What is a virus sampling swab kit?

swab test swab kits

swab test swab kits

The virus sampling swab set is a virus sampling and transfer product for virus nucleic acid detection.

Including a sampling swab (Specimen Collection Swab), a sampling tube and a virus preservation solution.

It can be used for nasopharyngeal and oropharyngeal covid-19 sampling swab sets, the virus preservation solution is also called virus transport medium (Viral Transport Media), referred to as VTM.

According to the composition and function of virus preservation solution.

Including non-inactivated type and inactivated type.

Non-inactivated virus sampling swab kits

In the non-inactivated new coronavirus sampling swab kit. 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 and not only for virus detection but also for virus culture and isolation.

Inactivated virus sampling swab kits

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 we need to pay attention to is that whether it is an inactivated type or a non-inactivated type, the virus sampling tube is sterile.

There are no other microorganisms that could cause false detections due to viral breakdown or other influences after sampling.

After flocked swab sampling, if a collection tool or preservation solution of poor quality is used, it will affect the subsequent test results and even cause false positives for misdiagnosis.

Different types of preservation solutions have their advantages and disadvantages according to different situations.

Recommended using a virus preservation solution of good quality.

Nasopharyngeal Swab Sample (Nasal Swab)

The nasopharyngeal swab: A specimen collection tool used to collect cell samples from the nasopharynx (above the throat).

When a patient develops an upper respiratory tract infection, doctors can use the collected samples to detect it, especially when the patient still has a fever.

In the experiment, technicians can detect common sources of infection, including potential pathogens such as the new crown and swine flu.

How is the COVID-19 nasal swab test performed?

Such tests can be uncomfortable for patients, but can quickly identify serious respiratory illnesses, especially those that require isolation or infection prevention measures to protect other patients.

Doctors can use cell cultures to determine the type of current infection. Factory-produced nasopharyngeal swabs cannot use natural substances such as cotton, as they may contain some impurities that will affect the detection.

Nasopharyngeal Swab materials

The nasopharyngeal swabs produced and sold by Cell Medical Company are flocked materials. Learn more about flocked swabs.

flocked swab

flocked swab

CellMedical flocked swabs are famous for their stable and reliable performance and excellent absorption and elution ability.

In general, a caregiver can place a sealed package (safety bag) next to the patient, and the caregiver places a sample container next to the patient, which contains a culture medium that maintains cellular and microbial viability for evaluation. This is the viral transport medium.

Laboratory technicians can detect the source of infection through nasopharyngeal swabs, and they should wear gloves and masks when collecting nasopharyngeal swabs.

Face protection is an effective measure to prevent patients from contracting respiratory diseases.

Nasopharyngeal swab collection

When taking the sample, gently insert the swab into the nose by hand, pushing it all the way to the nasopharynx. Patients often experience discomfort, convulsions, or spasms; for this, they sometimes need to suppress this response by leaning their heads against a wall or pillow.

When the nasopharyngeal swab is fully in, the caregiver can briefly swirl to collect the cell mixture, remove it, and place it in the specimen collection container. (Virus sampling tube)

After the sampler obtains the sample, he should immediately send it to the laboratory for PCR testing.

Waiting or not storing at low temperature may kill microorganisms that may be present in the sample, resulting in false-negative test results.

Patients usually get results within a day or two.

Inspection is capable of scanning for many common microorganisms.

When infectious diseases appear in epidemic areas, nasopharyngeal swabs and other microorganisms can be labelled to detect new crowns, swine flu and other microorganisms.

The doctor can try the test results to guide the patient’s treatment.

They can also help epidemiologists track the movement of diseases in the community, which is very useful for controlling disease outbreaks.

How to Choose a Correct Virus transport medium for COVID-19 Testing


Disposable virus sampling tube
Disposable virus sampling tube




At present, the form of New Coronavirus is still very serious.


As the first step of covid-19 detection, the importance of sample collection and preservation is beyond doubt.


