Many people may have questions, we usually do the new crown nucleic acid rapid test sampling, swab put into a small tube to save, and then sent to the laboratory to do the new crown nucleic acid rapid test. So, this small tube actually put in what liquid it?

It turns out that the new crown nucleic acid rapid test sampling tube is divided into two types containing guanidine salt and without guanidine salt.

1, inactivation type preservation solution, it belongs to the virus lysis type preservation solution, the base solution is a modified nucleic acid extraction lysis solution, the composition of guanidine salt, Rnase inhibitor. It can be stored at room temperature. Its advantages are:

1) It saves the cost of virus sample preservation and transportation.

2) It contains high concentration of guanidine salt, which can inactivate the virus efficiently and effectively prevent the secondary infection of the new crown nucleic acid rapid test operator.

3) It can be stored at room temperature for a relatively long time, which saves the cost of virus sample preservation and transportation.

2, non-inactivated preservation solution, which belongs to the virus maintenance fluid type preservation solution. The base fluid is a transport medium based on modified fluid, the components are Hanks fluid base, gentamicin, fungal antibiotics, BSA (V), cryoprotectants, biological buffers and amino acids, etc.. It must be strictly cryogenic.

The advantages are:

1) Maintaining the activity of the virus in vitro and 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, isolation and detection of antigens.

Now you all understand, 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
