ETHYLGLUCURONIDE ALCOHOL SCREENING

What is Ethylglucuronide?

• Ethylglucuronide (EtG) is a breakdown product ("metabolite") of beverage alcohol consumption.
• When Alcohol is ingested, EtG is quickly created.
• EtG can be detected in urine up to 80 hours after consumption.

Why use Ethylglucuronide testing?

• All common alcohol tests other than EtG test for actual alcohol in the body.
• Alcohol is eliminated from the body at the average rate of one drink per hour, although this varies by weight and gender.
• Alcohol in the body reflects current use - the person has been drinking in the past few hours, dependent on quantity consumed.
• Only EtG goes back in time. So EtG testing can confirm sobriety or reveal secret drinking.

How is Ethylglucuronide detected?

• EtG is detected through urine testing.
• EtG testing can only be performed in a laboratory-can not be determined through a "rapid" or "dip" test.
• Laboratories use sophisticated instruments to detect EtG:
• Liquid Chromatography, Tandem Mass Spectrometry (LC/MS/MS) is the most sensitive test.
• Gas Chromatography/Mass Spectrometry (GC/MS) is less sensitive
• Immunoassay testing is the least sensitive method.

EtG Testing is a Highly Accurate Method for Monitoring Recovery

• Since an EtG negative is proof of abstinence for alcohol use, it is an effective method to verify on-going recovery.

Concerns Regarding Inadvertent Alcohol Exposure

• Positive EtG are always confirmed by reference labs; initial positive are subject to confirmatory re-testing, so a positive EtG will always reflect alcohol in the individual's body.
• All EtG's collected by ESM are tested at 2000ng, which is the highest level of detection to avoid any cause of a false positive.

EtG is the Best Available Method for Monitoring Alcohol Use

• EtG is Accurate- the absence of false positives makes it an extremely reliable method to monitor recovery.
• When EtG positives are disputed, alcohol use can be evaluated with alternative assessments and tests.
• Other technologies, such as Transdermal testing, have limited data regarding false positives or the impact of inadvertent exposure in vulnerable individuals: EtG testing can be used to confirm the results of technologies such as Transdermal testing.
