How to prepare

Do not eat, drink, smoke, or chew gum for 30 minutes before a cheek-swab collection.
We will confirm participants and documentation before your visit.

For a legal case, each adult should bring a valid government-issued photo ID.
Bring the child's birth certificate or identification when applicable, with a parent or legal guardian present for minors.
Informational testing generally requires less documentation than legal chain-of-custody testing.
Bring any court, agency, or case paperwork connected with the request.
We'll confirm exactly what you need when we schedule.

Cashless payment by card, Klarna, or Affirm. All sales are final. Reschedules are honored for up to one year.
