How a Buccal Swab Works

A buccal swab is a simple, non-invasive procedure used to collect DNA from the inside of your cheek. The swab is rubbed gently against the inside of your cheek to collect cells that contain your unique DNA.

How to Prepare for a Buccal Swab:

• Rinse Your Mouth: About 30 minutes before your appointment, rinse your mouth with water to remove any food particles.
• Avoid Eating or Drinking: Do not eat, drink, or smoke at least 30 minutes before the test to ensure the sample is not contaminated.
• No Oral Care Products: Avoid using mouthwash, brushing your teeth, or chewing gum right before the swab to avoid any interference with the sample.

By following these simple steps, you’ll help ensure that the buccal swab is effective and provides accurate results.
