Sample analysis can be unsuccessful if there is insufficient DNA collected on the swab, or if the sample has become contaminated. In the event of a sample failing analysis, you will be notified and a replacement test kit will be sent for the collection process to be repeated.
When submitting a replacement sample, we recommend the following tips to ensure the highest chance of success:
1. Do not eat, drink, smoke, chew gum, brush your teeth, or use mouthwash for at least an hour prior to providing your sample.
2. Swab your cheek for the full recommended 1 minute.
3. Make sure the swab is securely sealed in the tube along with the silica capsule.
