93050 Throat sampling swab, ABS rod + nylon fluff head, used for sampling, the release rate is as high as 90%.

The nylon flocked swab is a honeycomb swab best suited for specimen collection. The nylon flocking technology has greatly improved the collection ability and elution ability of a sampling swab. And the flocking swab also marks the latest development of single-use specimen collection equipment. Flocking, which refers to the vertical attachment of long fibres to an adhesive-coated swab shaft, has a distinct advantage when collecting samples.

Features of flocked sampling swabs:

1. Swabs using jet-dense nylon fiber technology.

2. According to different analysis items, there are soft or brush texture swabs, and the collection volume has reached the limit.

3. Disposable sterile injection-moulded swab rod with breakpoint.

4. The flocking swab technology improves the adsorption/release of the specimen and improves the sensitivity of the analysis.

5. No sample retention, indicating faster and less sample transfer.

Used in the medical industry, such as collecting liquid microorganisms.

such as human mouth, nose, throat, cervix, DNA, viruses, bacteria, etc. Medical nylon flocking swabs are the best for sample collection.

As a professional sampling swab manufacturer, many people will ask us why we use flocked sampling swabs? You will know by looking at the comparison below.

Nylon flocked swabs: maximum sample collection/release capacity, release rate >80%

The acquisition is slow, the release is even slower.

The time for flocking swabs to collect samples is 3-5 seconds, while the time for cotton swabs is 15-120 seconds, or even longer, which causes pressure on staff during the diagnosis process. Only faster sample extraction can complete the collection and analysis more efficiently.

The sampling flocking swab is 3 times higher than the traditional wrapping swab to collect and release the sample, and it does not cause damage to the cell sample. It will not cause harm to the human body.

In short, the upright nylon fibers act like a soft brush to collect more cell samples. The capillary action between nylon fibers enhances the loading of aqueous samples, and the samples are concentrated on the surface of the swab for easier elution. Nylon flocked swabs can absorb and release more samples.

The nylon flocked swab is a honeycomb swab best suited for specimen collection. The nylon flocking technology greatly improves the collection and elution capacity of a single sampling swab. Flocked swabs also mark the latest development in single-use specimen collection devices. Flocking, which refers to the vertical attachment of long fibers to an adhesive-coated swab shaft, has a distinct advantage when collecting samples.

The epidemic is an order, prevention and control are a responsibility, and life is more important than Mount Tai.

One-time use of  Viral Transport Medium accelerates production, Cell medical (Dongguan) Co., Ltd. has a daily production capacity of more than 1 million sets of Viral Transport Media kits.

One-time use Virus Sampling Tube, Accelerated Overtime Production, 10ml Viral Transport Media Tube, 20ml Viral Transport Media Tube, 30ml Viral Transport Media Tube.

20-in-1: Pooled Sample Test, originally originated from a single set of samples to 5-in-1, 10-in-1, and maybe 30-in-1, 40-in-1, and 50-in-1 in the future.

The purpose of collecting and mixing is to improve efficiency and quickly screen positive patient samples.

How strong is the detection ability of 10 people’s sample nucleic acid (PCR test) mixed together?

The new wave of the epidemic has affected the hearts of people all over the world. Many people are cheering on the Internet to overcome the epidemic. However, in the recent period, the outbreak of asymptomatic patients and local confirmed patients has not yet reached an inflection point. cases increased.

Why do 10-in-1 Pooled Sample Test?

Mainly because of the following three advantages.

1. The speed of nucleic acid detection can be increased by 10 times.

Citizens line up in an orderly line for pcr swab testing

Citizens line up in an orderly line for PCR swab testing

In the past nucleic acid testing, each person took a test tube.

After the test, we put the sample into the test tube for preservation.

The samples of 10 people: Stored in a test tube.

If tens of thousands of people in the city do nucleic acid swabs alone.

Then, we need millions and tens of millions of collection tubes and a large number of medical personnel.

In this way, the speed of nucleic acid detection will be very slow. Unable to achieve the desired effect.

2. It can quickly identify the positive infected people in the crowd.

Now the infected people are all asymptomatic patients with fever and no cold. It is impossible to detect them by ordinary methods. Only through nucleic acid testing can the hidden dangers in the crowd be excluded.

If everyone is tested individually, the speed of nucleic acid testing will be particularly slow. Over time, people queuing for nucleic acid testing are likely to cause cross-infection.

Completing the test as soon as possible and excluding infected people from the crowd as soon as possible can also reduce the scope of infection, and the mixed detection method for each person can improve the speed and reduce the scope of infection.

If there is one positive in it, wouldn’t it cause cross-infection?

Even if the other nine were negative, they would definitely be implicated.

