Urine drug testing is the most prevalent method for screenings, widely recognized nationwide, and the sole type approved for DOT-regulated drug tests in accordance with 49 CFR Part 40. This approach evaluates a urine sample to identify recent drug use, alcohol markers, or metabolites. The process is confidential, streamlined, and designed to produce legally defensible outcomes for employers, individuals, and judicial mandates.
Testing Methods & Collection Process
1. Donor Identity Verification
The donor furnishes legitimate government-issued identification and completes necessary chain-of-custody documentation before testing commencement.
2. Secure Collection Environment
Specimens are gathered in a controlled restroom setting, protecting the integrity of the test. Items may be restricted, water secured, and toilets dyed as part of security protocols.
3. Chain of Custody Documentation
A federally sanctioned Chain of Custody Form (CCF) ensures sample integrity from collection through laboratory analysis.
4. Temperature & Validity Checks
Post-collection, the specimen's temperature and appearance are validated. The laboratory conducts additional tests for validity, checking creatinine levels, pH, and specific gravity.
5. DOT Split Specimen
DOT urine samples are divided into two Bottle A for primary analysis and Bottle B for a retest if contested. For non-DOT tests, only one vial is collected.
6. Laboratory Screening & Confirmation
At SAMHSA-certified labs, samples undergo two-step analysis:
7. MRO Verification
A Medical Review Officer examines non-negative results, assessing potential medical explanations with the donor before finalizing.
Additional time may be necessary in cases like shy bladder or for further confirmation needs.

Testing Methods & Collection Process

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.

An alcohol urine test locates recent alcohol use by recognizing ethanol metabolites in urine, commonly utilized in workplace settings, legal obligations, and post-incident scenarios. Although it does not gauge present impairment, it offers a brief detection span lasting a few hours, providing a rapid, economical screening method.
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.
