Oral Rinse Collection

To get the best specimen possible, we need to collect cells from the inside of the cheeks and gums. Make sure to rinse the saline solution vigorously FROM ONE SIDE OF YOUR MOUTH TO THE OTHER, concentrating on cheek-to-cheek swishing.

Please do not brush your teeth or use mouthwash for at least 2 hours prior to collection, and do not eat, drink, smoke or chew gum for at least 30 minutes prior to collection.
