New Jersey EtG Testing

When an individual has been arrested on suspicion of driving while intoxicated, he or she will be asked to submit to one of three chemical tests: blood, breath or urine. While it is the least common of the three chemical tests, urine testing, also known as EtG testing, is one way that officers may test your blood alcohol content.

The EtG Testing Process

When you drink, a metabolite called Ethyl Glucuronide, or EtG, is produced in your body. During an EtG test, an officer will request a urine sample that will then be analyzed for the presence of EtG. The amount of EtG will help law enforcement determine your blood alcohol content.

Problems with EtG Tests

While it is an effective test to determine if someone has been drinking, it is not the most accurate. EtG can show up in a person’s urine sample for up to five days after that person has had a drink. What’s more, EtG may be present in the urine sample of someone who has eaten vanilla, used hand sanitizer or even used certain bathroom cleansers.

There are ways to defend against the results of EtG tests, especially in cases where low levels of this metabolite are found in a sample.
