Virus Collection and Preservation system
Product name
Disposable Virus Specimen Collection Tube
Intended Use
Collection, preservation and transportation of human nasopharyngeal or oropharyngeal virus
samples.
Description
The system is mainly composed of storage tube, preservation medium, glass bead and
swabs. The medium is based on Hank's balanced salt solution. The system has a stable osmotic
pressure, which provides a appropriate transport and storage environment for swab samples. It can
maintain virus samples under prescribed conditions for routine nucleic acid extraction, genetic
testing and PCR testing, etc.

Sampling procedures
1. Peel the pack and use a swab for sampling in the nose or throat according to diffret sampling
requirements.
Nasopharyngeal swab: Gently insert the swab head into the nasal condyle of the nasal passage,
stay for a while and then slowly screw the swab to turn it out.
Oropharyngeal swab: Gently wipe the bilateral pharyngeal tonsils and posterior pharyngeal wall
with the swab.
2. Insert swab into the storage tube and immerse the swab head into the medium.
3. Break shaft gently from the breakpoint, discard the tail and tighten the tube cap.
4. Mark the relevant sample information on the label of the storage tube.
5. Freshly collected clinical specimens should be delivered to the laboratory within 72 hours at
2ºC-8ºC.
6. Nucleic acid extraction/detection:
For the Non-inactivated type,before extracting and detecting nucleic acids, the virus
inactivation and lysis must be performed with referring to the relevant standard steps of nucleic
acid extraction or the instruction manual of the extraction reagent to perform.
For the inactivated type, normal virus inactivation and lysis can still be performed as
required. And as the inactivated samples contain free viral nucleic acid, so the nucleic acid
extraction and detection operations can be directly done with referring to relevant standard steps
of nucleic acid extraction or the instruction manual of