3. Can reduce the cost of nucleic acid testing.

Although in some places our nucleic acid tests are all free, and people do not need to pay a penny, that is because all these nucleic acid costs are paid for by our government.

Our government will uniformly purchase test reagents for nucleic acid detection, and then uniformly pay for some of the testing costs.

There are millions of people in a city, and the cost of these nucleic acid tests is a lot of money.

So what is the principle behind this 10-person sample being mixed together?

Nucleic acid detection using this mode is to deal with large-scale nucleic acid detection.

Each group of 10 people, after completing the test, put the flocked swab samples into a collection tube, and then centrally send them to the local laboratory for testing.

If these 10 people are all negative, then it proves that these 10 people are all safe and do not need separate isolation and separate testing.

If one of the 10 people is positive, the remaining 9 people will have special epidemic prevention personnel.

These 9 people will be sent to the isolation area for individual isolation, and then each person will be tested individually every day.

After 14 days of isolation, in In the past 14 days, the results of these 9 people are all negative, which can ensure safety and allow them to return to normal life.

Nucleic acid detection using this mode is to deal with large-scale nucleic acid detection.

Each group of 10 people, after completing the test, put the flocked swab samples into a collection tube, and then centrally send them to the local laboratory for testing.

When Taking An Oropharyngeal Swab

When Taking An Oropharyngeal Swab Precautions

Posted on by

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.

Viral transport medium with swab

The COVID-19 outbreak is expected to have a significant impact on the tedious market for swabs and virus transport media owing to the increasing patient demand for infection diagnosis.

Flocked Swab and viral transport media are expected to grow due to intensive testing of COVID-19 in research institutions and laboratories.

Rising research and development activities to produce COVID-19 vaccines are expected to drive market growth during the pandemic.

The rising number of COVID-19 cases in the global population is expected to drive market growth.

The need to develop vaccines and early diagnostics to treat infections is expected to boost the market growth.

Manufacturing of Viral Transport Medium

Virus sampling tubes are medical device products. The virus sampling tube consists of a sampling flocking swab, virus transport medium and outer packaging. Since there is no unified national standard or industry standard, the products of various manufacturers vary greatly.

CellMedical manufactures viral transport media (VTM) following WHO and CDC recommendations, with or without swabs.

Flocked swab+tube with Viral transport medium

1. Sampling swab:

Virus sample collection flocked swab

Virus sample collection flocked swab

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

　　Synthetic fibres such as PE synthetic fibers, polyester fibres, polypropylene fibers, and rayon fibres should be used for the manufacture of sampling swab tips.

　　(1) Natural fibers such as cotton are not recommended

　　Because the fiber of cotton has strong adsorption of protein, it is not easy to be eluted into the subsequent preservation solution;

　　(2) Nylon fibers are also not recommended

　　Because nylon fibers (similar to toothbrush heads) have poor water absorption, the sampling volume is insufficient and the detection rate is affected.

　(3) Do not use calcium alginate sponges or wooden stick swabs (including bamboo sticks) for the head of the sampling swab.

　　Because the broken wooden sticks or bamboo sticks containing calcium alginate and wooden components will also adsorb proteins after being soaked in the preservation solution, and even have an inhibitory effect on the subsequent PCR reaction.

4. Sterilized by ethylene oxide or irradiation, individually packaged;

Nasopharyngeal and oropharyngeal swabs. learn more

 

2. Virus preservation solution (virus transport medium): There are mainly two kinds of virus preservation solutions widely used in the market, one is a virus maintenance solution improved based on the transport medium, and the other is an improved nucleic acid extraction lysate. Preservation solution.

3. Virus sampling tube: The material of the storage tube should be selected carefully. Some data suggest that polypropylene (Polypropylene) is related to the adsorption of nucleic acids, especially at high tension ion concentration, polyethylene plastic (Polyethylene) than polypropylene (Polypropylene) Easier to grab 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 and contaminating when the swab is broken.

What is Virus Sampling Tube

Virus Sampling Tube

4. Water for production of preservation solution: Ultrapure water used for the production of preservation solution should be filtered by an ultrafiltration membrane with a molecular weight of 13,000 to ensure the removal of biologically derived polymer impurities, such as RNase, DNase and endotoxin, and ordinary purification is not recommended. water or distilled water.

About the use of virus sampling tubes

Sampling using virus sampling tubes is mainly divided into oropharyngeal sampling and nasopharyngeal sampling:

1. Oropharyngeal swab sampling:

first press the tongue with a tongue depressor, then insert the head of the sampling swab into the throat to wipe the bilateral pharyngeal tonsils and posterior pharyngeal wall, and wipe the posterior pharyngeal wall with mild force, avoiding touching the tongue department.

