Note: The disposable nylon flocked swab tip should not touch anything other than the inside of the mouth to avoid contamination.

Hand-held disposable sampling swabs into the oral cavity side, in the inner mucosa, by moving up and down and scraping about 15 times, can increase the number of times according to the actual situation. The force is moderate to close to the mucous membrane of the inner wall of the oral cavity to ensure that the tip of the flocked swab can be dipped into the oral mucous membrane exfoliated cells at all places. Finally, follow the same method to collect DNA on the other side of the oral cavity lining.
  • 3. After the collection is completed, please put the disposable buccal swab into the sampling tube, push the swab rod to place the sampling tip into the preservation tube, tighten the cap and store it.
