Virus sampling tube manufacturers will take you to understand the two types of virus sampling tube
When a specimen is collected using a virus sampling tube, the conventional specimen cannot be immediately tested by PCR. It is often necessary to transport the swab sample with the sample. The virus itself can quickly lyse outside the body and interfere with subsequent testing.
A virus protection solution must be added for transport. The following virus sampling tube manufacturers will take you through the two types of virus sampling tubes: inactivated and non-inactivated.
For different testing purposes, different virus sampling tubes are required.
The two virus sampling tubes widely used at the time each have their own characteristics. In order to meet different testing requirements and different virus testing laboratory conditions, it is usually necessary to sample different virus sampling tubes.
Inactivated virus sampling tubes: mainly virus lysis preservation solution modified from nucleic acid extraction lysate. During sampling, high concentration of guanidine salts can effectively inactivate the virus and effectively prevent the operator from re-infecting the virus. And it can be stored at room temperature for a relatively long time, thus saving the cost of virus sample preservation and transportation.
Non-Inactivated Virus Sampling Tubes: It is primarily based on an improved virus binder preservation solution for transport media. Non-inactivated virus sampling tubes maintain virus activity and the integrity of antigens and nucleic acids in vitro, maintain the protein shell of the virus and are less susceptible to disintegration, and maintain the originality of the virus sample to a large extent. In addition to nucleic acid extraction and detection, the storage solution can be used for virus culture, isolation and antigen detection. However, long-term storage after sampling requires strict cryogenic conditions.
As can be seen, different virus sampling tubes need to be selected depending on the conditions. However, it should be noted that whether inactivated or defectively inactivated, the virus sampling tubes must be thoroughly inactivated and disinfected prior to sampling to ensure that the tubes are free of other microorganisms, which could lead to virus breakdown. Other or other effects after sampling lead to false detection. The use of poor quality collection tools or preservation solutions after swab sampling will affect subsequent test results and even lead to false positives for misdiagnosis. Therefore, it is necessary to choose a virus sampling tube manufacturer.
Virus sampling tube belongs to the medical device products, domestic manufacturers are mostly in accordance with a class of products for the record, according to the second class product registration of enterprises are very few, recently in order to meet the urgent needs of Wuhan and other places, there are many enterprises are to take the "emergency channel" to apply for a record of a permit.
Virus sampling tube consists of a sampling swab, virus preservation solution and packaging. Due to the lack of uniform national standards or industry standards, the products of various manufacturers vary greatly.
