How to Use VTM Viral Transport Medium

  1. Peel the pack and use a swab for sampling in the nose or throat according to different 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.
  1. Insert swab into the storage tube and immerse the swab head into the medium
  2. Break shaft gently from the breakpoint, discard the tail and tighten the tube cap.
  3. Mark the relevant sample information on the label of the storage tube.
  4. Freshly collected clinical specimens should be delivered to the laboratory within 72 hours at 2℃- 8℃.
  5. Nucleic acid extractiondetection
  • 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
  • Suggested Temperature: 4°C -25°C.
  • Period of validity: 12 months.
  • Please refer to the outer case for the manufacture date and expiration date.


  • Samples collected with nasopharyngeal or oropharyngeal swabs should be transported at 2°C – 8°C and submitted for test as soon as possible.
  • After sampling, transport and storage time for specimen should be no longer than 72h.

Sample deterioration

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


  • Contamination during sampling process will affect the final results.
  • Sample storage at inappropriate temperature will affect the final results.
