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.

Pooled Sample Test Viral Transport Media Kits Manufacturer

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

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

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.

Medical Swab Test Kit specimen collection sterile nylon flocked swab

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.

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.

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.

Viral Transport Medium Tube Suppliers

　　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.

Viral Transport Medium with Flocked Swab

　　In addition, we also provide inactivated virus sampling tubes, which can make the sample infective. Thus improving the safety of sample storage and transportation. The product is supplied in bulk liquid medium for further processing, such as into smaller sample tubes.

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.

What Is Virus Transport Medium

Posted on 2022年3月28日2022年3月28日 by Dr. Lee

The virus transport medium is novel and unfamiliar to many small partners, but it is of great significance for the detection of various viruses.

The new crown virus has tortured human beings enough.

In the face of a large number of COVID-19 patients, some places are still rising.

Therefore, as soon as there are new additions, many places will focus on the new crown nucleic acid detection.

The virus preservation solution plays a very important role.

Virus Transport Medium with Specimen collection swab

At present, the nucleic acid detection of the new coronavirus is mainly the detection of viral nucleic acid.

Virus transmission medium is a cell preservation liquid, which protects the virus to be detected by immersing the flocked swab head with the virus sample into the transport tube.

It is mainly suitable for the new coronavirus, Collection, preservation and transportation of common virus samples such as the influenza virus.

To collect throat swabs, nasal swab or tissue samples from specific parts.

The stored samples: for subsequent nucleic acid detection or clinical experiments such as virus culture.

Since the virus is a parasitic organism, it cannot survive outside the body after sampling.

If it cannot be detected in time, it needs to be placed in a virus preservation solution for preservation. (Virus Transport Medium)

In order to protect the safety of the virus detection environment and the safety of the detection personnel, inactivated virus preservation solution is actually a better choice!

FLOCKED SWAB

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

The two widely used preservation solutions have their own characteristics.

In order to meet different detection requirements and different experimental conditions for virus detection, it is necessary to use different preservation solutions.

The inactivated virus preservation solution can inactivate the virus.

How to detect it after inactivation?

The purpose of our use of inactivated preservation solution is to lyse nucleic acids, release nucleic acids and then carry out nucleic acid detection by subsequent real-time fluorescent RT-PCR.

Doctors use inactivated virus transport media to determine whether the sample contains virus characteristic nucleic acid, that is, whether we carry the virus.

Inactivated virus transport medium:

A virus lysis type preservation solution improved by nucleic acid extraction lysis solution.

Effectively prevent the secondary infection of the operator, but it also contains inhibitors, which can protect the viral nucleic acid from being degraded.

This enables subsequent detection by NT-PCR.

Moreover, stored at room temperature for a relatively long time, which saves the cost of virus sample storage and transportation.

Non-inactivated virus transport medium:

A virus maintenance liquid type preservation solution improved on the basis of the transport medium.

It maintains the activity of the virus in vitro and the integrity of antigens and nucleic acids.

The protective viral protein shell makes it difficult to decompose and maintains the originality of the virus sample to a great extent.

For nucleic acid extraction and detection, the experimenters also use the transport medium for virus culture and isolation and maintain the activity of virus samples.

In addition to nucleic acid extraction and detection, the inspector also uses this preservation solution for virus culture, isolation and antigen detection.

Nasopharyngeal (NP) Swab VS Oropharyngeal Swab

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

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.

Np Swab Covid Test Meaning

Posted on 2022年3月16日2022年4月7日 by Dr. Lee

Np Swab Covid Test Significance Np Swab is the English abbreviation of nasopharyngeal swab.

This article provides information on how to properly perform nasopharyngeal swab sampling, how to analyze samples taken from swabs.

Nasal swab? What is the difference between a nasopharyngeal swab and a nasal swab?

Nasopharyngeal Swab Pcr Test

Nasopharyngeal Swab vs Nasal Swab (Anterior Nasal Swab)

What is the method of nasopharyngeal swab?

