Flocked Swabs For Sample Collection

Flocked Swabs For Sample Collection

Posted on by

The nucleic acid test (PCR TEST) uses a flocked swab instead of a cotton swab.

Flocking is a craft, not a material

　　 Flocking is not the fluff of any plant, but a very common fabric treatment process.

         Widely used in the textile industry, automobile manufacturing, printing industry, chemical industry and other fields.

　　 The flocking process means vertical fixing of some cut or milled short fibres to some kind of adhesive-coated surface. Short fibres are usually nylon, polyester, or other artificial fibers. The range of planting them is very wide, and surfaces such as cloth, plastic, wood, leather, paper, etc. can be flocked.

　　Flocking only needs three things, 1, short fibers; 2, adhesive, 3, some kind of surface

　　 Flocking is very common in everyone’s life, just usually without realizing it. For example, flocking fabrics can be found on clothes, curtains, carpets, and furniture. Usually, those surfaces that are fluffy and comfortable to the touch are brought by the flocking process.

　　 In addition to the decorative effect, the flocking technology has also been tried by scientists to make graphene lithium battery anode sheets; make special lipophilic and hydrophobic materials to absorb marine oil spills, etc.

The principle of flocking

　　 At present, the most commonly used flocking method is electrostatic flocking. After the fluff enters the high-voltage electric field, it contacts the negative electrode and is negatively charged. 

　　 Don’t worry if some fibers fall to the side and don’t stick to the side. After they touch the positive electrode side, the negative charges on the surface are completely neutralized, and they will fall to the negative end due to the force of the electrostatic electric field. Repeat the above movement until they are all stuck.

Flocked swabs for nucleic acid testing

　　 The flocking swabs used for nucleic acid detection are mostly “planted” with nylon short fibers. The reason for choosing flocked nylon over cotton swabs is the functional need for sampling.

Flocked swab

Flocked swab

Any material design is purposeful, and flocked swabs for nucleic acid detection need to meet the following characteristics:

　　  ② After the swab is put into the preservation solution, it has to “let go” to release the biological sample, and it cannot hold the sample firmly for a second or divide it. ③ It cannot react with biological samples and destroy the samples.

　　 Because cotton itself has superior hydrophilicity and adsorption, once it comes into contact with the sample, it is like the characters in Qiongyao play. In contrast, nylon flocked swabs are like a scumbag “can take it and put it down.

　　 Therefore, the collection and release volume of nylon flocking swabs is much larger than that of traditional winding cotton swabs. Experimental studies have shown that the collection and release volume of flocking swabs can reach 95% of the samples, while cotton swabs are only about 20%.

　　In fact, the ability of cotton swabs to grasp the sample is not bad, but after inserting the preservation solution, the flocked swab can quickly let go of the sample to be eluted, but the cotton swab will make the cells stuck in the fiber mass and cannot be separated.

　Otherwise, the nucleic acid will be degraded before the detection begins, and the correct result will definitely not be detected.

　　 Because of this, it is superfluous to worry that nylon is a synthetic fiber that is harmful to the human body. Flocked fibers have even been tried in regenerative medicine to help repair damaged bones and cartilage. By implanting the flocked fibrous scaffold, the properties of the extracellular matrix are modeled, allowing stem cells to adhere to it to proliferate and differentiate; and provide sufficient space for the newly synthesized matrix and capillaries to enter.

Flocked Swab Influenza

Flocked Swab Influenza | Comprehensive Flu Swab Test Guide

Flu Flocked Swab Influenza

Influenza refers to the common cold, which is an acute respiratory infectious disease caused by the influenza virus.

It is highly contagious and mainly spreads through droplets, such as coughing and sneezing. Influenza generally occurs in winter and spring.

The current influenza detection method is the rapid influenza antigen detection method, which detects “flux A” and “flu B” antigens.

Laboratory staff collect samples through throat swabs.

In fact, in inspection work, it is important to know the quality of the specimen in order to obtain accurate and reliable results.

Throat swab specimens: Professionals can avoid many false-negative influenza tests caused by improper specimen sampling.

The precautions for flu throat swabs are basically the same as those for nucleic acid detection throat swabs. Because the same part is sampled.

There are two types of flu throat swabs: nasopharyngeal swabs and oropharyngeal swabs.

What precautions should I take when taking a throat swab test for flu?

1. Oropharyngeal swab The collection method of the oropharyngeal swab is to let the subject open his mouth, then use a long pharyngeal swab to wipe the patient’s pharynx, bilateral frontal arches and tonsils, and take out the local secretions. Into the catheter of the throat swab and sent to the laboratory for testing.

2. Nasopharyngeal swabs The collection method of nasopharyngeal swabs is to use sterilized throat swabs to penetrate deep into the nasal cavity of the subject and reach the nasopharynx, and extract secretions and nasopharynx by rotating or wiping.

Epithelial cells put a section with secretions and epithelial cells into a sterile container and then carry out pathogenic detection.

Flu swab material

Swab options for flu testing include flocked swabs, cotton-tipped swabs, rayon tipped swabs, and foam-tipped swabs.

