Paternity & DNA Testing — Legal (Court-Admissible) & Informational
Professional DNA collection for paternity, siblingship, grandparentage, maternity, immigration DNA, and postmortem DNA—scheduled at your convenience.
DNA Test Options
Paternity Testing
Confirm the biological relationship between an alleged father and child. Choose Legal for court/agency use or Informational for personal knowledge.
Siblingship
Determine whether individuals share one or both parents. Helpful when a parent is unavailable for testing.
Grandparentage / Avuncular
Establish a biological relationship through a grandparent or aunt/uncle when a parent is absent.
Call or email to discuss options and documentation.
Maternity
Confirm a biological relationship between a mother and child. Legal or informational collection available.
Contact us for availability.
Immigration DNA
DNA testing used by consulates or agencies to help document biological relationships in visa or citizenship matters. We guide you through compliant collection.
Postmortem DNA
When available, DNA samples may be collected or used following death for relationship clarification. Requires case review and documentation.
How Collection Works
- Schedule: choose Informational, Legal/Court, or Siblingship using the booking links.
- Check In: bring valid photo IDs (and any court/agency paperwork).
- Collect: buccal (cheek) swabs—quick, painless, and discreet.
- Chain-of-Custody: for Legal tests, IDs are verified and documentation is completed so results are court-admissible.
When to Choose Legal vs. Informational
Legal/Court-Ordered: required for court, child support, custody, name changes, or government agencies.
Informational: private peace-of-mind results not intended for court or legal use.
