The Analytical Toxicology Laboratory was established in 1974 and provides an analytical toxicology service for Cardiff and Vale University Health Board and other hospitals within Wales and across the UK. The laboratory is based at University Hospital Llandough.
The laboratory offers toxicology analysis (such as toxic alcohols) and screening for drugs of abuse as well as a range of therapeutic drug monitoring. The laboratory employs a range of analytical techniques including immunoassay, chromatography and mass spectrometry.
These laboratory services cannot be accessed directly by patients - a referral from a GP or specialist doctor is required (depending upon the condition involved). If you have any questions about the services available and how these can be accessed by you or your family, please contact your GP to discuss. They should also have information about the funding of these tests within your area as this varies both within and outside of the UK.
