Virus Transport System (VTM-RT): A Capable Assistant in Clinical Diagnosis”

In the field of clinical diagnosis in modern medicine, the Virus Transport System (VTM-RT) is playing an indispensable role. Its numerous advantages have made it a capable assistant for accurately diagnosing viral infections.

VTM-RT has a wide range of applications in clinical diagnosis. For the diagnosis of respiratory viral infections, such as influenza virus and COVID-19, medical staff use the swabs in VTM-RT to collect nasopharyngeal swab samples from patients and then put them into sampling tubes containing preservation solutions. These samples can be quickly sent to the laboratory for nucleic acid testing or antigen testing. Since VTM-RT can effectively preserve the activity of viruses, even after the samples have been transported and stored for a certain period of time after collection, it is still possible to accurately detect the presence or absence of viruses and the specific types of viruses. This is crucial for timely detecting patients’ infection status and taking targeted treatment measures. For example, during the influenza outbreak season, rapid and accurate diagnosis enables patients to receive antiviral treatment as early as possible, alleviating symptoms and reducing the risk of complications.

Its characteristics and advantages are significant. Firstly, the sample preservation solution of VTM-RT has been carefully developed and has good buffering capacity. It can maintain a stable pH value and provide a suitable living environment for viruses, effectively preventing the degradation and inactivation of viruses. This means that even if the test is carried out several hours or even days after sample collection, the nucleic acid and protein structures of the viruses can still remain relatively intact, greatly improving the accuracy and reliability of the test. Secondly, the sampling tubes of this system are made of high-quality materials and have excellent sealing properties, avoiding the risk of sample leakage and also preventing contamination by external microorganisms, ensuring the purity of the samples.

When using VTM-RT, there are also some precautions. Medical staff should strictly follow the operating procedures when sampling to ensure that sufficient virus samples are collected and avoid false negative results due to insufficient sampling. For example, when collecting nasopharyngeal swabs, the swabs should be inserted to the appropriate position and rotated a certain number of times to obtain more epithelial cells and viruses. After sample collection, the swabs should be immediately put into the sampling tubes, and it should be ensured that the sampling tubes are sealed properly. During transportation, the samples should be stored in the specified low-temperature environment to avoid high temperature and severe vibration so as to maintain the activity of the viruses.

With its crucial application in clinical diagnosis, excellent characteristics, and standardized usage requirements, VTM-RT has become an important tool for diagnosing viral infections in modern medicine, providing strong support for ensuring patients’ health and timely treatment and vigorously promoting the development of clinical diagnosis technology.
