What You Need To Know About EtG Testing


EtG testing in Metro Detroit

What is EtG Testing?


An EtG test is a type of alcohol testing that determines if you’ve had alcohol in your system recently. EtG stands for ethyl glucuronide, a metabolite that’s produced by your liver when it breaks down ethanol also known as ethyl alcohol.

EtG testing is used to keep track of alcohol abstinence in a variety of situations, such as court cases, employee drug testing, DUI probation, child custody and many other.


Detection Time Frame


An EtG test is most accurate within two days of drinking, however it can detect alcohol for up to five days if you were drinking heavily. EtG test stays in the urine much longer than in blood or oral fluid, so that makes EtG test the most accurate choice with several days of detection time.


What Does a Positive EtG Test Mean?


A "high" positive EtG test (for example, >900ng/mL) may indicate: heavy drinking on the same day or the previous day and or light drinking on the same day as the test.


Triggers for False Positive on EtG Test


The key to getting the most accurate result from your EtG test is avoiding anything containing alcohol that includes household products such as cold medicines, mouthwash, antiperspirant, hand sanitizer and cleaning products.


Things You Can Do if You Tested Positive on EtG Test


If you have a positive EtG test due to incidental exposure to alcohol, you may be able to retake the test. Always consult with your probation officer if you were court ordered to take an EtG test.


Avoid anything containing alcohol for several days should result in a negative EtG alcohol test result, however if you can’t stop drinking alcoholic beverages long enough to have a negative EtG test, it’s time to seek professionals to help you with alcohol abuse.
