Can using mouthwash immediately prior to getting DNA swab alter paternity results?

Using mouthwash immediately prior to getting a DNA swab should not alter paternity results. DNA paternity tests analyze the genetic material extracted from the cells collected during the swabbing process. Mouthwash typically contains antibacterial ingredients that may kill some cells within the sample, particularly bacterial, but the cells carrying the necessary genetic information for paternity testing should be abundant and unaffected by regular, non-detergent mouthwashes. In other words, the DNA test would still be valid and capable of determining the paternity.

To ensure accurate and conclusive paternity results, following the instructions provided by the DNA testing provider is crucial. This may include refraining from eating, drinking, or rinsing the mouth for a specified time beforehand. However, standard mouthwashes and toothpastes are generally not found to jeopardize the test accuracy.

If you have specific concerns or doubts, it is recommended to check with the testing provider before taking a DNA swab to get clarification and peace of mind regarding the testing process.
