Most people don't realize there are two different tests until they start looking — and they serve very different purposes.
A private at-home test is right if you're testing purely for your own peace of mind — a cheek swab, mailed in, private results. If the result needs to matter in a Multnomah County courtroom or a child support proceeding, the legal version is required instead, using a supervised, chain-of-custody collection that a court can rely on without dispute.
Informational Testing
A private, self-collected cheek swab, mailed in for fast results — right if you just want to know for yourself.
- Collect at home, on your own time
- Results in a few days

Legal Testing
A supervised, chain-of-custody collection — required if the result needs to hold up in custody, support, or immigration matters.
- Photo ID verified at collection
- Witnessed, documented process
- Accepted by Oregoncourts & agencies
In Oregon, at-home DNA test results are not accepted as legal proof of paternity; courts and child support agencies require a chain-of-custody genetic test performed at an accredited facility, with witnessed collection and identity verification, before parentage can be legally established.
