  • It is suggested that you do a couple vigorous mouth rinses with water (and/or mouthwash) around 10-20 minutes before collecting the DNA sample from your mouth. This will reduce bacterial contamination, help eliminate other potential contaminants, and improve the quality of results from DNA sequencing.
  • When providing a saliva sample: you may want to consider trying to gently loosen up some cheek cells with your tongue, in order to get a higher DNA content in the saliva.
