Siblingship Testing

Sibling DNA testing, also known as siblingship testing, is a reliable way to determine whether two or more individuals share one or both biological parents.
By comparing the genetic profiles of two or more alleged siblings we can assess the likelihood that they share a biological parent.
This type of DNA test is commonly used when:
• A father or mother is unavailable for testing
• Families need answers for inheritance or estate matters
• Adoption or reunion cases are involved

For individuals who know they share one parent and are wondering if they share both parents, a full versus half siblingship test can be performed.
For individuals who are unsure if they share both parents and want to know if they are full siblings or unrelated, a full versus unrelated siblingship test can be performed.
Lastly, for individuals who may share one parent or be unrelated, a half versus unrelated siblingship test can be performed.

Generally, by increasing the number of relatives tested, the strength of the genetic evidence increases. Inclusion of additional related individuals may provide more robust statistical data in cases where the results come back inconclusive. If additional related individuals are not available for testing, extended marker testing is recommended. Additional fees apply.

A legal sibling DNA test is required when results must be used for official or legal purposes. This type of testing follows a strict chain-of-custody process and is accepted by Canadian courts and government agencies.
Common reasons clients request court-admissible siblingship testing include:
• Court proceedings or legal documentation is required
• Wills and Estate claims
• Citizenship and status applications
If you need a legal DNA test done, you can choose to come into one of our convenient testing locations across Canada or have a mobile unit sent to your home (available in select areas). During the collection process, the individuals tested are positively identified through photographs and government-issued identification. Certified DNA specialists collect the DNA by doing a simple and painless mouth swab from the inside of the cheek.
Once received at our laboratory, your results will be ready and sent via email within 5 to 7 business days, or for an additional $100.00 you can add a rush analysis which ensures your results are completed within 3 to 5 business days.

Private DNA sibling tests are treated the same as legal DNA tests in the laboratory, and they’re just as accurate. The difference is you can collect the DNA samples yourself in the comfort of your own home. You will receive your kit in the mail along with easy-to-follow instructions, collection envelopes, mouth swabs and a client ID form. We also include a self-addressed envelope so you can send back your samples for testing.
