1, expiration date of sample: non-inactivated virus preservation solution must keep the activity of pathogen infection factor, and zui can preserve the activity of virus at room temperature. Inactivating virus preservation solution needs to inactivate the virus but keep the nucleic acid of the virus to meet the time from sample sampling to laboratory testing. It is necessary to limit and prevent the reproduction of living microorganisms and ensure the reliability of diagnostic tests.
2. Safety: Because the virus sampling tubes are basically filled with infectious substances, and some of them are highly pathogenic infectious substances, the requirements for packaging containers are very strict, and it is necessary to meet the safety and ensure that the liquid does not leak during transportation.
