Maternity, siblingship, and grandparentage testing for estate, immigration, and family relationship matters. Legal and personal knowledge options available.
Schedule a ConsultationEach test serves a different purpose. Every appointment begins with a consultation — we confirm the correct test for your situation before anything is scheduled.
Maternity testing establishes whether a woman is the biological mother of a child. It is less commonly requested than paternity testing but serves an important role in specific legal and personal circumstances.
Siblingship testing determines the probability that two individuals share one or both biological parents. Results are expressed as a statistical probability — not a definitive yes or no — and the analysis is stronger when a parent is also tested.
Grandparentage testing establishes a biological relationship between a child and one or both of the alleged father's parents. It is used when the alleged father is unavailable, deceased, or unwilling to participate in paternity testing.
When a biological relationship must be established to determine inheritance rights — particularly when the connecting parent is deceased and direct paternity testing is not possible.
USCIS and immigration courts accept AABB-accredited DNA relationship testing as biological proof when documents are unavailable or insufficient. We coordinate testing that meets those requirements.
For individuals separated by adoption, migration, or family circumstance who are seeking biological confirmation of a family relationship for personal knowledge or official purposes.
Every relationship test follows the same clear process — from consultation through results delivery.
Contact us first. We confirm which test is appropriate for your situation, whether legal or personal knowledge testing is needed, and who needs to be tested. We answer every question before you commit.
We coordinate collection at your preferred location — home, office, or another private space — for all parties being tested. Weekend and after-hours availability upon request.
For legal testing, government-issued identification is verified and consent documentation is completed for all parties before collection begins. This becomes part of the chain-of-custody record.
Buccal cheek swabs are collected from all required parties. For some relationship tests, including both parents where possible strengthens the statistical result. We advise on this during consultation.
Samples are processed through our AABB-accredited laboratory partner. Relationship testing results include a probability index and statistical analysis specific to the test type.
Results are delivered securely by email or mail within 3–5 business days of sample receipt. Legal results include full chain-of-custody documentation. Results are never released by phone.
Every test begins with a consultation. Contact us first and we confirm the right test, the correct format, and exactly who needs to be included. No appointment is scheduled until everything is confirmed.
