Request 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.
Relationship testing may be requested when an agency, institution, or other authority requires documented proof of a biological relationship. We confirm the testing and documentation requirements before scheduling.
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.

We coordinate collection at an appropriate private location based on the circumstances of the case and the parties being tested. Weekend and after-hours appointments are available upon request.
For legal testing, the required identity verification, consent documentation, and chain-of-custody paperwork are completed before collection begins.
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.
Legal relationship testing is processed through an AABB-accredited relationship-testing laboratory. Results include the laboratory's statistical analysis appropriate to the relationship being evaluated.
Results are delivered according to the laboratory and case requirements within the applicable turnaround window. Legal results include the applicable chain-of-custody and laboratory documentation.
