When you purchase the Saliva Alcohol ETG Laboratory Confirmation Test Kit, you receive an oral fluid specimen sample collection device, a pre-paid UPS ground shipping label and a chain of custody form.
Ethanol glucuronide (ETG) is a direct biomarker resulting from the consumption of alcohol. It can be detected using urine or saliva samples. This saliva alcohol ETG test detects the presence of ethyl glucuronide ingested within the previous 3 to 4 days (80 hours) through saliva samples, and offers an extended window for assessment of drinking status of up to 5 days. The test serves as a reliable tool to identify individuals who are legally prohibited from consuming alcohol, either by law or by their employer.
This positive confirmation test includes a chain of custody form which you can use to send the sample back to us for lab analysis of the positive result. Simply fill out the form, include the positive result, and use the UPS ground label that comes with the kit to send the test to the lab. The final results will be available in 3-7 business days from the date the lab receives the test.
Cut Off Level for this ETG test is 50ng/mL
Window of Detection:
ETG test is likely to detect that alcohol was ingested within the past 3 or 4 days. The detection time of alcohol in urine drug tests can be as long as 80 hours. This saliva alcohol ETG test offers an extended window for assessment of drinking status of up to 5 days.
According to the Substance Abuse and Mental Health Services Administration (SAMHSA), the cutoff value selected to distinguish specimens as positive or negative should consider the base rate of problem drinking in the population being evaluated, the individual's likely exposure to products containing non-beverage alcohol, and the consequences for the individual and society of the individual's being erroneously labeled. Establishing a reliable cutoff with high positive predictive value requires research in the population and discussion of the various contexts in which the test might be applied.

A positive ETG is not proof of intentional alcoholic beverage consumption. Low level positive tests may occur due to incidental exposure. All positive screens are considered presumptive and we recommend confirmation. This saliva alcohol ETG test uses a cutoff level of 50ng/mL to try to avoid these incidental exposure levels.
Limitations of the test:
This test doesn't find out why and how the ETG has been produced or the identity of the real substance which has been metabolized to produce ETG. The test only detects the presence of ETG. Additionally, there are no known threshold levels determined for ETG that can distinguish between the incidental exposure and the intentional consumption of alcohol. False positives are possible.
Ethylglucuronide (EtG) was described as early as the 1950's. However, clinical use of the test as an alcohol marker began in 2001 when Dr. Friedrich Wurst, in Switzerland, and Dr. Gregory Skipper, in the USA, reported a study of alcoholics in a psychiatric facility in Germany. Their findings demonstrated that EtG was a more sensitive and reliable indicator of both drinking and abstinence than was a conventional urine alcohol test. Dr. Skipper recognized that urine EtG would be a valuable test in monitoring professionals. The Federation of State Physician Health Programs estimates that over 9,000 physicians are in monitoring in the USA. An essential issue in justifying the continued safe practice of recovering physicians involves the ability to reliably document their abstinence.
Advantages of the test:
- This saliva alcohol ETG test is ideal for zero tolerance and abstinence situations.
- Detects recent usage more accurately and for a longer period of time than standard testing.
- Strong indicator of alcohol ingestion within the previous 3 to 4 days.
- Helps identify relapse to drinking.
- ETG may be run on saliva specimens in conjunction with other drug testing panels.
- Helps in evaluating interventions for alcohol problems.
