3.[VTM use]
For sample collection, transportation and storage.
4.[viral transport medium tube test principle]
On the basis of Hank’s, potassium chloride, magnesium chloride and calcium chloride are added to provide necessary nutrient ions for pathogenic bacteria to make it more specific. The preservation time is longer, the integrity of pathogenic bacteria morphology is preserved to a greater extent, and the extraction rate of pathogenic bacteria is improved.
5. [structure composition ]
flocked swab and virus transport medium.(or universal transport medium).
6. [sample requirements]
the collected samples shall be sent to the laboratory within 48 hours at 2-8 ℃. If they cannot be sent to the laboratory within 48 hours, they shall be stored at – 70 ℃ or below. The samples shall be inoculated and separated as soon as possible after being sent to the laboratory.

universal transport medium and flocked swabs
8.[usage]
Firstly,before sampling, mark relevant information on the label of the sampling tube.
Secondly,use the corresponding sampling flocked cotton swab for sampling.
Then,after sampling, quickly put the cotton swab into the sampling tube, break the part higher than the sampling tube, and tighten the tube cover.
Finally,see the following for specific sampling methods.
a)Nasal swab: gently insert the sampling head into the nasopalatine part of the nasal catheter, stay for a moment, and then rotate it slowly to exit. Immerse the collected specimen into the liquid in the sampling tube, break the excess part and discard it, and tighten the sampling tube cover.
b) Pharyngeal swab: wipe bilateral pharyngeal tonsils and posterior pharyngeal wall with sampling head. Soak the collected specimen in the sampling solution, break the excess part, discard it, and tighten the sampling tube cover.
9.[precautions]
1. After collecting pathogenic bacteria samples, we should completely insert the disposable sampling flocked cotton swab into the preservation solution to retain pathogenic bacteria to the greatest extent.
2. The collected samples must be fresh and sent for examination in time to avoid the death of pathogenic bacteria.
3. Forbidden to use products with damaged packaging and expiration date to prevent pollution.
Note: For in vitro diagnosis. For virus sampling, transportation and storage.Including COVID-19.
Food can lead to serious events; It has certain irritation to eyes and skin. If it accidentally splashes into eyes, rinse with clean water.