Collection of specimens from the surface of the respiratory mucosa with nasopharyngeal flocked swabs is a procedure used for the diagnosis of Covid-19.

A nostril sample collection is usually one of the nursing care.

What is the nasal swab technique?

Part of the inspection method is done using sub-diagnostics and collecting diagnostic samples from the membrane. Rotate for 10-5 seconds while touching both walls, then use a cotton swab with 1 mid-hole in one nostril.

In the same way in the other nostrils: usually preferred for people – and used in my own testing. The same goes for technology.

Which swab test is more accurate?

Nasopharyngeal swabs are generally the recommended sample collection technique for COVID-19 testing.

Additionally, a 2012 comparative study showed no significant analytical differences between the two influenza detection technologies.

In addition to being the typical testing approach for the diagnosis of COVID-19.

The nasopharyngeal swab: is likewise regularly utilized for the detection of different viruses and bacterial infections.

How do we perform nasopharyngeal swab sample collection?

Flocked Tip Swab

Healthcare experts need to execute these tests in a specialized and also sanitized room that prevents the spread of the infection.

All healthcare specialists administering the nasopharyngeal swab examination have to wear the suggested personal protective devices (PPE), of which ought to include an N95 mask, non reusable cap, goggles, dress, latex gloves, and also footwear covers.

When the individual sitting upright as well as their head in a straight position, as this provides very easy exposure and also access to the nasal floor, which is vertical to the facility axis of the person’s face.

The staff places the swab into the client’s nose in the same direction as the nasal cavity and diaphragm floor.

As long as there are no obstructions existing within the nasal dental caries, the swab will certainly remain to relocate this instructions until it reaches the nasopharynx.

Once the swab reaches the nasopharynx, finishes two full 360-degree rotations to enable the secretions from this area.

When we take the swab out of the individual’s nose. Immediately insert into a vial with medium.

Nasopharyngeal Swab Procedure.

What can a nasopharyngeal swab find?

As previously pointed out, a nasopharyngeal swab: is extensively utilized to identify (SARS-CoV-2) infection, which is the infection that causes COVID-19 disease.

Identified via nasopharyngeal swabs, several of which include rhinovirus, and adenovirus. flu. respiratory syncytial virus (RSV). (HPIV). (HMPV) as well as (EV).

Given that the nasopharynx is generally home to a high number of both nonpathogenic as well as pathogenic microorganisms. This testing approach can additionally be utilized to detect particular bacterial pathogens.

Such as Streptococcus pneumoniae, Haemophilus flu, as well as Moraxella catarrhalis.

A diagnostics firm, for example, has just recently presented a novel nasal swab that gathers nasal epithelial cells for the early molecular discovery of lung cancer in both current as well as previous smokers.

We obtained nasopharyngeal swab samples, and the current standard for diagnosing SARS-CoV-2 is real-time fluorescent polymerase chain reaction (RT-PCR).

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

Commonly, the RT-PCR test will measure several various RNA gene targets, such as several of the envelope (env), nucleocapsid (N), spike (S), RNA-dependent RNA polymerase (RdRp) as well as ORF1 genes.

RT-PCR test is an analytical technique suitable for SARS-CoV-2 discovery because of its reliability and affordability.

As well as sensitivity, especially when compared to different analysis techniques like cell culture, antigen discovery, and serological approaches.

There are numerous reasons that negative test outcomes can develop as a result of an incorrect nasopharyngeal swab method.

One instance includes the numerous locations in between the opening of the nose and also the nasopharynx where the screening workers can experience resistance.

Commonly, a knowledgeable caregiver can acknowledge when the sampling swab has actually gotten to 9-10 centimetres into the nasal dental caries.

If the swab does not reach this depth, it has not accurately tasted liquid from the nasopharynx and can for that reason not adequately determine the existence of a disease within this location of the body.

For this reason, it is critical to assess whether employees receive proper education on how to accurately perform nasopharyngeal swab testing.

