 Sampling for COVID-19 Testing: Introduction to Nasal Swabs, Pharyngeal Swabs, Nasopharyngeal Swabs

1. Material introduction:

1. Flocked swab: It is made of nylon fibre crowding modern technology, and also the front end is coated with nylon brief fibres repaired in a vertical manner so that there is no absorption hole in the whole tasting area of the tasting swab. As well as the sampling example, will certainly not be scattered as well as preserved in the fibers. Which promotes much faster and also a lot more efficient elution. Traditional cotton swabs can not entirely collect and also elute samples, while flocked swabs can elute 95% of examples. widely used.

2. Cotton Swab: The cotton bud is made from sterilized cotton wrapped around a wooden stick or a plastic pole. Because the all-natural product of cotton has a reduced release rate to the example, and also several of the natural fatty acids in it will harm microbes, the, even more, are much less as well as much less used for sample collection.

3. Rayon Head Swab: Rayon is a synthetic fiber made from wood pulp. Although categorized as an artificial fibre, it is basically a natural material. It is often the standard for diagnostic testing.

4.  Polyester Fibre Head Swab: The head product of the polyester fiber swab is made from polyester long fiber winding, which was very first presented in the field of medical screening by DuPont. Polyester fibres for microbial collection, rapid diagnostics, and also PCR screening. Swabs have a high launch price yet are extra expensive than cotton and also rayon swabs.

5. Foam Tip Swabs: Swabs made of medical quality polyurethane are superb materials for diagnosis, especially for cell sampling. This product has great absorption of hydrophilic substances and inadequate absorption of hydrophobic compounds. For some circumstances that need resistance to chemical rust, and also for DNA as well as microbial testing.

2. Introduction of sampling site:

Nasal Swab: Sampling of the nasal cavity.

Throat swab: Sampling of the throat area.

Nasopharyngeal swab: Sampling from the nasal cavity to the throat.

3. Safety factor and material:

Ordinary people can operate it. The new crown self-test products on the market generally use nasal swabs, and Foam Tip fibre heads are the first choice.

Throat swab: Professional operation is required, because the throat is more prone to injury, flocking swabs are the first choice.

Professionals must operate it, and it needs to be very careful from the nose to the throat. Generally, Westerners are easier to accept, while Orientals are less acceptable.

Nylon flocked swab

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.

COVID-19 Swab Test: What you should know

COVID-19 Swab Test: What You Should Know

Posted on by

An abrupt COVID-19 has brought flocking swabs, nasopharyngeal swabs, oropharyngeal swabs, nucleic acids, antigens, PCR and also other extremely professional terms right into the public eye. Today, CellMedical will certainly offer you preferred scientific research: those aspects of Coronavirus (COVID-19) screening.

What is a flocking swab, nasopharyngeal swab, or oropharyngeal swab?

When nations are executing a new round of nucleic acid screening, a report is spreading out in circles. The basic concept is “the cotton bud used for sampling have reagents on them, which are hazardous”. Some netizens also left a message to the CellMedical firm backstage, saying that after seeing the pertinent reports, the elderly at home shared that they did not want to take part in nucleic acid testing, and also really hoped that the younger generation would additionally attempt not to undertake nucleic acid testing as well as antigen testing.

“The covid test swab is not the same as the cotton swabs used in daily life, but it does not contain reagents, nor is it toxic”. ( Click here to learn more )

What is a flocked swab and why choose flocked oropharyngeal and nasopharyngeal swabs?

A flocked swab is used because it is more suitable for sampling and testing. The flocking swab(learn more) is made of nylon fiber flocking technology, and the front end is coated with nylon short fibers fixed in a vertical manner, so that there is no absorption hole in the entire collection area of ​​the collection swab. In this way, the collected sample is not dispersed and retained in the fiber, which facilitates faster and more efficient elution. Relevant data show that CellMedical flocked swabs can elute more than 95% of the sample collection volume; traditional cotton swabs, especially those made of absorbent cotton, cannot completely collect and elute samples.

Enlarged view of flocked swab

Enlarged view of flocked swab

Nasopharyngeal swabs – which require a swab inserted into the nose to collect samples from the back of the nose and throat – are the gold standard for collecting samples for diagnosis. But the process is technically difficult, often uncomfortable for patients, and requires personal protective equipment that may be in short supply.

Oropharyngeal swab – the oropharyngeal swab is a method of collecting oropharyngeal specimens by entering the sampling swab through the mouth – compared with a nasopharyngeal swab, it is less difficult, more acceptable to the public, and more universal. 

What exactly is PCR nucleic acid detection?

PCR (Polymerase Domino Effect, polymerase chain reaction) innovation is a wonderful creation, without the creation of PCR modern technology, there would be no modern-day molecular biology. Nucleic acid detection modern technology has likewise entirely transformed several techniques such as genetics, medication, and also forensics, allowing human beings to accomplish significant steps such as hereditary testing, viral infection identification, and also genetic testing.

"<yoastmark

Basically, PCR nucleic acid detection: To significantly magnify nucleic acid till it can be identified by equipment detection.  Yet if you increase the size of the nucleic acid, 1 ends up being 2, 2 comes to be 4, and also 4 ends up being 8. Consequently, PCR innovation is a method of amplifying nucleic acid.

