In the kit...

The DNA testing kit contains;

  • A folder with information about Cellmark and the DNA testing kit
  • Clear instructions about how to take the DNA samples

  • A sample declaration form for each person, requiring a signature to provide consent
  • A tamperproof, prepaid return envelope

Taking a sample...

Court approved DNA test

While a home DNA test can provide peace of mind, if you need to use your DNA testing results as part of a legal process, for example as part of a child custody case or a maintenance settlement, then you will need to arrange a ‘Court Approved DNA test’. This will mean having DNA samples taken and your identity verified by an independent sampler.

As a member of the Ministry of Justice's list of accredited bodies, Cellmark is accredited to carry out parentage tests directed by the civil courts in England and Wales under section 20 of the Family Law Reform Act 1969.

  Great service - thank you

Thank you very much for your prompt reply and additional details. This is all useful information and it confirms what we thought, but couldn't prove. My father has found two half sisters he didn't know he had, and he has seen a picture of his mother for the first time. It only took 79 years to find her.

Please pass my thanks to your laboratory, my dad will now celebrate his 80th birthday with his sisters and learn more about the mother he never knew.
