Will alcohol free beer show up on EtG?

Could you please elaborate on whether alcohol-free beer would potentially trigger a positive result on an ethyl glucuronide (EtG) test? I'm curious as to whether the minute traces of alcohol or other compounds present in non-alcoholic beverages could be detected by this type of screening, especially for individuals who may be required to abstain from all forms of alcohol consumption for personal, professional, or legal reasons. It would be insightful to understand the specifics of how EtG tests work and their sensitivity levels when it comes to detecting even the slightest amounts of alcohol or related compounds.
