Nationally, urine drug testing is the predominant choice for screening, especially for DOT-regulated drug testing under the stipulations of 49 CFR Part 40. This method examines a urine sample to detect drugs, metabolites, or alcohol markers to reflect recent substance usage. It's structured to be both secure and confidential, furnishing results that are not only accurate but legally defensible, serving the needs of employers, individuals, and judicial requirements.
Testing Methods & Collection Process
Additional time might be needed in scenarios involving shy bladder, invalid specimens, or further laboratory or donor interaction.
Limitations of Urine Drug & Alcohol Testing
Despite these drawbacks, urine screening remains a broadly accepted and practical solution for drug and alcohol testing throughout various settings.
In Berkeley, CA, Hair Drug and Alcohol Testing offers a dependable approach for assessing long-term substance usage, extending beyond the brief detection timeframe of urine testing. By examining the hair shaft for drug metabolites over a 90-day detection period, this method delivers valuable insights into an individual's substance use history, making it highly suitable for workplaces, legal cases, child custody disputes, among other scenarios requiring an extensive view of use patterns.
Testing Methods & Collection Process
1. Donor Identity Verification
The process initiates with the donor providing a valid ID, accompanied by the completion of necessary consent and chain-of-custody forms to ensure accurate procedural documentation.
2. Hair Collection Procedure
A trained technician extracts a small sample of hair, typically 100-120 strands, from the crown of the head for optimal results. In cases where head hair is unavailable, body hair can serve as an alternative. The procedure is seamless, non-invasive and observed directly.
3. Chain of Custody Documentation
Completion of the Hair Drug Test Custody and Control Form documents the collection, sealing, and transfer of the sample to safeguard its legal defensibility throughout the testing process.
4. Laboratory Preparation & Analysis
At the laboratory, the sample undergoes several forensic procedures:
Subsequent laboratory tests include:
5. Metabolite Detection
Drug metabolites integrate into the hair shaft during growth, documenting long-term substance use that is exceptionally hard to tamper with.
6. MRO Review
A certified Medical Review Officer (MRO) meticulously examines all non-negative results and evaluates potential medical explanations before issuing the final outcome.
How Long Do Hair Test Results Take?
The processing time for hair testing is generally longer compared to urine testing, but the depth of insight achieved through this method is unparalleled.
Limitations of Hair Drug & Alcohol Testing
Despite some limitations, hair testing remains a premier choice for uncovering prolonged substance usage, favored by employers and legal experts aiming for unimpeachable and tamper-proof results.

The alcohol urine test is an effective method for detecting recent alcohol intake through ethanol metabolites in urine and is frequently utilized for workplace assessments, judicial mandates, and post-incident inquiries. While it does not gauge present impairment, its short detection timeframe, spanning several hours, offers an expedient, economically accessible screening solution.
Employing the EtG (Ethyl Glucuronide) urine test offers a highly nuanced method to confirm alcohol consumption up to 80 hours after use. As EtG is a proximal ethanol metabolite, its application finds firmness in judicial circles, rehab institutions, and compliance checks due to its expansive detection period beyond typical urine evaluations and its pronounced accuracy and reliability.
The breath alcohol test specifically measures immediate impairment by quantifying alcohol levels in deep lung exhalation using DOT-approved breath alcohol devices (EBTs), generating instantaneous, legally verifiable outcomes ideal for DOT-affiliated employee assessments, corporate environments, post-incident analysis, and substantiated suspicion audits.
Directly quantifying ethanol in the bloodstream, the blood alcohol test is revered for its unrivaled accuracy in impairment detection and is often employed by medical professionals, law enforcement, and legal entities, particularly in DUI cases, emergency medical scenarios, and critical legal investigations.
The PEth (Phosphatidylethanol) blood test identifies chronic or habitual drinking by revealing alcohol-linked biomarkers within red blood cells. With detection spanning up to 2-3 weeks, it is acclaimed as a robust indicator of persistent drinking patterns and finds extensive use in family law adjudication, monitoring circuits, rehabilitation environments, and selective pre-employment screenings for sectors with rigorous safety obligations.
Analyzing EtG metabolites in hair strands provides a 90-day reflection on alcohol usage patterns, highlighting habitual or frequent consumption over isolated incidents. Courthouses, child custody hearings, and monitoring agendas favor this test for its consistency, accuracy, and immunity to fleeting sobriety efforts.

This is by far the easiest way to get my lab work ordered and paid for. The phone calls are short and to the point. They don’t try to push extra sales on you and when I walk in to the clinic I simply show my donor pass and with in a matter of minutes I’m done. I will continue to use ADT in the future.
