Why use flocked swabs？

COVID-19 is New Coronavirus’s variant coronavirus, which can cause pneumonia after human infection. It belongs to an acute respiratory infectious disease, which is highly infectious and generally susceptible to people. It is easy to replicate in the upper respiratory tract of human body. In general, new crown nucleic acids are detected rapidly within 96 hours after infection. Testers can find viruses in the human upper respiratory tract. Experiments show that flocking swab can quickly elute > 95% of the original samples, and easily improve the detection sensitivity.

Application of sampling flocked swabs.

The upper respiratory tract of the human body includes the nasal cavity, pharynx and throat. That is to say, if a person is infected with COVID-19, he can extract the nucleic acid of the virus in the nasal cavity, pharynx and larynx in 96 hours. Therefore, we generally sample these locations when we carry out the rapid detection of new crown nucleic acid.

we distinguish swabs by different sampling positions. For nasal sampling, we become nasopharyngeal flocked swabs; For oral sampling, we become oropharyngeal flocked swabs.

What is the difference between nasopharyngeal swabs and oropharyngeal flocked swabs?

Nasopharyngeal swabs and oropharyngeal swabs differ in material hardness in addition to the differences in sampling sites. The nasopharyngeal swab is generally slender and soft, and can change its shape along the nasal cavity, which is convenient for the sampling personnel to probe into the upper respiratory tract along the nasal cavity. The oropharyngeal swab will be thick and hard.

In terms of comfort, there are also great differences between the two. Since gas exchange is often carried out in the nasal cavity, the swab shall be fully extended to the end of the nasal cavity during sampling to ensure that sufficient concentration of samples are collected.  This usually brings very uncomfortable feeling to the subject, and sometimes even leads to epistaxis.The oropharyngeal swab only needs to collect the pharyngeal sample, and only needs the person to open his mouth for collection. Although it occasionally causes a temporary feeling of nausea, the discomfort will not last too long.

There are also obvious differences between the two in drug loading. Studies have shown that in patients infected with the new crown virus, the amount of drug carried on the nasopharyngeal swab is significantly higher than that on the oropharyngeal swab. In other words, the detection amount of nasopharyngeal swabs is generally higher than that of oropharyngeal swabs.

In addition to nasopharyngeal flocked swabs and oropharyngeal swabs, there are anal swabs. As the name suggests, anal swab is a kind of test for patients with gastrointestinal symptoms. It can effectively improve the detection rate, but it is not widely used because of the inconvenience of sampling.

Attention

After sampling the flocking swab, we should immediately put the swab into the storage tube to avoid polluting the sample.  Then, the subsequent rapid detection process of new crown nucleic acid was carried out. No matter what kind of swab is used, the process of rapid detection of new crown nucleic acid is the same.  The rapid detection of new crown nucleic acid was completed in four independent areas of the laboratory, and the test results were obtained.

Cell medical (Dongguan) Co, Ltd.,Take you to know the virus sample preservation solution.

Virus sample preservation solution,also known as disposable virus sampling tube.When we first came into contact with this term, we must be very curious.

However,what is  DNA / RNA virus sampling tube？

First of all, virus sampling tube is a liquid that protects the tested substance of the virus by immersing the sampling swab virus sample in the sampling tube. Currently, it is mainly used for the collection, storage and transportation of common virus samples such as COVID-19, HFMV and so on. Medical workers can take tissue samples from the throat or specific areas using throat swabs and nasal flocked swabs. Samplers then store the samples for subsequent clinical trials such as nucleic acid extraction or purification. The virus and related samples can be stored at -70℃ or liquid nitrogen for a long time.

Usually,we divide the virus storage solution into two kinds. the non-inactivated virus storage solution and the inactivated virus sampling tube. The non inactivated type can protect viral proteins and nucleic acids. Maintain virus activity and facilitate culture and detection. Although the inactivated type can make the virus no longer have physiological activity, lose infectivity and pathogenicity, and have the ability to reproduce. Inactivate the virus, eliminate secondary infection,and protect the safety of transportation and testing personnel.

About inactivated sample preservation solution.

There may be a small partner who will question whether the inactivated type will inactivate the virus? How do you check it? Don’t worry, the purpose of using inactivated virus sampling tube is to lyse nucleic acid and detect nucleic acid by subsequent RT-PCR.

After extraction with most commercial kits, the quality of DNA or RNA obtained is good and the yield is high. So,it can complete various gene detection and analysis experiments, such as PCR or qPCR, and save transportation costs.

It is suitable for COVID-19, hfmv and other common virus samples.

About inactivated sample preservation solution.

  • The virus preserved in non inactivated virus sampling tube has better integrity and higher detection rate. Researchers use it for scientific research, including nucleic acid testing.
  • Cryogenic storage without freezing, does not destroy the virus shell, easy long-distance transportation;
  • Application:H1N1 influenza virus and any other Virus swab sampling;
  • The antibiotics in the preservation liquid can effectively prevent bacterial and fungal infection;
