VTM oral swabs

VTM oral swabs have the following specific applications:
Nucleic acid testing: used to collect oral mucosal epithelial cells for nucleic acid testing of viruses, bacteria and other pathogens, such as new coronavirus nucleic acid testing.
Genetic research: to collect samples for genetic analysis and related research.
Forensic identification: obtain oral cell samples in forensic identification.

VTM oral swab mainly has the following specific applications:

1. Nucleic acid testing: It is used to collect oral mucosal epithelial cells for nucleic acid testing of pathogens such as viruses and bacteria, such as COVID-19 nucleic acid testing.
2. Genetic research: Collect samples for genetic analysis and related research.
3. Forensic identification: Obtain oral cell samples in forensic identification.

The features of VTM oral swab are as follows:

Material and design

• Excellent swab material: The head of the VTM oral swab usually adopts a nylon flocked material, which is non-toxic to cells and viruses and does not contain RNase, which can maximize the collection and release of specimens and ensure the probability of obtaining a positive result in nucleic acid testing and other experiments.
• Unique plastic sticker design: The plastic sticker design on the swab rod is unique, easy to break, and there is no debris residue when broken, which is convenient for operation and avoids the contamination of samples or experiments caused by debris generated during the break.

Sample collection and release

• Efficient collection: The nylon flocked head is like a soft brush, and the capillary movement between the fibers forms a strong hydraulic pressure, which can effectively capture samples such as oral mucosal epithelial cells, greatly improving the collection efficiency, and even a small amount of samples can be collected well.
• Easy to elute: Its hydrophobic characteristics ensure that the sample can be quickly and completely eluted, ensuring that the collected sample can be fully released into the preservation solution for subsequent accurate detection and analysis.

Preservation solution performance

• Two types to choose from: The virus preservation solution equipped with the VTM oral swab is generally divided into non-inactivated type and inactivated type. The non-inactivated preservation solution contains ingredients such as nutrients, bacteriostatic agents, buffers, phenol red indicators, etc. required for the survival of the virus, which can maximize the retention of the virus’s activity, and can be used not only for virus detection but also for virus culture and isolation; the inactivated preservation solution contains ingredients such as buffers, virus lysing agents, and surfactants, which can directly lyse the virus to release nucleic acids for convenient subsequent nucleic acid detection.
• Efficiently preserve samples: The formula of the preservation solution has been optimized through a large number of experiments to maintain the stability of the virus or nucleic acid in the sample, reduce its degradation during storage and transportation, and ensure the accuracy of the test results. For example, under appropriate storage conditions, it can keep the virus or nucleic acid in the sample active or intact for a long time, providing a reliable sample for subsequent detection.

Safety and stability

• High biosafety: The entire VTM oral swab kit, including the swab, preservation solution, and sampling tube, etc., has undergone strict sterilization treatment, and is packaged in internationally common sterilized paper-plastic packaging to ensure sterility and prevent the sample from being contaminated and avoid the user from contacting harmful pathogens.
• Good transportation stability: The sampling tube is usually made of medical-grade PP material, and the tube body and tube cap are specially designed to withstand high temperature and high pressure, low temperature, etc., and are not easy to deform and embrittle, and can withstand static extrusion and dynamic impact, and the conical design at the bottom enables it to withstand centrifugation and oscillation, and has good sealing performance to prevent sample leakage and ensure the stability and safety of the sample during transportation.

Operational convenience

• Simple to use: The use of VTM oral swab is simple and easy to understand. Medical staff or relevant testing personnel only need to follow the standardized operation steps to easily complete the work of sample collection, preservation, and transportation, reducing the difficulty of operation and human error.
• Clear identification: There is enough space on the sampling tube for marking relevant information about the sample, such as the patient’s name, sample type, collection time, etc., to facilitate the identification and management of the sample and avoid confusion.
