VTM sampling tube, also known as a virus sampling tube, is an essential tool in laboratory and clinical sampling processes. It is mainly used for detecting and sampling pathogenic microorganisms of infectious diseases, suitable for collecting various viruses, including influenza virus, COVID-19 virus, measles virus, etc. This article will provide a detailed introduction to the VTM sampling tube's usage, storage conditions, and precautions for use.
The VTM sampling tube has very broad applications, mainly used in the detection and sampling of influenza viruses (including general influenza, highly contagious, H1N1 influenza virus, etc.), hand-foot-mouth disease virus, COVID-19 virus, measles, rubella, and other types of viruses. Additionally, the VTM sampling tube is commonly used for sampling microorganisms such as mycoplasma, chlamydia, and ureaplasma. This versatile sampling tool can effectively collect virus samples and ensure the integrity and viability of the samples during transport.
The VTM sampling tube usually comes with disposable flocked swabs. These flocked swabs are soft and white, suitable for sampling from different sites without causing discomfort to the user. The swab is designed with a breakpoint that matches the length of the sampling tube, making the sampling process more convenient and aiding in the safe transport of specimens. This is why the VTM sampling tube is widely used in the field of virus detection and control.
The VTM sampling tube must be stored under specific conditions to maintain sample integrity. Under refrigerated conditions (2-8°C), viruses and related samples can be preserved and transported for 48 hours. For long-term storage, it is recommended to place the samples at -80°C or in a liquid nitrogen environment. These low-temperature conditions can effectively maintain the viability of the virus, slow down the rate of virus decomposition, and thereby increase the positive rate of virus isolation.
Strict control of storage conditions helps ensure the accuracy and reliability of samples during testing. One of the design purposes of the VTM sampling tube is to guarantee the stability of samples under different temperatures, making it an ideal choice for laboratory and clinical sampling.
First, the fluid inside the sampling tube is a culture medium for sample transport, and the sampling swab should not contact this fluid before sampling. Additionally, discarded sample collection fluids must be sterilized to ensure safety.
The VTM sampling tube is for in vitro diagnostic use only and cannot be used internally or externally on humans or animals. During use, if the transport medium of the sampling tube is found to be expired, discolored, or turbid, it should be immediately discontinued.
By following these precautions, the VTM sampling tube's safety and effectiveness during sampling and testing can be ensured.
In summary, the VTM sampling tube is an indispensable tool in the laboratory, not only being widely useful but also having strict storage conditions and usage requirements. Proper use of the VTM sampling tube can help ensure the integrity of samples and accuracy of test results, thereby playing a crucial role in virus detection and control.
