The EtG (Ethyl Glucuronide) urine test is highly sensitive, identifying alcohol use up to 80 hours post-intake. As a direct ethanol metabolite, it's extensively applied by courts, rehab, and monitoring agencies, giving a longer window than standard urine tests with reliable results.
A breath alcohol test ascertains current impairment by evaluating alcohol concentration in deep lung air. Conducted with DOT-approved devices, it delivers instant, lawful results crucial for DOT employees, workplace environments, incidents, or suspicious circumstances.
A blood alcohol test provides an accurate measure of circulating ethanol, preferred by hospitals and law enforcement for precision, especially in DUI, critical care, and legal matters.
PEth (Phosphatidylethanol) blood tests identify heavy alcohol consumption by tracing alcohol biomarkers within red blood cells. Effective up to 3 weeks post-use, it's a solid indicator for habitual drinking, often used in legal, rehabilitation, and pre-employment screenings.
The EtG hair test offers a 90-day window by analyzing alcohol metabolites in hair shafts, ideal for detecting ongoing patterns rather than single events. Legal, custody, and monitoring programs leverage its accuracy and tamper-resistant nature.