The influencing factor is sample collection; If there is a problem with the collected sample, the result is invalid regardless of the subsequent treatment.


Selecting appropriate virus transport media and collecting flocking swabs can improve the efficiency of new crown detection.


Almost all virus preservation solutions on the market contain non inactivated viruses directly, resulting in high infection risk for sampling, transportation and testing personnel.


Therefore, the front line of epidemic prevention needs to be able to inactivate virus samples directly.


At 37 ° C, we compared the preservation effects of cell medical (Dongguan) preservation solution containing guanidine hydrochloride and guanidine isothiocyanate with that without guanidine salt on avian coronavirus.


After 1-7 days of storage, under the same condition of 37 ℃, the preservation rate of virus nucleic acid was basically maintained at 100% when it was preserved with cell medical (Dongguan) preservation solution;


·Use virus preservation solution that can protect the sample from high temperature inactivation.


The results showed that high temperature inactivation had no significant effect on the integrity of coronavirus nucleic acid when coronavirus nucleic acid samples were preserved with high temperature inactivator.


The virus preservation solution developed by Cell medical (Dongguan) company is divided into inactivated and non inactivated. Different preservation solutions can be selected according to different test requirements and test conditions. If you have any questions or needs, please call us. Choosing cell medical (Dongguan) virus transport media solution in China is your right choice.


Furan compounds (guanidine isothiocyanate or guanidine hydrochloride, etc.) are typical protein denaturants.


They are often used to extract cell lysis in nucleic acid and inactivate virus. However, the furamethoxam component does not have the ability to work at room temperature.


Because the ability to preserve viral nucleic acid is easy to lead to sample degradation, it is not suitable for preserving new coronavirus samples. Therefore, it is strongly recommended that you choose the preservation solution without guanidine salt.


To this end, we call on the majority of medical personnel to select non inactivated virus transport media if they take samples for the purpose of nucleic acid detection and do not need to culture live viruses.


Vtm Swab | Virus Transport Medium with Sampling Swab
Vtm Swab | Virus Transport Medium with Sampling Swab


Use a virus medium that inactivates the virus.


At present, covid-19 detection is mainly to detect viral RNA, which needs to divide the virus.


Therefore, as long as the integrity and stability of virus nucleic acid can be guaranteed, there is no need to preserve live virus.


Therefore, in the current situation of fighting COVID-19, it is ideal to inactivate the virus while collecting samples. Some manufacturers have also introduced inactivated transport medium, but its inactivating component is guanidine salt.


The results showed that the salt forming component storage solution had insufficient storage capacity for viral nucleic acid at room temperature, which was easy to cause sample degradation.


Therefore, we recommend the use of virus preservation solution containing non guanidine protein denaturants.


The volume of solution in the sampling tube should be appropriate.


① When sampling each sample separately, we recommend that you select a virus sampling tube containing 1ml storage solution to ensure the correct storage capacity. It can not only meet the downstream needs of nucleic acid extraction and detection. Compare with 3ml storage solution. Triple the virus concentration!


② For large-scale preliminary screening and mixing test, we should choose to put the samples of 3-5 people into the sampling tube.

·Use a virus preservation solution that can transport and preserve samples at room temperature.


If the delivery temperature does not meet the standard, the viral nucleic acid may degrade, resulting in a “false negative” test result!


On the contrary, if cell medical uses a virus storage solution that can transport and stably store virus nucleic acid at room temperature.


We solved the problem of sample transportation and improved the accuracy of test results.


·Use virus preservation solution that can protect the sample from high temperature inactivation.


However, the research reports of Beijing Center for Disease Control and prevention in the Journal of “clinical chemistry” and Beijing Preventive Medicine Research Center show that high temperature inactivation can lead to the degradation of virus nucleic acid, thus reducing the detection rate of virus nucleic acid. Therefore, The false negative rate of New Coronavirus nucleic acid detection is high.
