Relationship testing
The program focuses on tests used to evaluate biological relationships, such as parent-child, sibling, grandparent, or other family relationships.
AABB accreditation applies specifically to relationship testing laboratories. It can be important when DNA evidence is requested for immigration, legal parentage, child support, custody, inheritance, citizenship, or another identity-sensitive matter.
This guide explains the difference between an informal at-home DNA test and a documented legal testing process, including laboratory selection, identity verification, professional sample collection, chain of custody, and local appointment planning.
AABB accredits facilities that perform relationship testing under defined quality and technical standards. The accreditation can be important for formal family-relationship cases, but it does not replace identity checks, documented sample handling, chain of custody, agency instructions, or local court requirements.
The most important distinction is scope. AABB relationship-testing accreditation applies to laboratories performing biological relationship testing. It should not be used as a general claim about every health, wellness, ancestry, or pet DNA test.
The program focuses on tests used to evaluate biological relationships, such as parent-child, sibling, grandparent, or other family relationships.
Accredited facilities are assessed against standards covering testing procedures, quality management, reporting, records, and other relationship-testing activities.
Accreditation can support the required laboratory pathway, but the complete case must still follow the procedures set by the requesting court, agency, attorney, or government department.
Accreditation lists can change. Confirm the facility in the current AABB-accredited relationship testing facility directory and ask for written confirmation of the laboratory handling your case.
A valid formal workflow depends on more than the laboratory name. The collection process must connect each sample to the correct participant and preserve a documented path from collection to testing.
The correct route depends on why the test is being requested. Confirm the test purpose before purchasing a kit or collecting any samples.
A government agency may suggest DNA evidence when other documents do not sufficiently establish a claimed biological relationship.
Courts, attorneys, or government departments may require a documented relationship test for a family-law or estate-related matter.
An at-home relationship test may be appropriate when the result is only for private information and no court or government use is expected.
Wait for the requesting government authority to recommend DNA testing and follow its written instructions. The U.S. Department of State instructs applicants to use an AABB-accredited laboratory and to work directly through the required laboratory process rather than independently purchasing an informal kit. Review the official DNA relationship testing procedures before beginning.
Both workflows may analyze cheek-swab samples, but the documentation and sample-control requirements are different.
| Comparison point | At-home relationship test | Legal or official relationship test |
|---|---|---|
| Primary purpose | Private knowledge and personal decision-making. | Potential submission to a court, agency, attorney, embassy, consulate, or other authorized body. |
| Sample collection | Participants generally collect their own cheek-swab samples. | Samples are generally collected by a neutral, qualified, or authorized collector. |
| Identity verification | Formal identity documentation is usually not part of the process. | Identification, photographs, signatures, and case documents may be recorded. |
| Chain of custody | No formal third-party chain of custody. | The sample route is documented from collection through laboratory receipt and reporting. |
| Laboratory requirement | Depends on the product and intended personal use. | An AABB-accredited relationship testing laboratory may be required by the requesting authority. |
| Result acceptance | Not designed for formal legal or government submission. | Acceptance depends on the complete process and the rules of the requesting authority or jurisdiction. |
| Best first step | Confirm that the result is only for personal knowledge. | Obtain written requirements before paying for testing or collecting samples. |
The exact order can vary, especially for international and government-requested cases. These steps provide a practical planning overview.
Identify the court, agency, attorney, or other organization that will receive or review the result.
Determine the required relationship, participants, documents, laboratory standard, and reporting route.
Schedule an appropriate collection appointment near each participant when self-collection is not permitted.
The collector verifies identity, obtains the samples, completes the records, and seals the package.
The laboratory reports through the authorized channel required for that particular case.
The accredited laboratory handling the analysis may be headquartered in another city or state while an approved sample collection appointment is arranged closer to each participant.
Availability can differ by ZIP code, participant age, relationship type, international shipping requirements, and case deadline.
A location page is a starting point, not confirmation that a particular collector, laboratory, or appointment is currently available.
Sharing the right details at the beginning reduces delays and helps prevent an informal product from being selected for a formal matter.
uDNA can provide general testing guidance but cannot decide whether evidence will be accepted, provide legal advice, override official instructions, or guarantee the outcome of a court, immigration, citizenship, or administrative case. Review the legal disclaimer when planning a formal test.
These resources explain sample collection, privacy, result timing, accuracy, and common testing questions.
Start with these practical answers, then confirm the specific requirements of the organization requesting your test.
No. AABB accreditation is specifically associated with relationship testing and is commonly relevant to formal legal or immigration workflows. Health, wellness, ancestry, and pet DNA tests follow different laboratory and quality requirements.
Not automatically. Laboratory accreditation may be one requirement, but acceptance can also depend on jurisdiction, court orders, participant identification, collector qualifications, chain-of-custody records, test type, and reporting procedures.
A self-collected at-home kit is generally intended for personal knowledge. Formal cases commonly require a neutral collector, identity documentation, sealed sample handling, and a documented chain of custody from collection to the laboratory.
Usually, a new collection is needed because the original self-collected samples did not follow the required identity-verification and chain-of-custody process. Confirm the intended use before collecting samples to avoid paying twice.
Begin with the current AABB directory and confirm the laboratory directly. The laboratory may arrange a collection appointment near you even when its headquarters is located in another city or state.
Wait until the appropriate government authority recommends DNA testing, carefully follow its written instructions, and use the required AABB-accredited laboratory process. Do not begin with an informal at-home kit.
Timing varies according to participant locations, appointment availability, document requirements, international shipping, laboratory processing, and the agency reporting route. Request a case-specific estimate before beginning.
Tell uDNA why the test is needed, where each participant is located, and whether a court, attorney, agency, embassy, consulate, or other organization provided instructions. The goal is to identify the appropriate next step before samples are collected.
