What the Heck is EtG?
Ethyl Glucuronide, aka EtG, is a metabolite of ethanol. A metabolite is simply what your body produces in response to the ingestion of ethanol.
Two Types Of EtG Testing
- Hair follicle EtG alcohol test – Hair is cut at skin level (not actually the follicle) and sent to the lab where it is washed and otherwise prepared before testing.
- Urine EtG alcohol test – Urine is collected as with any other drug test and sent to the lab for testing.
The procedures for the tests are similar and would either produce a negative or a positive EtG test, depending on the concentration of EtG in the body.
There is a difference in the two tests in terms of the “look-back” period. A “look-back” period is also known as the detection window, or how much far in the past the lab can detect alcohol use.
The two tests are explained below:
- EtG Hair Follicle Alcohol Test – The look-back period in this test is approximately 90 days. If a person consumed alcohol in the last three months, this test would report a positive EtG test result.
- Urine EtG Alcohol Test – The look-back period is approximately 80 hours, though it can vary. If a person consumed alcohol in the last three days or so, this test would report a positive EtG test result.
Who Order an EtG Test?
Since alcohol is legal, EtG alcohol tests are generally not used in the workplace. They are used primarily for zero tolerance situations. Examples:
- A court-ordered requirement due to a child custody case;
- For proving innocence in a Driving Under the Influence (DUI) arrest;
- As follow up to a DUI case in some states
- Some domestic disputes
- Family members who want to keep an eye on a loved one.
How to Pass an EtG Alcohol Test
The obvious answer is – the only safest way to pass an EtG alcohol test is to abstain consuming alcohol. That is why you’ve been required to take the EtG alcohol test: zero tolerance.
