The role of transport medium

The transport medium is a medium used for the collection, transportation and preservation of pathogenic bacteria or microbial specimens, including liquid and solid types.

Principle of Inspection

Different formulas used in different types of transport media can improve and increase the viability of the corresponding microorganisms in the specimens, so as to facilitate the short-term preservation of the specimens during transportation.

Main ingredients

The main ingredients are formulate with solvents such as sodium chloride,

potassium dihydrogen phosphate, dipotassium hydrogen phosphate, agar, and calcium chloride.


  1. Not only can the morphology, structure and number of almost all cells be preserve, but the specimens can be preserve at room temperature for up to 6 months.
  2. The remaining cells can not only directly test for HPV, DNA, and Chlamydia, but also for gonorrhea and immunochemical tissue tests.
  3. Eliminate most germs and microbial activity within 15 minutes. Avoid possible harm to medical staff.


  1. Before sampling, mark the relevant sample information on the label of the sampling tube.
  2. Sampling with the corresponding sampling swab.
  3. After sampling, quickly put the swab into the sampling tube.
  4. Break the swab at the breaking point of the swab and discard the tail.
  5. Tighten the tube cover tightly. Then put the sampling tube containing the sample into the biosafety bag and send it for inspection in time.
