DetailsA Maternity DNA Test is used to determine who is the genetic Mother of a Child or Children. A standard Maternity Test analyzes DNA specimens from the Father (if available), the Child, and the Alleged Mother. A simple mouth swab is all that is needed to get a DNA sample from each of the tested parties. Paternity Testing Corporation will continue testing your samples until we reach a minimum Maternity Index (MI) of 10,000, or 99.99% for both Peace-of-Mind (At-Home) Test, or a Legal (Chain-of-Custody) Tests.

In order for a DNA test to be used for legal purposes, certain processes and requirements must be met.
  1. The DNA samples must be collected by a certified, independent third party.
    • This sample collector must also be able to testify in court that they collected samples correctly.
  2. The DNA samples must follow a strict Chain of Custody procedure, from the point of sample collection, all the way to testing at our laboratory.
    • It is also important that the people being tested are never left alone with their samples.
  3. The people being tested have had their identities verified.
    • To prevent someone providing samples on behalf of someone else, we must verify the people being tested are who they say they are.
    • This calls for additional paperwork, ID, photographs, thumbprints, contact details, and more.
  • Nothing. The actual testing / analysis of DNA for a Legal (Chain-of-Custody) Test and a Peace-of-Mind (PoM) Test is identical. Both undergo the same rigorous testing, both are guaranteed at a minimum of 99.99%, and both are issued with notarized result reports.
  • The difference is that Legal DNA Tests have had DNA samples collected by a certified independent third party and have followed chain-of-custody. Furthermore, the people being tested must have their identity verified and documented.
  • However, in a PoM Test, you can collect your own samples and send them to us for testing. Therefore, a PoM Test cannot be used for immigration, custody or any other legal purposes because the above three criteria have not been met.
When you go to your sample collection appointment, be sure to bring:
  • Photo ID
  • Birth Certificate for children
At your appointment, we will:
  • Take copies of your Photo ID / Birth Certificate.
  • Get thumbprints (or for babies we sometimes get footprints) of all people being tested.
  • Take a 'mug shot' of all people being tested.
  • Fill out consent forms and other paperwork.
If you want to use your results in Thailand, the answer is “yes”. But you can make this decision once you know the result of your test. 
  • We are one of the very few foreign laboratories that can issue results that are accepted in Thailand, as well as abroad.
  • If you were to take paternity test with the Thai Police Hospital, your results do not need to be authenticated. However, it usually a minimum of four months to get your results with the Thai Police Hospital, and your results won’t be accepted outside of Thailand. There are currently no AABB-accredited DNA laboratories based in Thailand.
