DENTAL FLOSS FOR DNA TESTING

Dental floss is advantageous for DNA testing as it is non invasive, can be used in the absence of an individual, is meant for a single user hence a single profile is guaranteed and has a relatively high success rate (~75%). However, it does not yield as much genetic material as standard samples like blood or buccal swabs and is prone to contamination.



How to Collect Dental Floss for DNA testing

1. Use a dry paper towel or gloves to pick up the floss(avoid contact with fingers).

2. Obtain the razor using a paper towel or gloves, avoid contact with fingers.

3. The floss should not contain moisture.

4. The floss should be recently used.

5. Place the sample in a paper envelope.

6. Label accordingly (name, collection date, relationship).

7. Send it to the laboratory for analysis.