2. Nasopharyngeal swab sampling:

measure the distance from the tip of the nose to the earlobe with a swab and mark it with your fingers, insert the sampling swab into the nasal cavity in the direction perpendicular to the nose (face), and the swab should be inserted at least half the length from the earlobe to the tip of the nose. Leave the swab in the nose for 15-30 seconds, swirl gently 3-5 times, and withdraw the swab.

It is not difficult to see from the method of use, whether it is an oropharyngeal swab or a nasopharyngeal swab, sampling is a technical task, which is difficult and easy to contaminate. The quality of the collected samples is directly related to the subsequent testing. If the viral load of the collected samples Low, easy to cause false negatives, difficult to diagnose.

Most of the samples recommended by the kits currently on the market are oropharyngeal swabs or nasopharyngeal swabs and bronchoalveolar lavage fluid. This can greatly reduce the difficulty of the samplers’ work. After all, it is not difficult to collect venous blood samples, and like the detection of hepatitis C RNA, about 5 ml of EDTA anticoagulated blood samples are separated into plasma, and the extracted and purified RNA can fully meet the needs of PCR detection.

Preservation solution features:

Our independent research and development and production, unique cell preservation technology, can be stored at room temperature for more than 3 years after sampling! No need to refrigerate, store and transport at room temperature.

Flocked Swab

Flocked Swab

Nylon flocked swab

Made of nylon fibre flocking technology, the front end is coated with nylon short fibers fixed in a vertical manner.

Increasing the efficiency of collection and release of cellular and fluid samples.

So that there is no absorption hole in the entire collection area of ​​the swab.

The collected sample does not disperse and remains in the fibre, facilitating faster and more efficient elution.

Traditional spun cotton swabs cannot completely collect and elute the sample, while flocked swabs can elute more than 95 per cent of the sample collected.

So the use of flocked swabs has great advantages for a variety of sample collection applications.

Because most of the testing tools used for nucleic acid testing are disposable sampling swabs, we usually see more nasal swabs and throat swabs.

Improve analytical sensitivity, no sample residue, and speed up sample processing.

PS stickers come off easily. Suitable for cervical, nasopharyngeal, oral, forensic collection systems and DNA collection, etc. Individually packaged.

Flocked swabs are biocompatible and ideal for PCR work.

PCR is compatible, free of RNase and DNase, so the new flocked swabs are ideal and a good choice for scientists working with PCR technology.

Flocked swab sampling is more comfortable and easier to use;

CellMedical’s flocked swabs use the existing technology “spraying technology”, which is to vertically attach millions of nylon fibres to the head of the medical swab shaft through electrostatic charges in the flocking hair.

Flocked Nasopharyngeal Swab Suppliers and Manufacturers

Flocked Nasopharyngeal Swab Suppliers and Manufacturers

The vertical nylon fibres resemble a soft brush.

During sampling, the user will have no foreign body sensation.

In addition, different parts have different breaking points of the flocking swabs used, and the thickness of the swab rod is also different.

So there is a big difference in softness.

For example, for nasal swabs, the upper end of the swab rod is thin and soft, and the breaking point is also relatively back.

Swab Specimen Collection

Posted on by

A throat swab refers to the use of a sterile medical long flocked swab to dip a small number of secretions from the pharynx of the subject.

And then carry out the detection of respiratory viruses, bacteria and other pathogenic microorganisms.

The collection site of the throat swab is the pharynx and tonsils of the subject, and precautions should be taken when collecting.

Swab Specimen Collection details are as follows:

Swab Specimen Collection

Swab Specimen Collection

1. Drinking water before the oropharyngeal test strip will dilute the virus attached to the pharynx, especially drinking hot water will inhibit the activity of the virus.

In order to improve the accuracy of the nucleic acid detection of throat swabs, required 15-30 minutes before the test. Do not drink water to ensure the high accuracy of throat swab nucleic acid detection;

2. We do not recommend that patients with well-exposed larynx keep hair in order to reduce the occupational exposure risk of the sampler;

3. To prevent vomiting, avoid eating two hours before collecting throat swab specimens;

4. Do not smoke, drink, or chew gum half an hour before sample collection.

In addition, the basic steps of throat swab collection are:

1. Ask the patient to sit down, tilt their head back, open their mouth wide, and take out the surface secretions in the nasal cavity;

2. The sampler fixes the tongue with a tongue depressor, and uses a cotton swab to cross the base of the tongue to the posterior pharyngeal wall and the lateral wall of the tonsillar recess, etc.;

3. Wipe 3-5 times repeatedly to collect mucosal cells;

4. Gently remove the test strip, avoid touching the tongue, uvula, oral mucosa and saliva;

5. Insert the test strip back into the sampling device or a suitable transfer device.

There are various Specimen Collection swabs available on the market.

Which one is the best one to choose?

