Urine drug testing remains the predominant method used for screenings across the United States, approved specifically for DOT-regulated drug testing under the regulations in 49 CFR Part 40. This technique uncovers recent substance intake by examining urine for drugs, their metabolites, or alcohol indicators. The methodology is crafted to ensure accuracy, confidentiality, and legality, catering to the needs of businesses, private individuals, and legal mandates.
Delays might occur due to shy bladder, invalid samples, or follow-up lab confirmations or donor contacts.
Despite these shortcomings, urine testing remains a crucial and widely adopted legal and corporate alcohol and drug screening ritual across the globe.
Hair drug and alcohol testing, a rigorously reliable laboratory approach, examines long-term substance use patterns by analyzing drug metabolites retained in the hair shaft for up to 90 days. Unlike urine testing, which tracks recent consumption, this test is an optimal choice for workplace compliance, judicial scrutiny, child custody evaluations, and when a longer-term usage reflection is necessary.

An alcohol urine test is designed to detect recent alcohol consumption by identifying ethanol metabolites present in the urine. This testing method is extensively used in workplace settings, for court-ordered screenings, and post-incident analyses. Despite not measuring immediate impairment, it offers a narrow detection window of a few hours, making it a fast, cost-effective option for screening purposes.
The EtG (Ethyl Glucuronide) urine test is recognized for its sensitivity, being capable of identifying alcohol consumption up to 80 hours after intake. As EtG is a direct metabolite of ethanol, the test is favored by courts, rehabilitation programs, and regulatory agencies for its reliability and extended detection timeframe.
The breath alcohol test gauges present impairment by measuring the alcohol concentration in deep lung air. Performed using DOT-approved breath devices (EBTs), it offers immediate, legally defensible results, fitting for DOT-covered employees, workplaces, post-incident, and suspicion-based testing.
A blood alcohol test directly quantifies the amount of ethanol in the bloodstream, making it one of the most precise methods to assess impairment. It is routinely employed by hospitals, law enforcement, and legal professionals in DUI cases, emergency healthcare, and significant legal inquiries.
The PEth (Phosphatidylethanol) blood test identifies chronic or heavy alcohol usage by recognizing alcohol-specific biomarkers within red blood cells. The test can track use up to 2-3 weeks and is considered an exceptionally reliable marker for long-term alcohol consumption behavior, making it ideal for family law, monitoring, treatment centers, and safety-sensitive pre-employment screenings.
With a hair EtG test, a 90-day detection window is provided by analyzing alcohol metabolites entrenched in the hair shaft, spotting recurring consumption habits rather than single events. Its stability, accuracy, and resistance to abstinence efforts make it a staple in courtroom proceedings, child custody disputes, and extended monitoring initiatives.
