DNA Testing Services

Our personal information, at-home DNA paternity test kits are dispatched within the UK by Royal Mail 1st class.

From the time we receive your properly consented DNA samples (day zero), our standard paternity test takes 2 working days or you can pay a little bit extra for fast next working day results!

That DNA Company: Extended Services


Do you require a DNA test for legal purposes? (An accredited test)

This is for changing the name on a birth certificate at the Registrars office, family court proceedings, inheritance disputes, liaison with either the Child Support Agency (CSA) or the immigration authorities. As this is a different level of service, please click here to contact the laboratory by e-mail.


Do you require a DNA test to determine other relationships?

As well as testing for paternity (proof of fatherhood), we can also test for other biological relationships such as sibling (full, half or unrelated), grandparent and aunts/uncles. Again, this is a different service and you will need to discuss your case with a member of our team. Please click here to e-mail our laboratory.
