Legal DNA Testing for Paternity

dadcheck® are on the Ministry of Justice list of approved companies for performing maternity and paternity DNA tests for legal use. This means our legal DNA tests can be used to change details on a Birth Certificate, the Courts, CSA/CMS amongst other legal reasons.

For legal DNA tests we have to be in control of the sample collection and we undertake a protocol to identify the person providing the samples.  This will be undertaken by one of our registered samplers with the DNA test kit sent directly to our collectors. The samples then come directly back to our lab - maintaining what is often called a "chain of custody".

If you would like further information about a legally approved DNA test, including a no obligation quote, please call us on 0191 543 6334 or email: where our team are happy to help. Alternatively, please complete one of the forms below and email to us at the above email address:
