A breathalyzer only catches alcohol in the moment. An EtG/EtS urine test detects the metabolites ethyl glucuronide and ethyl sulfate for up to ~80 hours after drinking — the standard for abstinence-monitoring and court-ordered programs.
EtG vs. breath/blood alcohol
Breath and blood measure current impairment; EtG/EtS confirm recent use even after alcohol has cleared. That makes EtG the right tool for zero-tolerance monitoring, probation, and treatment programs.

Common questions
How long does EtG detect alcohol?
EtG/EtS can detect alcohol use for roughly 80 hours after consumption.
Can EtG detect one drink?
EtG is sensitive; program cutoffs are set to balance sensitivity against incidental exposure. LabX reports the confirmed level.
