Background
The virus sampling tube is an important sample collecting tool in the clinical diagnosis industry at present, and plays a great role in the nucleic acid diagnosis of the novel coronavirus in 2020.
Generally, a sampling tube is provided with a flocked swab, and 3ml of virus preservation solution is filled in the flocked swab. In the actual clinical collection process, the amount of mucus collected by the flocked swab is greatly different according to individual conditions, and the range of the mucus collected by the flocked swab can be 10-100 microliters, so that the sampled swab is broken and stored in 3ml of preservation solution, and the concentration of the sample is diluted by 10-30 times. It is also a matter of great significance how to properly reduce the dilution of mucus collected by a sampling swab by a virus preservation solution. The State administration organization of 8/17/2020 sets up the technical specification for the 10 in 1 mixed collection of new coronavirus nucleic acid, specifies the external dimension of the sampling tube, and requires that 6ml of preservation solution is subpackaged in the 10 in 1 mixed collection tube, which further increases the dilution condition of the collected sample.
