ChXout is a registered trademark belonging to Complement Genomics Ltd, a long established, reliable, highly recommended and trusted DNA testing company. The ChXout service has been designed to serve the non-human animal DNA testing market with species identification, gender determination and species quantitation services ( for example, in meat and fish products).

We have for 15 years worked on human DNA testing, both business to business viadadcheckGold and business to consumer (dadcheckSilver and That DNA Company).

This includes paternity and relationship questions using DNA testing technology and we have our own UK based ISO/IEC 17025 accredited laboratories which are accredited by the UK Ministry of Justice for section 20 paternity testing.

Our contract molecular biology division, Geneblitz, has successfully delivered many genotyping and biomarker projects for international CROs who are involved in clinical trials for pharmaceuticals intended for human use. We operate this service to GCP.

We are also research active in both human and non-human genetic and biomarker testing and have been involved in a major project with the National Institute for Health Research examining the biomarkers which can predict healing in the diabetic foot ulcer.

We are based in the prestigious Durham Genome Centre.
