Who we are

thatDNAcompany® is a brand which belongs to Complement Genomics Ltd, one of the most established and trusted DNA testing companies in the UK.

About our vision

Performing DNA tests since 2000, we are one of the most long-standing and experienced testing laboratories and our vision has always been one of enabling people to access complex genetic information, to answer questions of parentage.

thatDNAcompany® is an online value brand designed for you to access DNA tests in the difficult times in which we live. Money may be tight these days, but you still need answers!

We work from our own UK-based DNA testing laboratories.  We do not send samples to other companies or abroad.

Our customer service department is highly experienced at answering DNA testing enquiries and is UK based, ONLY. We operate a nationwide service from The Durham Genome Centre, Co. Durham, details can be found at www.durhamgenome.com and on www.compgeno.com.

Of course, we cannot offer a value brand for more complex testing or for legal (accredited) purposes, but if this is required, then the Complement Genomics Ltd laboratory will be there to help you. Please note that a different scale of charges will apply but please contact us if legal testing is required.

Do you need a legal DNA test?

If you are a member of the general public and wish to have a legal DNA test, please go to dadcheckgold.com, where we offer our accredited (legal) DNA testing, which can include persons from overseas.

DNA tests ordered through "That DNA Company" cannot be used for legal purposes. Please see dadcheckgold.com for this type of test.