What is Viral Transport Media

Posted on 2022年3月14日2022年3月30日 by Dr. Lee

What is VTM?

VTM is the acronym for Viral Transport Media, which contains nutrients that carry the virus and keep it active so that the sample can reach the laboratory for testing.

VTM virus preservation solution is suitable for the collection, preservation and transportation of common virus samples.

Such as new coronavirus, influenza virus, hand, foot and mouth virus. It can collect throat swabs, nasal swabs or tissue samples from specific parts.

And the stored samples can be used for subsequent nucleic acid extraction or Purification and other clinical experiments.

Virus Transport Medium (VTM) Definition

The virus transport medium sampling tube is a complete set of centrifuge tubes for sampling and transporting viruses.

What is Viral Transport Media

Such as new coronavirus, influenza virus, hand, foot and mouth virus in the microbial sampling transport tube.

Also known as the specimen transport tube. commoditized products.

A nutrient is used to carry and maintain the viability of test specimens (viruses) for the identification and further processing of samples in laboratories.

Viral Transmission Media Principles (VTM)

Since there is no cellular structure. Viruses cannot replicate themselves, but instead, invade genes into host cells and replicate new viruses with the help of the latter’s replication system.

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 will be put into the transportation medium for storage and transportation.

Transportation medium composition and inspection principle:

1. The combination of various antibiotics has broad-spectrum antibacterial and antifungal effects.

2. As a protein stabilizer, bovine serum albumin (BSA) can form a protective film on the protein shell of the virus, making it difficult to decompose and ensuring the integrity of the virus

3. The neutral environment constructed by Hank’s buffer helps to increase the survival time and infection stability of the virus.

4. Phenol red is an acid-base indicator, the discoloration area is 6.6 (yellow)-8.0 (red), and it is red at 7.2-7.4.

Vtm Kit

The most stable pH value of the viral outer layer protein is 7.2-7.4, which is also the pH value range of Hank’s buffer. If contaminating molds or bacteria are not inhibited by antibiotics, they can multiply, releasing carbon dioxide and lowering the pH.

At this time, the appearance of the sampling solution will change from red to yellow.

Notes:

To produce an isotonic solution containing proteins to protect viral structures, antibiotics to control microbial contamination, and one or more buffers to control pH.
Use the concept of assays such as nucleic acid amplification assays (NaAt) to prepare viral delivery media while preventing samples such as drying.

Composition of viral transport media (VTM Kits)

There are mainly the following parts:

1. Sampling swab with disposable sterile plastic rod/rayon head;

2. Sterile sampling tube containing 3ml of virus maintenance solution;

In addition, there are additional parts such as a tongue depressor, a biosafety bag, etc.

Viral delivery media typically have protective protein components, antimicrobial agents to prevent the potential for contamination, and buffers to maintain the pH of the solution.

Some VTMs also have additional ions and minerals that help keep such samples viable.

How to use Virus Transfer Media?

Liquid transfer media are primarily used to transfer the swab or material from the collection swab into the media.

It facilitates the collection and transport of samples in areas where it is not available.

Precautions for use:

1. Before sampling, indicate the sample information on the label of the cryopreservation tube;

2. According to different experimental purposes, use sampling swabs to sample at the corresponding parts (the most commonly used are nasopharyngeal swabs, pharyngeal swabs are the oral swabs in the product);

3. Immediately after sampling, put the swab into the sampling tube containing the virus transport medium, break it at the breaking point, and tighten the tube cover;

4. The specific sampling methods are as follows:

a) Nasal swab: Gently insert the flocked swab head into the nasal palate, stay for a while and then slowly turn to exit. Swab the other nostril with another swab, immerse the swab head in the sampling solution, break it at the breaking point, and discard it.

b) Pharyngeal swab: Wipe bilateral pharyngeal tonsils and posterior pharyngeal wall with a flocked swab, and also immerse the swab head in the sampling solution and discard it.
