Through the measurement of ethyl glucuronide in hair (hETG), it is possible to assess chronic alcohol abuse over time. In this paper, we present a study on hETG in Italian prison inmates. Analyses were performed by LC-MS according to a previously published method. Results were evaluated using the cut-offs established by the Society of Hair Testing. Positives samples (ETG > 30 pg/mg) accounted for 6% of all subjects, with concentrations ranging from 42 pg/mg up to 270 pg/mg, abstinent subjects (ETG < 7 pg/mg) accounted for 88%, and moderate alcohol consumption (7 < ETG < 30 pg/mg) for 6% of the subjects. No females displayed ETG values above 30 pg/mg. Among positive samples, only two subjects did not declare heavy alcohol consumption and were found strongly positive at 210 and 270 pg/mg. To the best of our knowledge, this represents the first study on ETG hair concentration on prison inmates.
通过测量头发中的乙基葡萄糖醛酸（hETG），可以长期评估慢性酒精滥用情况。在本文中，我们展示了一项针对意大利监狱囚犯hETG的研究。分析采用液相色谱 - 质谱联用仪（LC-MS），依照先前发表的方法进行。结果依据毛发检测协会设定的临界值进行评估。阳性样本（ETG > 30 pg/mg）占所有受试者的6%，浓度范围为42 pg/mg至270 pg/mg，戒酒者样本（ETG < 7 pg/mg）占88%，适度饮酒者样本（7 < ETG < 30 pg/mg）占受试者的6%。没有女性的ETG值高于30 pg/mg。在阳性样本中，只有两名受试者未宣称大量饮酒，但检测发现其ETG值分别高达210 pg/mg和270 pg/mg，呈强阳性。据我们所知，这是第一项关于监狱囚犯头发中ETG浓度的研究。
