In El Sobrante, CA and across the country, urine drug testing is the most widely utilized screening method and is the exclusive test type sanctioned for DOT-regulated drug testing under 49 CFR Part 40. By evaluating a urine sample for drugs, drug by-products, or alcohol markers, recent substance use can be detected. This standardized and confidential procedure ensures the delivery of precise, legally rigorous results for employers, individuals, and legally ordered programs.
Testing Methods & Collection Process
1. Donor Identity Verification
The donor must present a legitimate government-issued ID and complete the necessary chain-of-custody signatures before initiation of testing.
2. Secure Collection Environment
Urine samples are collected in secured restroom facilities to deter tampering, often involving restrictions on personal belongings, securing water sources, and dyeing toilet water as part of security norms.
3. Chain of Custody Documentation
A federally endorsed Chain of Custody Form (CCF) meticulously tracks the sample's journey from collection through to laboratory analysis, preserving the test's integrity and legal viability.
4. Temperature & Validity Checks
Post-collection, the specimen is scrutinized for temperature and appearance accuracy. Additionally, validity testing including checks for creatinine levels, pH, specific gravity, and adulterant presence is conducted.
5. DOT Split Specimen
DOT urine tests involve bifurcation into two vials: Bottle A is utilized for primary analysis and Bottle B for retesting in case of a challenge. For non-DOT tests, a single vial is collected.
6. Laboratory Screening & Confirmation
Samples are processed in SAMHSA-certified laboratories through a dual-step process:
7. MRO Verification
Non-negative results are substantiated by a licensed Medical Review Officer (MRO), who validates the data and discusses any possible medical justifications with the donor prior to final result dissemination.
Additional processing time may be necessary for situations involving shy bladders, invalid samples, or where lab validation and donor interaction are essential.

Despite these limitations, urine tests remain the leading choice for drug and alcohol detection across the nation.

A breath alcohol test evaluates the present impairment level by assessing alcoholic content in deep lung air. Administered through DOT-sanctioned devices, breath tests render instant, legally defensible outputs, obligatory for DOT-regulated employees, and serve imperative in workplace assessments, post-crash scrutiny, and reasonable suspicion inquiries.
The blood alcohol test delivers precision, appraising ethanol levels circulating within the bloodstream, recognized especially within hospitals, law enforcement, and legal frameworks for its accuracy, notably in DUI cases, emergency interventions, and urgent legal investigations.
The PEth test identifies chronic or substantial alcohol use through phosphatidylethanol biomarkers inside red blood cells, tracing usage up to 2-3 weeks. It stands as a substantial indicator of long-term drinking patterns amidst family law disputes, oversight initiatives, therapy facilities, as well as pre-employment testing in industries demanding acute safety.
The EtG hair test provides a 90-day alcohol consumption assessment by detecting ethanol metabolites lodged into the hair structure, offering insights into habitual or chronic use over isolated incidents.
