chXout® Applied Genetics is a registered trademark of Complement Genomics Ltd, based at the prestigious Durham Genome Centre.

The Durham Genome Centre can be found in the lovely village of Lanchester, County Durham. It is home to chXout and further Complement Genomics services.  

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.

DNA species ID

chXout® is the UK’s trusted service for DNA bird sexing. We also offer parentage and species ID tests.

A bird DNA test? Not something you hear every day?! Thanks to our rural location we were fortuitously led to developing our first non-human testing service. We were asked to look into the possibility of DNA sexing peregrine falcons and from there hatched chXout®.

Our skilled staff and state of the art laboratories are at the forefront of using DNA technology in ornithology. We provide our bird DNA test services to animals collections, breeders, falconers and the general public all over the UK.

Each year from around April to the end of June we experience a very busy “bird season!” This is thanks to our well-known and extremely popular bird sexing service. Alongside bird sexing, we carry out species identification and parentage testing. All bird DNA test services are available year round for your convenience.

BIRD SPECIES

We are able to determine the sex of many species of birds. Our bird species list can be found here. Please remember that this list is continually being updated, so if you are unable to find your species, please do not hesitate to get in touch.

If we have not sexed a bird of your species before, we recommend, if possible, sending a sample from the same species which you know to be female. We can test this alongside your sample to aid our analysis.

Environmental Services

Bat Species Identification

Our environmental services are designed to aid surveys of protected species such as bats and great crested newts.

We are UK based, providing experienced and affordable environmental services at The Durham Genome Centre in Lanchester, County Durham. Our friendly, dedicated customer service staff are here for all of your questions and queries at every stage in the process.

Our bat species identification service is used to help identify any of the 17 species known to breed in the UK.

In 2022 we were pleased to launch our Great Crested Newt (GCN) eDNA testing service. We are proud to have achieved a perfect score in the annual FAPAS proficiency testing scheme in both 2022 and 2023. Unfortunately we are unable to offer the GCN eDNA service for the 2024 season, however, we are planning to be back for 2025.

If you have any research projects or ideas you think we may be able to help with, please do get in touch!
