Welcome to Cellmark, the Home of DNA testing.

Cellmark is the UK's most recommended DNA testing service and we've been providing a confidential, conclusive & court approved DNA paternity testing service for 20 years.   We are accredited by the Ministry of Justice as a body that may carry out parentage tests (otherwise called DNA Testing or Paternity Testing) as directed by the civil courts in England and Wales under section 20 of the Family Law Reform Act 1969.

We can offer advice, take DNA testing registrations over the phone, or online, and we can manage the whole sampling and testing process - download our "Making the right choices" guide today.
