Viral transport medium is a protective liquid medium added to the virus sampling tube to protect the samples after nasopharyngeal swab sampling and is usually called virus preservation solution in China.
Usually, in nucleic acid testing (PCR swab test), we cannot perform nucleic acid PCR directly at the sample collection site.
We need to add virus preservation solution (VTM) to the samples collected by swab for transfer check.

What is a virus?
Viruses are microorganisms whose structure is very simple.
There is no way to complete the process of self-replication.
They need the help of host cells and the nutrition of the host to complete virus replication.
The virus can infect humans as well as many other animals.
Influenza viruses such as common infectious diseases are usually RNA viruses.
There are many common viruses that cause human infection, which can cause respiratory diseases, such as cold virus, influenza virus, HIV and influenza A virus.
Since it has no cellular structure of its own, the virus itself cannot replicate.
But invades the gene into the host cell and replicates the new virus with the help of the latter’s replication system.
In conclusion, viruses are diverse and can cause damage to multiple parts of the body. “
After the virus sample is collected, in order to maintain the activity of the virus sample and prolong the survival time of the virus in the sample, the sampling swab ( flocking swab ) will be put into the preservation solution ( viral transport media ) for preservation and transportation.
What is the viral transport medium used for?
PCR test
The inactivated viral transport medium can perform protein denaturation on fresh clinical virus specimens to inactivate the virus. Prevent secondary infection and ensure the safety of transportation and testing personnel. The inactivated samples can be used with a variety of virus extraction kits.
The nucleic acid extraction instrument can quickly extract nucleic acids.
At the same time, with the respiratory pathogen PCR detection kit (VTM Kits) to achieve rapid detection. The specificity and sensitivity are not affected.
Virus preservation solution has many functions:
1. The operation is simple, and the liquid contains ingredients that can denature proteins, thereby inactivating the virus;
2. Contains inhibitors to protect the stability of viral nucleic acid to a greater extent and greatly improve the nucleic acid extraction rate;
3. Stored at room temperature for 12 months before sampling.
The airtightness is good, which is convenient for storage and transportation and saves transportation costs.
Cell medical (Dongguan) Co., Ltd.
Viral transport media include inactivated and non-inactivated viral transport media.
Contains Hank‘s Liquid, Potassium Chloride, Magnesium Chloride, Calcium Chloride, BSA, etc. The combination of various antibiotics has antibacterial and antifungal effects. Bovine serum albumin (BSA), as a protein stabilizer, can form a protective film on the protein shell of the virus. Making it difficult to decompose and ensuring the integrity of the virus; Hank’s buffer The neutral environment constructed by the agent helps to increase the survival time and infection stability of the virus.

Nasopharyngeal Swab
Inactivated and non-inactivated virus preservation solutions: usually used for the collection and transportation of clinical influenza, avian influenza, hand, foot and mouth virus, measles and other virus specimens, as well as specimens such as mycoplasma, ureaplasma, chlamydia, etc.
