Alcohol Urine Drug Test

This test method identifies recent alcohol intake through the detection of ethanol metabolites in urine. Predominantly employed for workplace checks, legal requisitions, and post-incident assessments, it doesn't pinpoint current impairment but functions over a short detection period, offering an expedient and budget-friendly screening option.

ETG Alcohol Test (Urine)

The Ethyl Glucuronide (EtG) urine test stands as a sensitive measure detecting alcohol consumption up to 80 hours past intake. As a direct by-product of ethanol, this test finds widespread application across courtrooms, rehab setups, and compliance monitoring nationwide, renowned for its accuracy and extensive detection window beyond traditional methods.

Breath Alcohol Test

Utilizing DOT-sanctioned breath analyzers, the breath alcohol test assesses current impairment via alcohol concentration in deep lung breaths, delivering instant and legally valid results. This modality is essential for DOT-regulated employees, and commonly enacted in workplaces following accidents or under reasoned suspicion.

Blood Alcohol Test

Offering exact ethanol concentration measurements in the bloodstream, this method ranks among the most accurate for assessing impairment. Employed in Claremont, CA's hospitals, law enforcement, and legal institutions, blood alcohol testing is vital in DUI cases, emergency medical responses, and rigorous legal probes.

PEth Alcohol Blood Test

PEth (Phosphatidylethanol) blood testing serves as an identifier of chronic or intensive alcohol consumption through alcohol biomarkers in red blood cells, extending detection for 2-3 weeks. This test holds high relevance in family law, monitoring regimens, treatment environments, and employment screenings in safety-conscious fields.

ETG Alcohol Test (Hair)

With a 90-day detection horizon, the EtG hair alcohol test explores alcohol metabolites embedded in hair, targeting patterns of chronic use rather than isolated consumption episodes. Courts, child custody deliberations, and prolonged monitoring programs employ this method for its durable and precise tracking ability against temporary abstinence efforts.

Through professional support, nationally accredited lab integration, and fast-paced scheduling, Accredited Drug Testing ensures each alcohol screening method accomplishes clear, defensible, and regulation-compliant results, empowering individuals and employers to remain informed and at ease with Claremont, CA's regulatory requirements.
