Virus Transport System (VTM-RT) is a professional system used for clinical specimen collection, storage, and transportation. The following is a detailed introduction to it:

Basic composition

It usually consists of a sampling swab and a screw-cap tube containing virus transport medium (VTM).

Specific applications

• Clinical diagnosis: It is widely used in the diagnosis of various viral infectious diseases, such as COVID-19, monkeypox virus, influenza virus, hand, foot, and mouth disease virus, measles virus, etc., and is also suitable for the detection of pathogens such as chlamydia, mycoplasma, and ureaplasma.
• Large-scale screening: It can efficiently handle a large number of samples during large-scale virus detection in institutions such as hospitals, centers for disease control and prevention, and testing laboratories, ensuring the orderly progress of detection work.

Characteristics

• Maintaining virus activity and nucleic acid integrity: Its unique formulation design can effectively maintain the activity of the virus and the integrity of the nucleic acid to ensure that the sample will not be damaged or deteriorated due to external environmental factors during transportation, providing a reliable sample for subsequent detection.
• Good compatibility: It has a high degree of compatibility with various nucleic acid extraction kits and detection reagents, providing more options for the laboratory, which can be flexibly used according to actual needs.
• High safety: It is packaged aseptically and contains ingredients such as bacteriostatic agents to prevent the sample from being contaminated by microorganisms such as bacteria and fungi during collection and transportation, and also avoids the risk of operators being infected by infectious samples.
• Convenient to use: The equipped sampling swab has a humanized design, such as a flocked nylon swab head with good adsorption and release properties, which can conveniently and quickly collect enough samples, and the swab has a formed breakpoint, which is convenient to break and put into the transport tube.

Precautions

• Sample collection: Strictly follow the operating procedures for sample collection to ensure that the collection site is accurate, the sample quantity is sufficient, and avoid sample contamination or cross-infection. After collection, the swab should be placed in the transport tube as soon as possible and the tube cap screwed tightly.
• Transport and storage: After sample collection, it should be transported and stored within the specified temperature and time. Generally, it is recommended to be transported refrigerated at 2-8°C or with wet ice and delivered to the testing laboratory for testing as soon as possible.
• Validity period and quality inspection: Before use, the validity period and appearance of the transport system should be checked. If phenomena such as expired transport medium, discolored, turbid, or leaked liquid are found, it is prohibited from being used.

Advantages

• High detection accuracy: It can quickly and accurately detect the presence of the virus with high sensitivity and specificity, reducing the occurrence probability of false positives and false negatives, and improving the reliability of the detection results, providing strong support for the early diagnosis of diseases.
• Efficient and convenient: It provides a one-stop solution for sample collection, storage, and transportation, simplifying the operation process, improving work efficiency, and saving time and labor costs.
• Reliable quality: The production process strictly follows the quality management system, such as ISO13485, to ensure the stable and reliable product quality, meeting relevant standards and regulatory requirements.
