Home DNA Test Kits in Canada

DNA paternity testing is 100% accurate when done properly.

In addition to having qualified analysts or scientists conducting the testing procedures and reporting, all of TheDNALAB’s legally-documented tests include identity verification with a strict Chain of Custody and inspection of all received packages to ensure proper sample handling.

To date, none of our Legal DNA results have been successfully challenged or overturned in a Court of Law.

No. Testing the mother typically yields a higher probability of paternity (thus is scientifically recommended), but it is not mandatory. The test may be conclusive without obtaining a sample from the mother; however, it will require more analysis to provide conclusive results.

Yes. DNA testing to confirm paternity can be conducted in the absence of a biological sample from the father. When an individual is deceased or unavailable for testing, it may be possible to use other biological family members – for example, the biological mother and one or both paternal grandparents.

Non-standard or ‘Reference’ samples can also be used. For example, blood or tissue samples (sent directly to our laboratory from either the Coroner or Medical Examiner’s Office). Personal items can also be submitted as reference samples for tests that are for curiosity. (Personal items typically would not meet our protocols to qualify for a Legal DNA test).

Yes. DNA testing to confirm maternity can be conducted in the absence of a biological sample from the alleged mother. When an individual is deceased or unavailable for testing, it may be possible to use other biological family members – for example, the biological father and one or both maternal grandparents.

Non-standard or ‘Reference’ samples can also be used. For example, blood or tissue samples (sent directly to our laboratory from either the Coroner or Medical Examiner’s Office).

Yes. However, it is imperative that we be advised of this possibility prior to testing. For example, if the two possible fathers are brothers or father and son, they will share a high percentage of the same DNA and could both be included as the biological father of the tested child within the accurate range of a 99.95% probability result.

Results for a standard DNA test are reported in 3 to 5 business days from receipt of all required samples at our laboratory. If you require results faster than that, it is possible to turn around results within 24 hours. Please call us for details.
