How Urine Drug Testing Works

In the realm of substance screening, urine drug testing stands out as the most prevalent mechanism nationwide, holding sole approval for DOT-mandated drug examinations under regulation 49 CFR Part 40. This method discerns recent drug use by examining urine specimens for drugs, metabolites, or alcohol indicators, and is performed in a manner that is both consistent and private, delivering results that are precise and defensible in legal contexts. Our procedures are especially relevant in Colton, CA.

Testing Methods & Collection Process

  • 1. Donor Identity Verification: Before commencement, donors present a valid government ID and complete requisite chain-of-custody signatures.
  • 2. Secure Collection Environment: Urine is collected in controlled settings to deter tampering; restrictions may apply to personal items, water sources secured, and toilet water dyed as standard security measures.
  • 3. Chain of Custody Documentation: The process utilizes a Chain of Custody Form (CCF) to ensure sample integrity and legal rigor from collection through lab analysis.
  • 4. Temperature & Validity Checks: Post-collection, specimens are checked for correct temperature, appearance, and undergo validity tests, such as creatinine, pH, and adulterant screenings.
  • 5. DOT Split Specimen: For DOT assessments, two vials are prepared: Bottle A for initial analysis, and Bottle B for retests if disputed, whereas non-DOT tests use a single vial.
  • 6. Laboratory Screening & Confirmation: Conducted at SAMHSA-certified labs, the analysis follows a two-phase approach: an initial immunoassay screen for drug classes and confirmation tests via GC/MS or LC/MS for specific substances.
  • 7. MRO Verification: Verified by a certified Medical Review Officer, non-negative findings are scrutinized for accuracy and medical causes before finalizing results.

How Long Do Urine Test Results Take?

Additional processing time may be necessitated by issues like shy bladder, invalid samples, or when verification or contact with the donor arises.

Alcohol Urine Drug Test

Detecting recent alcohol consumption through alcohol urine tests is widespread for workplace assessments, legal stipulations, and post-incident scenarios. Despite not measuring current impairment, its short detection span is efficient and cost-effective for many situations.

ETG Alcohol Test (Urine)

The EtG urine test is more sensitive, identifying alcohol consumption up to 80 hours post intake. Given its reliability, it is often utilized by legal systems, rehab facilities, and compliance entities demanding more extended detection windows.

Breath Alcohol Test

Focusing on current impairment, the breath alcohol test uses DOT-approved devices to measure blood alcohol concentration efficiently. This approach is favored in workplace checks, accident aftermaths, and scenarios where immediate legal results are warranted.

Blood Alcohol Test

The blood alcohol test provides direct measurement of alcohol levels in the bloodstream, appreciated for its accuracy in high-stake scenarios like hospital assessments, DUI situations, and serious legal investigations.

PEth Alcohol Blood Test

Detecting longer-term alcohol behavior, the PEth blood test recognizes specific biomarkers and sustains detection for up to 2-3 weeks, supporting legal and family law cases, and pre-employment checks in sensitive industries.

ETG Alcohol Test (Hair)

This hair test gives a broad overview of up to 90 days of alcohol use history, ferreting out patterns indicative of habitual consumption, making it indispensable in family and legal testing frameworks.
