How a Buccal Swab Works:

A buccal swab is a quick, painless procedure that collects DNA by gently rubbing the inside of your cheek.

Preparation Steps:

• Rinse Your Mouth: 30 minutes before your appointment.
• Avoid Eating, Drinking, or Smoking: At least 30 minutes before the test.
• No Oral Care Products: Avoid mouthwash, toothpaste, or gum prior to the swab.

Following these steps ensures accurate and reliable results.

Legal Notice for Texas Residents:

• For minors or those unable to consent, a parent, legal guardian, or court authorization is required.
• Texas law mandates consent from the person being tested or their legal representative, especially in family law or paternity cases.
