What Makes a Paternity Test Court-Admissible
A court-admissible paternity test depends entirely on an unbroken chain of custody—verified photo ID for each participant, documentation of every hand the sample passes through, and a sealed specimen shipped directly to an AABB-accredited laboratory. Our St. Mary's Road collection takes about 15 minutes.

Court-admissible paternity testing for Pima County families
-
When a result has to satisfy a judge, the science is the easy part—every accredited lab confirms biological fatherhood to better than 99.9 percent. For families with a case in Pima County Superior Court, that proof is the entire point: it's the reason your result gets entered as evidence instead of waved off. Families use these results for custody and child support proceedings, to add or correct a father's name on a birth certificate, and to settle estate or inheritance questions—anywhere a name has to be proven, not assumed.

When the court orders a DNA test, here's what changes
A court-ordered paternity test isn't a different swab — it's the same cheek collection held to a stricter standard.
If a judge has issued a court order for DNA testing, that order may name the parties, the lab requirements, and exactly where results are sent. Bring it in, and we collect precisely what it specifies. If you're testing ahead of a hearing without an order yet, that works too—a proactive, court-accepted paternity test often settles the question before it ever reaches a courtroom.
Who gets tested, and what to walk in with
-
You can walk in Monday through Friday, and same-day collection is available. A legal test only holds if everyone is documented, so come prepared. Every adult being tested needs valid photo identification: a driver's license, state ID, or passport. A child being tested doesn't need their ID, but bring their birth certificate, and the adult bringing them needs photo identification too.

Court-Admissible DNA Test FAQ
Do I need an attorney or a court order before I can book? Neither is required. Anyone can request a legal paternity test on their own, and many people do it before a case is even filed to get ahead of the question. If a court has already mandated testing, bring the order so we collect to its exact terms.
What if the other parent or child lives outside Tucson? That's common, and it doesn't break the test. We coordinate a chain-of-custody collection at an AABB-accredited site near them, and both samples route to the same lab — so distance between the parties never weakens a court ordered DNA test.
Do the father and child have to be tested at the same appointment? No. Both parties have to be collected under chain of custody, but they don't have to be in the room together. We can swab the father and the child at separate times—which helps in high-conflict situations where the parties would rather not meet.
