If you are placed on probation for a DUI arrest in Washington state, one of the conditions is often not to consume alcohol. Probation and your alcohol treatment provider are given great latitude in enforcing that order, and most do so by requiring urinalysis (UA) tests.
Most people believe that they can pass a urinalysis if they have not been consuming alcohol recently. That used to be true but many treatment providers and probation officers are now utilizing Ethylglucuronide (“EtG”) Urine tests. EtG urine testing detects alcohol metabolites in your urine. Depending on the type of screening that is performed some studies suggest that an EtG test can detect alcohol metabolites in your urine as far back as 80 hours from the time the alcohol entered your system.
