Virus sampling tubes usually consist of a swab and/or cup and a tube with a sterilizing solution.
They are used for sample collection, transport and storage. Virus sampling tube principle of action: after sterilization of the sampling tube, you can add components that stabilize the virus, such as Hank's alkaline solution, which maintains the activity of the virus in a wide range of temperatures and reduces the rate of Virus decomposition, increasing the rate of positive virus isolation.
1, virus sampling tubes should be collected immediately at a low temperature of 2-8°C and should be sent for examination as soon as possible. Virus samples can be stored at 2-8°C for 48 hours. Long-term storage should be stored at -20°C, -70°C or -196°C below low temperature, where the H1N1 virus particles are sensitive to -20°C and need to be stored below -20°C. If the sample is not transported immediately after low temperature or stored at the specified temperature, the positive rate of virus isolation will be affected later.
2, Virus sampling tubes are only used to collect virus samples. The antibiotics contained in the sampling solution can inhibit bacteria, so sampling bacterial samples is strictly prohibited.
3, sampling tube is strictly prohibited to directly contact the patient being collected, and it is strictly prohibited to wet the swab before sampling the patient.
4, When collecting virus samples, the sampling procedure should be strictly followed to ensure accurate sampling position, uniform sampling intensity and applicability, otherwise it will affect the positive rate of virus isolation.
5, Do not use after the expiration date, otherwise the product packaging will be damaged.
6, Samples should be tested in a laboratory that meets safety standards.
7, Virus sampling tubes can cause the spread of bacteria and mold when transported at unsuitable temperatures after sampling, and the antibiotics in the previous sampling solution will completely inhibit the microorganisms in the sample.
