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.
Limitations of Urine Drug & Alcohol Testing

Hair testing emerges as a pivotal approach for long-term substance use detection, providing a comprehensive 90-day window of insight into an individual's drug or alcohol habits by analyzing metabolites lodged within the hair matrix. Ideal for workplaces, legal scenarios, and more, this method offers reliability that surpasses the limitations of shorter-term detection tests like urine sampling.
While slightly longer due to in-depth processing, hair testing offers accurate and substantial substance use insight unmatched by other methods.

An alcohol urine test detects recent consumption through ethanol metabolite identification, primarily used across workplaces, court requests, and post-incident environments. Although real-time impairment isn't measured, a brief detection window allows cost-effective screenings.
The sensitive EtG (Ethyl Glucuronide) urine test captures 80 hours post-consumption alcohol usage, favored by judicial, rehabilitation, and compliance settings for extended detection windows and result reliability.
A breath alcohol test determines current impairment by sampling deep lung air alcohol concentration, with tests conducted using DOT-certified equipment delivering instantaneous, legally-defensible outcomes. This test holds significant value in workplace, accident, and suspicion bases.
The blood alcohol test analyzes ethanol levels within the bloodstream, recognized for high accuracy especially in cases like DUI investigations and emergency medical services.
A PEth (Phosphatidylethanol) blood test detects chronic or heavy drinking by identifying specific biomarkers within red blood cells, offering up to a 2-3 week detection window highly regarded for its long-term behavioral insights, especially in family, monitoring, and safety-preparedness contexts.