Cotton tip swab:

The original swab tips were all cotton, mainly based on their cleaning power and water absorption. Cotton swabs are very inexpensive and readily available, and are widely used in medical wound management after sterilization with ethylene oxide or autoclaving, as well as in forensic crime scene forensics. In the absence of alternatives, cotton swabs can be used in almost a variety of scenarios.

However, cotton-tipped swabs also have some problems. Due to the low release rate of cotton, natural material for samples, and some of the natural fatty acids in it can damage microorganisms, they are less and less used for sample collection.

Rayon head swab:

Rayon—a synthetic fiber made from wood pulp. Although classified as synthetic fiber, it is essentially a natural material. Compared to cotton, rayon is produced during the process of removing substances that may damage the sample or react with the sample during transportation and handling , so it is generally used for sampling for diagnostic testing.

Polyester Fiber Tip Swabs:

The head material of the polyester fiber swab is made of polyester long fiber winding, which was first introduced into the field of medical testing by DuPont. Polyester fibres are proven for microbial collection, rapid diagnostics, and PCR testing.

Polyester swabs have a high release rate but are more expensive than cotton and rayon swabs.

Foam tip swab:

Swabs made from medical-grade polyurethane are an excellent material for diagnostics, especially cell sampling. The swab tip of this swab is usually manufactured as a sheet with a surface hole count of 100ppi (holes per inch).

This material has good absorption of hydrophilic substances and poor absorption of hydrophobic substances. Used in some scenarios that require resistance to chemical corrosion. Also used for DNA and microbial sampling.

Flocked Swabs:

Flocking technology was first developed for cosmetic and industrial production. (Learn more)

After the flocking process was introduced into swab production. It replaced the traditional swab head, and the swab head was brought to a new level.

vtm swab

Due to the flocking process and the multi-branched polyester fibre material used, the flocked swabs have a very high absorption and release rate and are proven to be equally efficient for molecular sampling and absorption. Designated by some institutions for nucleic acid sampling as well as some research areas for genomic analysis.

The evolution of swabs is not limited to changes in materials. New demands in the fields of nursing, testing, and scientific research make swabs continue to evolve in multiple dimensions. The swab also not only acts as an applicator, but also acts as some transport medium.

Precautions include the following:

① Do not drink water before the throat swab test, at least 30 minutes in advance, because drinking water before the test 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 throat swab nucleic acid detection, do not drink water 15 to 30 minutes before the test to ensure that the throat swab has high accuracy.

②. For patients with good throat exposure, it is not recommended to take too long “ah~” sounds to reduce the risk of occupational exposure to the sampler.

③ To prevent vomiting, do not eat within two hours before the throat swab test.

④. Do not smoke, drink, or chew gum within half an hour before the throat swab test.

During the throat flocked swab sampling, the patient may have clinical symptoms such as nausea or nasopharyngeal discomfort, but the symptoms can subside quickly, so the patient should not be nervous and cooperate actively during the examination. At the same time, the subjects should not smoke, drink, or chew gum within half an hour before the sample collection.

If it is because of the throat swab the child, the parents must soothe the child’s emotions, communicate with the child patiently, and try not to move the child’s head as much as possible.

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

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

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

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

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

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

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

Discard damaged or contaminated swabs.

Specimen collection sterile flocked swab

Specimen collection sterile flocked swab

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

There are two main issues that netizens worry about:

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

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

Nasopharyngeal swab test

Nasopharyngeal swab test

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

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

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

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

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

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

Sterile

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

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

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

Flocked Sterile Swabs

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

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

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

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

For laboratory testing centres and hospitals.

What are the advantages of flocked Sterile swabs?

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

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

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

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

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

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):

When Taking An Oropharyngeal Swab

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.

					How Accurate Is The Nasal Swab
				

			
			
How Accurate Is The Nasal Swab


							

					Posted on   by  				

			
		


					

				


Swab test has methods such as nasal swab and pharyngeal swab.


Which is more accurate, nasal swab or pharyngeal swab?


Which of the two is more painful? If you want to know, let’s have a look.




Which is more accurate to detect a poke in the nose or a poke in the throat？


Theoretically, under the condition of standard operation, the results and accuracy of nasal swabs and pharyngeal swabs will be the same.


However, in the actual clinical work and the reagents for collecting samples, nasal swabs and pharyngeal swabs need to collect the secretions on the respiratory mucosa, which are irritating to some extent.


In particular, pharyngeal swabs are prone to nonstandard phenomena.


For example, without a tongue depressor, the pharynx of the subject is more sensitive and cannot collect qualified samples.


In addition, the throat swab needs the collector to open his mouth, which is easy to form aerosols and pollute the surrounding environment.


This will not ha ppen during the collection of nasal swabs.


In contrast, the results will be more accurate.


Nasopharyngeal swab and throat swab which is painful？


Depends on individual tolerance.


In the collection of nucleic acid sample detection samples through nasal swabs and throat swabs.


