What Is a Personal Paternity Test?

An informational paternity test in Mesa determines biological parentage privately through a cheek swab.

Results are for personal knowledge only and are not court-admissible.​

You can walk into our Mesa lab on E. University Drive and have our staff collect your sample in about 15 minutes or take a kit home and collect it yourself—whichever is more comfortable for you.

Because there's no chain of custody, the results are for your personal knowledge only and can't be used legally.

Your test results are available in 3-5 days or can be expedited.

Children Doing Science

How a Personal Paternity Test Works

Every paternity test answers one question: Is this man the biological father?

 

A cheek swab collects cells from inside the cheek, which carry a full set of DNA. A child inherits half of their DNA from each biological parent, so the lab compares genetic markers between the child's sample and the man's.

 

When enough markers match, paternity is confirmed with over 99.9% accuracy. In cases where they don't, he is ruled out with 100% certainty.

Every sample — whether collected at our lab or at home — is processed by the same AABB-accredited reference laboratory.

 

The science and accuracy are identical to a legal test; a personal test simply skips the ID verification and chain-of-custody, which is what keeps it private and more affordable.

Family Outdoors Together

Who Gets a Personal Paternity Test?

  • Personal confirmation: You simply want to know the truth for yourself, with no court case involved.

  • Parents and grandparents: Seeking answers without pursuing any legal action.

  • Partners and spouses: Looking for a private answer to a personal question.

  • Adult children: Confirming a biological father or family relationship.

  • Before legal testing: Getting the answer first, then deciding whether a formal legal test is needed.

What to Bring?

  • Testing in person? Simply come in. No ID or paperwork is required, since a personal test isn't used for legal purposes.

  • Using the at-home kit? Everything is included: cheek swabs for up to 3 people, step-by-step instructions, and a prepaid return label.

Personal Paternity Test FAQ

Do I need an appointment for a paternity test? No—you can walk in Monday through Friday or test at home on your own schedule.

How accurate is a personal paternity test? Very — it confirms paternity with over 99.9% accuracy and rules it out with 100% certainty. The science is identical to a legal test; only the collection process is different.

Can I use these results in court later? No. Because a personal test skips the ID check and chain-of-custody, a court won't accept it — you would need a separate legal test. If there's any chance you'll need results for court, start with the legal test.
