Ethyl glucuronide (or "EtG") is a metabolite produced when alcohol is in the bloodstream. It is identified as a marker in alcohol hair testing, through a patented analytical process that provides forensic evidence of the pattern of alcohol abuse - or absence of it. The more alcohol a person consumes the greater amount of EtG markers are present in the hair.

EtG lasts for up to five days in urine, and confirms that someone has had a drink in that time. The presence and detection of EtG in hair now provides a longer window of detection of up to three months.

The UK courts recognise the presence of alcohol traces in human hair as reputable evidence in court. Trimega Laboratories have provided thousands of tests to the UK courts using its ISO9001 quality processes in accordance with UKAS standards.

Features of EtG alcohol testing

• Identify the amounts of alcohol an individual has consumed over a particular period.
• Identify long-term alcohol users, offer help and improve treatment success rate - treatment can then be monitored periodically as their hair grows.
• Prove a parent is fit to have custody of their children because they show no signs of abuse.
• Identify an alcohol abuser in a safety critical job before you hire them.
• Prove someone does not have an alcohol problem and is fit to lead for a position in public office, for example.
