The DNA Twin Test will conclusively whether a set of twins are identical fraternal. Identical twins are genetically identical and will share exactly the same DNA profile whereas fraternal twins only share approximately 50% of their DNA in common. The full genetic report is included with every test.

A legal DNA test is a type of DNA test used to establish biological relationships for legal proceedings. A key requirement of these tests is that DNA samples must be collected by an impartial third party following a strict chain of custody protocol. This means the DNA samples are collected, documented, and transported in a way that ensures they remain untouched and unaltered until they reach the testing laboratory.

The results from legal DNA tests are frequently employed in legal proceedings such as child custody and support cases, inheritance disputes, immigration matters, and any other instances where there's a need to establish a biological relationship between individuals.

Frequently Asked Questions

During a DNA twin test, a buccal swab (mouth swab) is collected from each twin to obtain cells containing genetic information in the form of DNA (deoxyribonucleic acid). Most cells in our body contain a full set of genetic information unique to each individual, like a fingerprint.

In the laboratory, the DNA is extracted from the cells, and specific DNA regions are amplified through a process called PCR (polymerase chain reaction) for thorough examination. The DNA patterns of the twins are then compared to determine whether they are identical or fraternal twins with conclusive results.

The main difference lies in how the DNA sample is collected. For a legal DNA test, the sample collection process must be witnessed by an impartial third party following a strict chain of custody protocol, ensuring that the results are admissible in court. Home DNA tests don't require this, as they are often used for personal knowledge and not intended for legal proceedings. There is no difference in the accuracy between our home DNA tests and legal DNA tests.

We understand the urgency often associated with legal DNA testing. Once the samples are received by our lab, you can expect results within 1-2 business days.

To ensure DNA results are admissible in Canadian legal proceedings, the DNA samples must be collected and witnessed following a strict "chain-of-custody" protocol. We offer two convenient options to accommodate your needs:

Self-Arranged Collection: Our home legal option offers the flexibility of arranging your own independent professional, such as a physician, nurse, or notary, for sample collection and witnessing services. This individual must act impartially and cannot be related to you or have any personal or financial interest in the test's outcome.

Laboratory-Arranged Collection: With this option, our experienced laboratory staff will handle everything. They will directly communicate with all test participants to arrange appointments at a time that works for everyone. Our extensive network of sample collection locations spans across North America, ensuring there's always a suitable and convenient location within easy reach.

With our extensive network of collection centers across Canada, we can accommodate DNA sample collection from different locations. Please note, a $25 charge will apply if individuals in the same case are collected at different locations.

Legal DNA relationship atests employ strict identification and witnessing protocols to ensure the correct individuals are being tested. During DNA sample collection, each participant is obliged to present two forms of identification. One of these must be a photo ID, and they must also provide a recent photograph. In addition, fingerprints are taken as an additional measure of identification. An impartial third-party specimen collector, who has no connection to the case or the individuals involved, oversees and documents the entire process.

Yes, a DNA test can be safely performed on a baby. The DNA sample is collected via a non-invasive cheek swab, which is painless and safe for individuals of all ages.

In a paternity test, it is not required to test the mother in order to obtain a conclusive legal DNA test result. The test can be absolutely conclusive even with just the alleged father and child's samples. However, including the mother's DNA can help strengthen the results, but it is entirely optional

For other relationship tests like sibling or grandparentage tests, the inclusion of the mother's DNA may help in obtaining more precise results.

DNA paternity testing can be arranged online, by phone or by fax. Questions can be directed to the laboratory by email at or by phone at 1-855-284-6553. Our DNA advisors will be able to answer any questions you may have or to help you to schedule an appointment for testing.
