Alcohol hair strand testing explained

Our hair strand testing for alcohol detects two types of markers; ethyl palmitate (EtPa) and ethyl glucuronide (EtG) as standard. These markers are ‘by-products’ created by the body in the presence of alcohol so allow us to assess alcohol consumption. 

Hair can provide alcohol detection for months and grows at an average rate of one cm per month. For example, if a three month retrospective analysis is required, a three cm section of scalp hair will be used. We can provide analysis for up to six months. 

We can also analyse smaller sections for the presence of EtPa and EtG but the results should be interpreted with caution. 

We strongly recommend that EtPa and EtG analysis is used in conjunction with other forms of evidence such as blood alcohol tests (liver function and carbohydrate deficient transferrin), clinical assessments and history of alcohol abuse to obtain a comprehensive picture
