Many people may have questions, we usually do new crown nucleic acid test sampling after the swab is put into a small tube to save, and then sent to the laboratory. So, what exactly is the liquid put in this small tube?
It turns out that the new crown nucleic acid test sampling tube is divided into inactivated and non-inactivated two types.
1, inactivation type preservation fluid, it belongs to the virus lysis type preservation fluid, the base fluid is a modified nucleic acid extraction lysis fluid, the composition of guanidine salt, Rnase inhibitor. It can be stored at room temperature.
It has the following advantages.
1) Saves the cost of virus sample preservation as well as transportation.
2) It contains high concentration of guanidine salt which can inactivate the virus efficiently and can effectively prevent secondary infection of the new crown nucleic acid rapid test operator.
3) Can be stored at room temperature for a relatively long time, saving the cost of preservation and transportation of virus samples.
2, non-inactivated preservation solution, which belongs to the virus maintenance fluid type preservation solution. The base fluid is a transport medium based modified fluid, the components are Hanks fluid base, gentamicin, fungal antibiotics, BSA (V), cryoprotectants, biological buffers and amino acids, etc.. It must be strictly low temperature.
The advantages:
1)Maintains the in vitro activity of the virus as well as the integrity of the antigen and nucleic acid.
2) In addition to being used for rapid detection of new crown nucleic acids, it can also be used for virus culture and isolation as well as antigen detection.
Now you all understand it, right?
So for different testing purposes and different Nucleic Acid Rapid Test laboratory conditions, it is necessary to sample different preservation solutions for the Nucleic Acid Rapid Test.
