Court-Ordered Legal Test (Accredited Laboratory)
Neutral collector with photo ID verification.
Documented chain of custody from swab to report.
The only pathway courts generally accept.
Neutral collector with photo ID verification.
Documented chain of custody from swab to report.
The only pathway courts generally accept.
Laboratory reports directly to the requesting agency.
AABB accreditation is mandatory here, not optional.
At-home kits are rejected outright for this purpose.
Accredited laboratory, home collection.
Valid for your own information only.
Not admissible in court, by design.
Everything else in this category is detail hanging off that one question.
Chain of custody is the documented record that connects a named person to a specific sample. In practice it means a neutral collector, photo identification, photographs of the participants, and a report that records who collected what, when and where. That documentation is what makes a report admissible without requiring the laboratory staff to testify.
A home collection cannot produce it. Not because the laboratory is careless, but because there is no neutral party and no way to verify identity at the kitchen table.
Laboratories hold many kinds of accreditation. CLIA governs clinical diagnostic testing broadly. ISO 17025 is a general standard for testing laboratories. Neither includes the relationship-specific statistical formulas used to express a probability of parentage or kinship.
AABB accreditation is the standard that covers relationship testing specifically, which is why US courts and immigration authorities name it. Accredited laboratories typically analyze a panel of up to 28 markers and apply interpretation standards written for relationship questions. Sibling and grandparent tests need this even more than direct parentage tests, because the underlying statistics are more complex and more sensitive to a thin marker panel.
New York does not permit at-home paternity testing and requires collection at an approved facility. That is a legal requirement, not a recommendation. Several states also bar courts from ordering in-utero testing, and prenatal testing raises medical questions that a consumer purchase cannot address.
Before comparing products, confirm what your state permits for the type of test you want.
A DNA result is evidence. It is not a legal status. Establishing or disestablishing parentage runs through a court process, and a private test is generally not sufficient on its own even when the science is unambiguous. If a legal outcome matters, the test is one step and the process is the rest.
We score whether the laboratory is accredited and named, whether legal and personal pathways are clearly separated, whether state restrictions are disclosed before purchase, and what happens to samples afterward. A high score does not mean a result is admissible, and nothing here is legal advice.
These scores compare service pathways rather than consumer kits. A high score means the legal and personal routes are clearly separated and the accreditation is documented. It does not mean any pathway produces an admissible result without the required process.
This measures whether a pathway avoids implying diagnostic or medical value, and whether prenatal options are handled with clinical caution. It matters because relationship testing is sometimes bundled with health claims the test cannot support.
This measures whether a customer facing a disruptive result has a route to a qualified person. It matters because this is the highest-stakes emotional context in consumer genetics and support is usually absent.
This measures whether consent requirements are explained, including what happens when a party declines. It matters because consent disputes are routine in relationship testing and the rules differ between legal and personal pathways.
This measures whether the processing laboratory holds AABB accreditation for relationship testing and whether that laboratory is named. It matters because this is the standard courts and immigration authorities actually specify.
This measures whether a pathway states plainly that personal results are not court-admissible, rather than leaving the implication open. It matters because the cost of that misunderstanding lands on the customer in a courtroom.
This measures whether unrelated matching features are bundled into a relationship test and how they are described. It matters because bundling obscures what is being purchased.
This measures whether ancestry content sold alongside relationship testing is labelled as an estimate. It matters because the two products answer different questions and are often marketed together.
This measures what the policy commits to on sample destruction and record retention, including for legal cases where records may be held longer. It matters because samples tie to identifiable people, some of whom did not choose to be tested.
This measures the vendor's ownership history and the stability of its laboratory relationship. It matters because a reseller changing suppliers changes who holds the samples.
This measures whether relationship samples can enter research or be shared with third parties, and whether that is opt-in. It matters because consent in this context is often given under pressure.
This is the pathway that exists for proceedings. Collection happens in front of a neutral party, identity is verified with photo identification, and the laboratory reports with documentation that records who collected what, when and where. It is slower, more expensive and less convenient than an at-home kit, and it is the only route that produces a report a court will generally accept.
Anyone whose result will be read by a judge, an agency or an opposing party.
Anyone testing purely for personal knowledge.
No health claims. The strength is procedural: chain of custody is the product. Records may be retained longer than in personal testing, which is expected in a legal context but worth knowing.
Immigration testing has its own rules. The case is typically initiated by the agency, the laboratory must be AABB-accredited, and results are reported to the agency rather than handed to the applicant. An at-home result submitted in support of a petition is rejected, which is the most common and most expensive mistake in this category.
Petitioners whose case has reached the DNA evidence stage.
Anyone who has not yet been directed to test by the agency handling the case.
No health content. Governance is procedural and agency-driven, which means retention follows the case rather than a consumer account.
The personal pathway is the pragmatic choice when nothing formal is at stake. An accredited laboratory processes the samples, the statistics are the same as a legal test, and the result arrives faster and cheaper. The limitation is structural rather than scientific: without documented collection, nobody can prove whose sample was tested.
Buyers with no court, agency or immigration involvement.
Anyone who thinks they may need the result in a formal proceeding later.
No health claims. Deletion policies are usually documented, though samples and records may persist unless destruction is explicitly requested.
