What is an ETG Test?
An ETG test for alcohol is a rapid on-site urine test which detects the presence of Ethyl Glucuronide (ETG) which is a direct metabolite of alcohol (ethanol). The presence of ETG in urine may be used to detect recent alcohol ingestion, as it is detectable in urine even after ethanol is no longer measurable.
Rapid ETG tests give results in less than 10 minutes and have a high accuracy level. Currently the format is a single dip ETG urine test strip. Over the coming years you will see an ETG test integrated into combination drug test cups, allowing the test to be performed as part of routine multi-drug screening
ETG test detections times
The ETG test is also known as the 80 hour alcohol test but actually the detection time is usually shorter than 80 hours. Urine ETG testing is ideal for zero tolerance alcohol treatment programs and alcohol abstinence enforcement where urine testing twice weekly ensures no ethanol ingestion compliance.
ETG test facts and myths
ETG tests remain positive long after blood alcohol levels return to zero ?
True. The exact period depends how much alcohol was consumed, but this can be as long as 80 hours after ethanol was consumed.
ETG tests will determine when and how much alcohol was consumed ?
False. A rapid ETG test only shows ethanol was consumed at some point prior to the test, not when or how much.
ETG tests can give false positive results from ethanol produced in the body in diseases such as diabetes?
False. The cut off level set for the rapid ETG test is well above the levels expected in metabolic diseases such as diabetic keto-acidosis and liver disease.
