pharyngeal tonsils on both sides;

2. Pass the swab across the base of the tongue, and wipe the pharyngeal tonsils on both sides of the subject with slight force back and forth at least 3 times.

And then wipe the posterior pharyngeal wall up and down at least 3 times.

And immerse the swab head in the preservation solution provided with the test strip. in the sampling container.

Why do nucleic acid testing (PCR swab test), and what can be detected?

Nucleic acid testing is to find direct evidence of the presence of the virus.

A positive nucleic acid test for the new coronavirus pneumonia indicates that the subject has the virus in the body and may be infectious.

If accompanied by fever, respiratory symptoms or other clinical characteristics of patients with new coronary pneumonia, combined with a positive nucleic acid test, a patient with new coronary pneumonia can be diagnosed; if there are no clinical symptoms and a positive nucleic acid test result, it can be determined as an asymptomatic infection. Therefore, nucleic acid detection is of great significance as a standard for diagnosing new coronary pneumonia.

Nasopharyngeal swab test and Anterior Nasal Swab test, which is better?

As we all know, nucleic acid detection generally takes throat swab detection, and throat swab detection is divided into nasopharyngeal swab detection, Anterior Nasal Swab, and oropharyngeal swab detection. The difference between them is that the sampling sites are different, but there is no essential difference. Most medical institutions use oropharyngeal swab testing because this testing method is less uncomfortable for the sample and more convenient for sample collection.

For the sampling of the new crown antigen professional version and home self-test version. Because this method is less invasive, and generally more comfortable for the patient.

When Taking An Oropharyngeal Swab Precautions

Posted on 2022年4月19日2022年4月19日 by Dr. Lee

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

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

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.

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?

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.

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.

What is Swab Test

Posted on 2022年3月8日2022年3月22日 by Dr. Lee

If you are considering whether you should get a COVID-19 swab test, symptomatic or asymptomatic.

Under normal circumstances, the virus is spread through the air to our nose or mouth.

We have to wear masks to prevent the infection of the virus from the source.

Assuming we are unfortunate enough to carry the new crown, the virus will enter the throat through the nose and mouth, and then enter the alveoli through the trachea and bronchi.

At this time, we will use nasopharyngeal swabs and oropharyngeal swabs. The sample is collected from your nasal cavity or mouth when the nurse’s sister gives you a nucleic acid test.

At this time, we will use nasopharyngeal swabs and oropharyngeal swabs, which are the samples taken by the nurse sister from your nasal cavity or oral cavity when you are doing nucleic acid testing.

Due to the convenient operation and high accuracy, these two methods have been widely used. Now I will tell you about nasopharyngeal swabs and oropharyngeal swabs in detail.

What is a nasal swab test?

Specimen Collection Swab

Our respiratory tract is divided into the upper respiratory tract and lower respiratory tract. The upper respiratory tract includes the nose, pharynx, and larynx. The lower respiratory tract includes the trachea, bronchi, and lungs. In medicine, the cricoid cartilage is used as the boundary to distinguish.

The nasopharyngeal swab test is a medical test method. A medical cotton swab is used to wipe a little secretion from the nasopharynx of the human body, placing it in a special incubator, and placing it in a temperature-controlled device for cultivation. Can understand the patient’s condition, oral mucosa and pharyngeal infection.

Compared with oropharyngeal swabs, nasopharyngeal swab sampling has the following advantages:

1. When collecting oropharyngeal swab samples, the sampler can see the location of the pharynx to be sampled, and the irritation to the oropharyngeal mucosa may cause the sampled to cough, nausea, and even vomit.

2. When collecting nasopharyngeal flocked swab samples, the irritation to the nasopharyngeal mucosa is relatively small if the operation is standardized.

3. But the sampler cannot see the location of the pharynx for sampling, and mainly relies on the resistance felt by the hand to complete the sampling, so the technical requirements are higher, and the tools used are also more complicated.

4. It can stay in the pharynx for a longer time to obtain a sufficient amount of specimens, which is why the positive rate of the swabs reported in the literature is higher than that of oropharyngeal swabs.

5. The patient’s tolerance is good. After the skilled operation, sampling can be performed without anesthesia, but surface anesthesia and contraction of the nasal mucosa can be performed first for beginners.
