Clean Screen EtG paper

Forensic Toxicologists working in the area of drugs and driving cases are being challenged to meet stricter regulations. In a new paper authored by Ronald Agius et al (Forensic Science International, October 2011), the Clean Screen EtG column (CSETG203) has been successfully employed to meet these guidelines, specifically applied in Germany to drivers wishing to regain their licences. In this paper, Ethyl Glucuronide (EtG), the biomarker for ethyl alcohol consumption, was determined in urine samples down to 0.1 mg per L using only 600 microliters of sample. The method was applied to 78 real samples of urine in order to meet German authority regulations. In addition hair samples were also analyzed. 50 mg of sample was employed to test the method against the Society of Hair Testing (SoHT) criteria. The levels of detection of this method using the Clean Screen EtG column (2.8 pg/ mg) were met.
