Ethyl glucuronide identified in commercial hair tonics
Forensic Science International, 2013Ethyl glucuronide (EtG) in hair is considered as a specific marker of ethanol consumption. Prompted by a report of positive EtG hair testings due to hair treatment with an EtG containing hair lotion, commercially available herbal hair tonics from supermarkets, drug-stores, and health food stores were analyzed for the presence of EtG and ethyl sulfate ...

Disappearance of ethyl glucuronide during heavy putrefaction
Forensic Science International, 2008There are previous publications showing the use of ethyl glucuronide (EtG), a non-oxidative metabolite of ethanol, as a marker of ante-mortem ingestion of alcohol in forensic autopsy cases. The problem of possible degradation or formation of EtG during putrefaction is however not well studied and the aim of this study was to investigate the possibility

Beta-Glucuronidase Activity: Another Source of Ethyl Glucuronide
Journal of Analytical Toxicology, 2022AbstractNumerous classes of endogenous and xenobiotic compounds are conjugated to uridine-5′-diphospho (UDP)-alpha-D-glucuronic acid which is catalyzed by human UDP-Glucuronosyltransferases (UGTs). The resulting beta-D-glucuronides can be hydrolyzed to β-D-glucuronic acid and the corresponding aglycone in a configuration retaining manner by beta ...

Determination of ethyl glucuronide and fatty acid ethyl esters in hair samples
Biomedical Chromatography, 2016AbstractHair testing for alcohol biomarkers is an important tool for monitoring alcohol consumption. We propose two methods for assessing alcohol exposure through combined analysis of ethyl glucuronide (EtG) and fatty acid ethyl esters (FAEEs) species (ethyl myristate, palmitate, stearate and oleate) in hair (30 mg).

Postmortem ethanol formation is a well-known problem in forensic toxicology. The aim of this study was to interpret findings of ethanol in blood, in a large collection of forensic autopsy cases, by use of the nonoxidative ethanol metabolites, ethyl glucuronide (EtG), and ethyl sulfate (EtS).

Cross-reaction of propyl and butyl alcohol glucuronides with an ethyl glucuronide enzyme immunoassay
Forensic Science International, 2014Ethyl glucuronide (EtG) in urine is considered a marker of recent alcohol consumption. Using immunoassays for EtG screening without confirmatory analysis bears a risk of getting false-positives as shown for trichloroethyl glucuronide from chloral hydrate medication and 1-propyl glucuronide from propanol-based hand disinfection. The aim of the study was

O16: Ethyl glucuronide in plant extracts
Toxicologie Analytique et Clinique, 2014Introduction The specificity of ethyl glucuronide (EtG) in hair as marker of alcohol consumption exceeds by far those of fatty acid ethyl esters. False positive cases are therefore very rare but not excluded as recent publications have shown.

Effect of Bleaching on Ethyl Glucuronide in Hair: An in Vitro Experiment
Forensic Science International, 2010Ethyl glucuronide in hair (HEtG) has recently gained great attention, because of its high sensitivity and specificity in the diagnosis of chronic alcohol abuse. Due to its high polarity hydrophilicity, a strong hair treatment followed by a shampooing may lead to removal/degradation of this molecule from hair matrix.To set up an in vitro study in order ...

Ethyl glucuronide and ethyl sulfate in the zebrafish after ethanol exposure
AlcoholEthanol exposure during pregnancy is an important problem and is the cause of fetal alcohol syndrome (FAS) and fetal alcohol spectrum disorder (FASD). The etiology of FAS and FASD can be elucidated using animal models. Recently, a novel model, the zebrafish (Danio rerio), has garnered the interest of researchers.

Ethyl glucuronide and ethyl sulfate in autopsy samples 27 years after death
International Journal of Legal Medicine, 2008The unique case of a 50-year-old known alcoholic whose corpse was exhumed 27 years after death is reported. The man apparently committed suicide by hanging, but many years later the case was questioned and homicide-linked to a long-lasting serial killer case-was suspected.
