UCT Clean Screen® EtG SPE Sorbent cited in Alcohol/Drugs Licensing Article

Monday, March 26th, 2018

Elena Lendoiro et al., published in Forensic Science International (/ on the use of UCT’s Clean Screen® EtG solid phase extraction sorbent to determine the ethyl glucuronide (EtG) content of drivers suspected of alcohol/drugs driving cases under voluntary conditions. A validated analytical method for EtG was established which had a limit of quantification (LOQ) of 5 pg/mg of hair. It was found that 22 hair samples were positive for EtG where concentrations (20.7-1254.1pg/mg) were higher than the Society of Hair Testing (SoHT) cut-off for chronic alcohol consumption (≥30 pg EtG per mg of hair) in 21 cases.
