An EtG (Ethyl Glucuronide) urine test is a sensitive method discerning alcohol use up to 80 hours post-consumption. As EtG is a direct derivative of ethanol, this test is widely exercised by courts, rehab programs, and compliance monitoring organizations.

Utilizing DOT-sanctioned breath Alcohol Devices (EBTs), these tests provide instant, admissible results. Essential for DOT-covered employees, they're also prevalent in workplace, accident aftermath, and reasonable suspicion testing scenarios.
The blood alcohol test directly quantifies ethanol in the bloodstream, esteemed for its accuracy in determining impairment. This method is utilized by hospitals, law officials, and legal entities, particularly valuable for DUI cases, emergency care, and intensive legal investigations.
A PEth (Phosphatidylethanol) blood test discerns chronic or substantive alcohol consumption by identifying unique alcohol biomarkers in red blood cells, sensitive up to 2-3 weeks. Regarded as among the most reliable indicators of extended drinking behaviors, it sees common use in family law, control programs, treatment centers, and sensitive industry pre-employment screenings.
Offering a 90-day detection range, the EtG hair alcohol test examines ethanol metabolites in the hair shaft, understanding repeated or chronic use rather than one-time events.
