About Us

ChXout® is a registered trademark of Complement Genomics Ltd. based at the prestigious Durham Genome Centre.

The Durham Genome Centre can be found in Lanchester, County Durham. It is home to chXout® and further Complement Genomics services which you can find out more about below.

Complement Genomics was formed in April 2000 with a vision to truly take DNA testing to the general public. We have since continued to bring forward new DNA testing services to both businesses and the general public. This includes services such as human identity testing, as well as genotyping and Covid-19 screening.

Our rural idyll fortuitously led us to the DNA sexing of peregrine falcons and as a result our flagship non-human DNA testing service chXout® was formed. We offer a range of services suitable for the general public, professionals and conservation projects alike.

A busy “bird season” every year provides gender and parentage testing to a wide range of clients. We are proud to offer our bird services year round. Additionally, our Professional Services include species identification DNA tests for bats and our Great Crested Newt eDNA service.

Here at chXout® we are passionate about all things conservation and biodiversity with ongoing development into our Citizen Science service. Keep an eye out for interesting news updates, research and thoughts through our blogs and social media!  Similarly, we are keen to get involved in any local projects or research ideas you may have so please do not hesitate to get in touch with the chXout® team.
