Viral Transport Tube with Flocked Swab


Viral Transport Tube with Flocked Swab Introduction
The Viral Transport Tube with Flocked Swab (Virus Sampling Kit) is base on Hank’s balanced salt solution. The solution contains inorganic salts, amino acids, and protein-stable ingredients. The VTM has a stable osmotic pressure, which provides an appropriate transport and storage environment for swab samples. Specimens collected with nasopharyngeal or oropharynx swabs are sent to the laboratory for follow-up testing to determine whether been infected with some kinds of viruses.

Oropharynx swab: Wipe the bilateral pharyngeal tonsils and posterior pharyngeal wall with the swab, immerse the swab head in the sampling solution and discard the tail.
2. Insert swab into the sampling tube.
3. Break shaft slowly at the pre-scored line, and tighten the tube cap.
4. Mark the relevant sample information on the label of the sampling tube.
5. Put the collected sample tube in Biohazard Bag
6. Freshly collected clinical specimens should be delivered to the laboratory within 2 hours at 2°C~8°C.

Temperature: 5~25°C
Period of validity: 12 months
Please refer to the outer box for the manufacture date and expiration date.

Qualification of Specimen
Samples collected with nasopharyngeal or Oropharynx swabs should be transported at 2°C~8°C and submitted for inspection immediately.
After sampling, transport and storage time for specimen should be no longer than 48hrs.

Sample Deterioration
If the collected sampling solutions turns yellow or turbid, discard it and re-sample with a new piece of kit.

Contamination of sample during collection process will affect the final results.
Storing samples at inappropriate temperature will affect the final results.
