Our offer includes hair analysis for private purposes, for example for self-monitoring, to prepare for an appointment as part of a driving aptitude test or as a safety measure for employers. It is a laboratory analysis method to detect the consumption of alcohol and/or drugs in the hair. The method (based on tandem mass spectrometry, including preliminary and search tests) is a suitable means of proving abstinence from a specific substance. In addition, hair analysis can also be used to draw conclusions about the consumption behavior of a specific substance. Only head hair is used for this.
