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 for your own understanding only — a self-collected cheek swab, mailed in, private results. If the result needs to hold up in a Hays County courtroom or a child support case, the legal version is required, using a supervised, documented collection that can be relied on as evidence.
Informational Testing
A private, self-collected cheek swab, mailed in for fast results — right if you just want to know for yourself.

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 Texascourts & agencies
In Texas, a legal paternity test with a documented chain of custody may be used to establish paternity for child support, custody, or birth certificate purposes; informational tests are not accepted by Texas courts.