There will be a certain discomfort, but this discomfort is within the tolerable range.


However, compared with the two, nasal swabs may be less irritating to the mucous membranes, and the discomfort caused by standardized operations is less,


Collected through the nasal cavity, the public’s acceptance of them will be lower.


Can I do a swab test for a sore throat?


Yes.


Nucleic acid testing can also be performed during throat inflammation, which will not affect the results of the nucleic acid test.


It’s just that symptoms such as acute pharyngitis, acute tonsillitis, acute epiglottitis, etc., in the process of nucleic acid detection, have a certain degree of irritation to the mucous membranes of the throat, which can easily aggravate throat discomfort.


Recommended to inform the medical staff in advance before nucleic acid sampling.


Can I eat before the nucleic acid test


Avoid eating.


Avoid to eat 2 hours before the nucleic acid test, because when collecting nucleic acid samples, it is usually necessary to collect secretions from the throat or nasal cavity. Because the cotton swab will irritate the throat during nucleic acid test sampling, it can cause nausea and throat of the patient.


Symptoms such as discomfort, if you eat too much, it is easy to cause vomiting.


In addition, before the nucleic acid test, be careful not to smoke or drink alcohol, and it is best not to chew gum, otherwise the accuracy of the nucleic acid test may be affected.

EO sterilization refers to ethylene oxide sterilization.


Ethylene oxide (EO) is a highly efficient and broad-spectrum gaseous disinfectant.


It is by far the only most reliable and widely used sterilization method recognized worldwide. 


The nasal sampling flocked swabs included in the COVID-19 test kits are sterilized by EO or gamma-ray sterilization.


Rest assured, the swab is safe to use. Including ethane is a gas use commonly used to sterilize different types of medical equipment, flocked swabs for test kits. 


The time period for the entire process includes multiple heights and set-up phases, including post-swab removal of sterilized equipment to control ethane treatment. 


Allows monitoring of residues in contact with humans (EO amount has been according to ISO 10939-7:2008) ).


Our GMP Factory Flocked Swab Ethylene Oxide Covid Test
Our GMP Factory Flocked Swab Ethylene Oxide Covid Test


Ethylene Oxide Covid Test Sterile flocked Swab Principle


What is the principle of ethylene oxide sterilization (EO sterilization)? 


Ethylene oxide, also known as ethylene oxide, has the molecular formula C2H4O. 


The boiling point is 10.4°C, it is soluble in water, and the explosion limit in air is 3% to 100% (volume). 


Ethylene oxide is a highly volatile, explosive, flammable and toxic substance with ether smell when volatilized. It is a spectral sterilant. 


Ethylene oxide can effectively kill various microorganisms, including bacterial propagules, spores, viruses and fungal spores, and is a broad-spectrum high-efficiency sterilant.


Ethylene oxide molecule can produce alkylation reaction with a carboxyl group, amino group, sulfhydryl hydrogen group and hydrogen group on gene proteins necessary for metabolism in bacterial cells.


Instead of the unstable hydrogen atoms on the above groups, form a hydroxyethyl group. 


The rooting compound, because this compound destroys the necessary reactive groups in the important metabolic reactions of microorganisms, affects the action of bacterial enzymes, and causes the death of microorganisms.




Nasal swabs included in COVID-19 inspections are EO sterilized.


I heard that ethylene oxide sterilant is toxic and carcinogenic, but covid sterile swaps are all sterilized with ethylene oxide. 


Is it safe for us to use a covid swab? 


Is the risk of cancer caused by directly entering the respiratory tract greater? 


The words “Clean and Sterile EO” on the product packaging of sterile flocked swabs. At this point there’s a crowd that’s saying “


Specimen Collection Swab Ethylene Oxide In Swabs
Specimen Collection Swab Ethylene Oxide In Swabs


It’s completely dry here. 


There’s no result. But once you put it in a person’s nose, it’s wet. Once you inhale it, it’s going to kill us. It’s really killing people.” 


While it’s safe to say that direct exposure to ethylene oxide is actually linked to cancer (here), that doesn’t suggest that swabs sterilized with ethylene oxide definitely cause cancer cells. 


Ethylene oxide is a valuable disinfecting gas because it is very good at inactivating bacteria. 


It is used in factories in a very tightly controlled method to ensure that people working in manufacturing plants are not put at risk. 


It is a common chemical used to sterilize clinical tools and leave a minimal amount of product behind.


In conclusion, EO is a gas commonly used to sterilize clinical equipment such as COVID-19 nasal swab tests.


Ethylene oxide (ethylene oxide) is a highly efficient and broad-spectrum gaseous disinfectant.


It is by far the only most reliable and widely used sterilization method recognized worldwide. 


Although EO is carcinogenic, the use of this gas is safely regulated and has actually been used for decades.


Sterilization procedures are regulated to ensure minimal EO residues on medical tools.

What is Viral Transport Media


							

					Posted on   by  				

			
		


					

				
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
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.


Flocked Nasopharyngeal Meaning Swab Test Sample Collection Vtm Kit
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.
