Disposable Virus Sampling Tube (Vtm)

1 tube with 3ml media
1 nasal swab
1 biohazard bag

With the recurrence of asymptomatic, nucleic acid testing cannot be stopped for a moment. This is not only a protection for everyone, but also a protection for yourself. Speaking of nucleic acid testing, we have to bring up our virus sampling tube again. Its choice also plays a key role.
Why use a virus sampling tube?
Virus detection is different from conventional biochemical detection. The virus itself is a simple microorganism that must be parasitic in living cells. After sampling, the virus leaves the host cell, and its protein shell and nucleic acid will be quickly degraded in the sampling tube, so the nucleic acid During the test, it is impossible to determine whether the initially collected sample contains the virus, and it is easy to cause false negatives.
What are the requirements for an excellent virus sampling tube?
1. In terms of sample effectiveness: The non-inactivated virus preservation solution must maintain the activity of the pathogen's infectious agent. Preferably, it can preserve the activity of the virus at room temperature. The inactivated virus preservation solution needs to inactivate the virus but maintain the nucleic acid of the virus to meet the time from sample sampling to laboratory testing. It is necessary to limit and prevent the reproduction of symbiotic microorganisms to ensure the reliability of diagnostic tests.
2. In terms of safety: Because the virus sampling tubes are basically all infectious substances, and some are highly pathogenic infectious substances, the requirements for packaging containers are very strict, and they need to meet safety and ensure that liquids do not leak during transportation. .
So what is the virus preservation solution? Under what circumstances do I need to use a virus preservation solution?
The virus preservation solution is a protective liquid medium added to the virus sampling tube to protect the sample after the nasopharyngeal swab is sampled. Normally, nucleic acid PCR cannot be directly performed at the sample collection site during nucleic acid detection. If the sample collected by the swab needs to be transferred and transported, it is necessary to add a virus preservation solution.
Why is the virus preservation solution divided into inactivated and non-inactivated?
After the virus samples are collected, there is usually no way to test in time at the sample sampling site, so the collected virus swab samples need to be transported, and the virus itself will be quickly lysed outside the body and affect subsequent testing, so when storing and transporting , You need to add a virus preservation solution. For different detection purposes, you need to use different virus preservation solutions and different virus detection experimental conditions, so it is divided into two types of preservation solutions, inactivated and non-inactivated.
There are no other microorganisms, causing the virus to decompose after sampling or other influences causing false detections.

CE,ISO 13485
Novel Coronavirus (COVID-19) Nucleic Acid Detection Kit (RT-PCR) is used for nucleic acid detection of the ORF1ab sequence and N gene of the Novel Coronavirus (SARS-CoV-2) in nasopharyngeal swab, oropharyngeal swab, sputum and other specimens.
The primer and probe sets in this kit are designed for the detection of the conserved sequences of SARS-CoV-2 (ORF1ab and N gene). The kit also contains an Internal Control (human RNase P gene) that is used to assess specimen quality and avoid a false negative result. Real-Time PCR technology utilizes polymerase chain reaction (PCR) for the amplification of specific target sequences and target specific probes for the detection of the amplified RNA. The probes are labelled with fluorescent reporter and quencher dyes.

4.Procedure
1.Open the package, take out the single-use virus sampling tube, and mark relevant information;
2.Take the matching swab and place it on the area where the specimen needs to be collected (such as the nasal cavity, oral cavity, throat, vagina, urethra, etc.), and gently wipe it more than 15 times to collect the sample.
3.Open the cover of the sampling tube, insert the swab of the collected sample into the sampling tube and break it from the fragile part, insert the swab head into the preservation solution in time, and tighten the tube cap;
4.Place the tightened virus sampling tube properly, and then transport to the inspection department for inspection within 48 hours.