After the covid-19 contaminates the human body, it will initially increase in the respiratory system. So it can be determined whether the body is infected by finding the viral nucleic acid in sputum and nasopharyngeal swabs. After a duration of infection, typically 7-10 days later, the body will certainly create specific antibodies versus the virus. IgM antibodies show up initially, adhered to by IgG antibodies. So immunological discovery approaches can identify these specific antibodies to identify whether the human body is carrying the virus.

Will the results from different nucleic acid testing institutions be consistent?

PCR nucleic acid detection has a strict standard procedure. It is the same SOP (Standard Operation Procedure). At the exact same time, all nucleic acid labs, regardless of dimension, must adhere to the same technological demands, and also the design and building of laboratories additionally have uniform specifications. Also, research laboratory screening staff have to go through standard technical training and also acquire a nationally identified task certification before they can work. It resembles KFC’s fried chicken all use the exact same dish. Whether it’s a fast window in the station, a sizable and comfortable dine-in in the town hall, or home delivery, you can constantly eat deep-fried chicken with the exact same preference, do not fret will certainly strike rumbling.

Therefore, no matter which institution we conduct nucleic acid testing, the outcomes need to coincide.

The collection of samplings from different components has different clinical importance. Along with the popular nasal swabs and throat swabs, sputum, blood as well as rectal swabs；

Nasal and throat swabs – upper respiratory tract specimens

Sputum – Lower Respiratory Tract Specimens ( Saliva Collection Kits )

Anal swab – digestive tract specimen

Blood – Antibody Test Specimen

What is the difference between nucleic acid testing and antibody testing?

The distinction between both is a positive nucleic acid shows the presence of viral nucleic acid in the sampling. Which suggests that the infected individual might be infectious. A favourable IgM antibody shows that the patient remains at the beginning of infection. IgG antibodies indicated that the patient had SARS-CoV-2. However, we were unable to determine whether it was transmissible. Compared with antibody detection, PCR nucleic acid discovery is much more sensitive and is additionally the “gold criterion” for laboratory detection.

Therefore, in recent cases, doctors discussed that the patient has symptoms of infection.

What factors may affect COVID-19 nucleic acid test results?

1. Viral load: In summary, when the viral lots are low. False negatives may occur.

2. The coronavirus may alter, which may further impact the accuracy of the test in the future.

3. Testing method: In the recently reported genuine tasting scene, several participants reported that the swab only revolved left and right in the mouth, and it really felt like it was only touching saliva.

However, did not reach the lingual and palatal arc, and the respondents did not have nausea and also reflexes. Sex-related security action, this type of tasting has a high possibility of not gathering exfoliated cells of the respiratory tract, so it is vulnerable to missed discovery, leading to false unfavourable results.

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.
Flocked Sterile Swabs

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

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.

　　The CellMedical virus sampling tube has a thickened and leak-proof design to ensure that the sample does not leak during transportation. It is a virus transport medium (VTM KITS) that complies with WHO regulations and biosafety regulations.

Flocked Swab Influenza

Flocked Swab Influenza | Comprehensive Flu Swab Test Guide

Posted on by

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.

"<yoastmark

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:

China Medical Nasal Foam Swab Factory And Manufacturers

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.

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.

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:

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.

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

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).

Flocked Nasopharyngeal Meaning Swab Test Sample Collection Vtm Kit

Test Sample Collection Vtm Kit

1. Sampling flocking swab: our company uses a nylon flocking swab (vtm swab). Because nylon flocking has no toxic effect on microorganisms and viruses and does not contain RNase and DNase.

It can maximize the collection and release of virus samples and ensure the accuracy of PCR test results.

The flocked swab rod: ABS material, with a unique breakpoint design.

Convenient to put into the sampling tube without contamination.

2. Virus sampling tube: The tube body and tube cover are made of polypropylene, which will not deform at high temperature and high pressure (121°C, 15min).  And will not become brittle at low temperatures (-196°C).

Resistant to static extrusion and dynamic impact.

The bottom cone design is resistant to centrifugation and shock.

They are packed with a transport medium (inactivated type, preserved type) for the release and preservation of samples to prevent leakage.

The sampling tube has built-in magnetic beads, which are convenient for elution and facilitate the release of more viruses into the virus transport medium.

Before the higher positive rate of PCR detection, the storage solution in the virus sampling tube was Hank’s solution.

Now, the virus sampling tube preservation solution has been upgraded to CellMedical virus preservation solution.

(that is, UTM, recommended by the World Health Organization and the National Influenza Center of China.)

Based on hank’s solution, BSA, HEPES, amino acids, glycerin and other ingredients. A high PCR test is positive.

Virus preservation solution includes non-inactivated virus transport medium and inactivated virus

In the non-inactivated COVID-19 sampling swab set, the components of the virus preservation solution usually include nutrients (such as salts, proteins, glucose), bacteriostatic agents, buffers, phenol red indicator, etc. required for the survival of the virus.

This virus preservation solution can maintain the activity of the virus to the greatest extent.

Not only for virus detection but also for virus culture and isolation.

In the inactivated new coronavirus sampling swab kit, the components of the virus preservation solution usually include buffers, virus lysing agents (usually guanidines), surfactants, etc.

This preservation solution can directly lyse the virus to release nucleic acid, which is convenient for subsequent nucleic acid detection.