CellMedical recommends “synthetic flocked swabs“.

Compared with traditional wound swabs (although they are also made of synthetic fibres), the amount of samples collected and released by this swab is 3 times higher, and it does not damage the cell samples, which can ensure the survival rate of the cell samples and has no fatty acid residues. Contains substances that inactivate certain viruses and inhibit PCR detection.

Nasal Gene Sampling Flocked Swab Oral Gene Sampling Flocked Swab

Although the positive rate of the new coronavirus RNA test is directly related to the quality of the reagent itself, the quality control of the whole process is more critical, which includes sample collection, transportation, storage, testing and all consumables used for testing. As long as one step is not well controlled, it is difficult to achieve the quality (detection rate) of the reagent itself.

What is the most reliable test for COVID-19?

What are the tests for COVID-19?

Oral swabs and nasal swabs or saliva. In the experiments, oral flocked swabs were used to collect samples from the oral cavity for the oral examination.

This is different from a saliva test, which spits saliva into a small container.

COVID-19 Test, there are usually two main types of tests:

There are two main methods of nucleic acid detection: acid detection reagents and antibody detection. The first method is usually PCR detection through throat swabs, gene amplification, and then nucleic acid detection.

The antibody test is to choose blood, the method of blood draw to see the results, to observe whether the antibody titer increases.

How to do a mouth swab for COVID-19?

1. Rinse your mouth with water 30 minutes in advance (no toothpaste, especially breastfed babies need to drink a few mouthfuls of water, and no mouthwash);

2. Mark the envelope with a pen (eg: father, mother or child) and date of collection, name.

3. Hold the CellMedical flocked sampling cotton swab in one hand, put it into the left (right) inner buccal mucosa of the mouth and wipe it repeatedly for 15-20 times (rotate the genetic sampling cotton swab while wiping).

Take out the genetic sampling cotton swab, put it on the envelope or white paper, and dry it in the shade for more than ten minutes until the saliva is completely dry; (the specific location for wiping is the side of the cheek or the inside of the cheek and cheek – for example, the place where the adult pinches the child’s cheek, from the wipe in the mouth)

4. Collect the second cotton swab (the other side) in the same way, and extract three (six in total) genetic sampling cotton swabs from each side;

5. For gene sampling after drying in the shade, we should put the collection cotton swabs in a marked envelope and seal it (please do not use plastic bags or plastic wrap for the sampling cotton swabs)

6. Take the sample to the laboratory as soon as possible for PCR experiments, or you can choose to mail it to the laboratory or hospital.

How to Obtain an Oral Swab Specimen

If you have been in close contact with symptoms of COVID-19 (15 minutes or more in six minutes), you should get tested.

If you have recently been to someone in an area with a positive case, you should do a swab test;

You are a person who recently travelled or travelled for business, you should take the test;

If you and your family members have recently developed suspicious persons such as fever, dry cough, fatigue, sore throat, and decreased sense of smell (taste) during the self-health monitoring process, you should go for a test;

If you have recently held or participated in large-scale, crowded dinners, parties, conferences, training and other large-scale gatherings of people, you should go to the test.

You can talk to your healthcare provider, your local urgent care, or your state or local health department about where to go to get tested (CDC, 2020A).

What is the most reliable test for COVID-19?

You may have seen the rumour circulating that oral swab tests are not as reliable as nasal swabs. But how is this measured?

Expert research has shown that nasal swabs are easier to detect nucleic acid positive, and the sampling time stays longer in the nasopharynx. Larger doses of samples can be obtained, which is the reason for the higher positive rate of nasopharyngeal swabs reported in the literature.

1. Polymerase chain reaction: fluorescence quantitative PCR, which is suitable for a large number of samples and has a low cost;

2. Second-generation gene sequencing: the NGS method, which is more accurate and can read out which generation of nucleotides and viruses the data came from.

For example, the complete data of the nucleotide sequence of the delta virus is available in the database. We compare the resulting virus to the full data, and if we do, it’s a delta virus. There will be subtle differences in the process of virus transmission, even the first and second generations are different, and subtle differences can be found through comparison. Therefore, it is possible to find out who and where the first-generation patient, patient No. 1, came from during the outbreak of this virus in this local community. It is better to use the NGS method to trace the source of the virus.

Both methods have their own advantages and disadvantages, and both can very accurately reflect whether the nucleic acid test is positive or not, and both can achieve the purpose of detection. If we need traceability. We compare the collected viral nucleotides with viral databases in all databases to aid in diagnosis and guide treatment.

Still, the information on testing for the new coronavirus continues to evolve, to the point where you may feel like you need to become a medical professional or even know where to go first. If you’re wondering whether to get tested and how it works, we’re here to help. Here’s what you need to know about COVID-19 testing and other options.
