When immigration DNA testing may be requested
An immigration or consular authority may request DNA evidence when documentary evidence of a claimed biological relationship is insufficient. DNA testing is generally used to address a specific relationship question, not as a substitute for the entire immigration process.
Frequently asked questions about immigration DNA testing
Key points
- Follow the requesting authority’s instructions exactly.
- Do not substitute self-collected samples for an official chain-of-custody collection.
- Requirements differ by destination country and agency.
Do not start as a peace-of-mind case
Immigration DNA cases should be arranged according to the instructions of the requesting authority. Self-collected samples and ordinary private reports may not be accepted.
Identity and chain of custody
Official cases typically require controlled identification of participants, witnessed collection, secure sample handling and documented chain of custody. The exact procedure depends on the country and agency involved.
Laboratory requirements
Some jurisdictions specify which laboratories may perform immigration relationship testing. For example, U.S. immigration relationship testing is tied to AABB-accredited relationship-testing facilities. Clients should follow the instructions issued for their own case rather than assuming that requirements are universal.
Overseas participants
When participants are in different countries, collection may need to be coordinated through an embassy, consulate, approved physician or authorized collection site. The laboratory and requesting authority should agree on the process before specimens are collected.
Before booking
Provide the laboratory with the immigration authority’s request letter or case instructions where available. Confirm the relationship to be tested, all participant names, locations and identification requirements.
