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 Marksville, LA.

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.
