chXout® is a UK‑based applied genetics DNA testing service specialising in bird sexing, species identification, and broader ecology‑related genetic testing from micro-organism to fungi identification. The brand is owned by Complement Genomics Ltd, a long‑established genetics laboratory.
If it has DNA, we’ll have a go at identifying it. All testing carried out in our UK laboratory.
Male or female at any age, from a feather, blood or eggshell membrane. Results in 2–3 working days.
From £22Identify a bird species from a sample — including forensic analysis of bird strikes on aircraft.
£75DNA parentage testing to verify breeding programme records for falcons, hawks and eagles.
£72–£90Confirm pedigree records for racing and show pigeons with DNA parentage testing.
£55–£165Species-level ID using ITS DNA barcoding against the NCBI GenBank database.
£42Identify bat species from droppings or other samples — supporting protected species surveys.
£54–£66DNA sexing for beaver reintroduction and monitoring projects.

chXout® is a leading UK provider of wildlife DNA testing, offering fast and reliable services including DNA bird sexing, species identification, parentage testing, and ecological eDNA analysis. Based at the Durham Genome Centre in Lanchester, County Durham, we deliver high‑quality, UK‑based genetic testing trusted by breeders, pet owners, ecologists, and conservation professionals.
Complement Genomics Ltd is a leading and highly rated UK based molecular biology laboratory which has been conducting contract services for over 25 years.
The company is based in the prestigious Durham Genome Centre in Lanchester, County Durham.
A fortuitous request for DNA sexing of peregrine falcons led to our flagship non-human DNA testing service, chXout.
We now conduct a wide range of non human DNA testing, such as parentage (raptors, pigeons), sexing in a huge range of non-diamorphic avians, sexing beavers, species ID (fungi, animals, plants) and forensic analysis of bird strikes on aircraft, bat and newt identification.
Plus, we engage with citizen science (butterflies, moths, bees) and research (conservation) projects that are of interest to us. We love fungi and the biology of small things, for example lichens and insects. If it has DNA, we will have a go at species ID !
Alongside our species testing, we have a unique air sampling capability for environmental monitoring using next generation sequencing (eDNA), plus a sophisticated capability for microbial determination and pathogen detection in the AgBio and biosecurity sector.
Four simple steps from order to results.
