The main structure and performance of the virus sampling tube: usually composed of swabs and/or cups and test tubes filled with antiseptic solution. Provide non-sterile.
Scope of application: for sample collection, transportation and storage, etc.
Principle of action: After disinfecting the sampling tube, you can add components that stabilize the virus, such as Hank's alkaline solution, to maintain the activity of the virus in a wide temperature range, reduce the speed of virus decomposition, and increase the positive rate of the virus .


Contraindications, precautions, warnings, suggestive instructions:
1. The virus sampling tube should be sent for inspection as soon as possible, and should be collected immediately at a low temperature of 2-8°C. The virus sample can be placed at 2-8°C for 48 hours. Long-term storage should be stored at a low temperature of -20°C, below -70°C or -196°C. Among them, H1N1 virus particles are sensitive to -20°C and need to be stored below -20°C. If they are not transported at low temperature immediately after sampling, or stored at a specified temperature, it will affect the positive rate of virus isolation at a later stage.
2. The sampling tube is only used to sample virus samples. Strictly prohibit the sampling of bacterial samples. The antibiotic contained in the sampling solution itself has a blocking effect on bacteria.
3. It is forbidden for the virus sampling tube to directly contact the patient being collected, and it is forbidden to sample the patient after the swab is wet.
4. When collecting virus samples, the sampling procedures should be strictly followed to ensure that the sampling location is accurate and the sampling intensity is uniform and appropriate, otherwise it will affect the positive rate of virus isolation.
5. The product must not be used after the expiration date, otherwise the product packaging will be damaged.
6. When testing samples, it should be performed in a laboratory that meets the standards.
7. The sampling tube after sampling is transported at an inappropriate temperature, which will cause the spread of bacteria and mold, and the antibiotics in the previous sampling solution will completely block the microorganisms in the sample.
