How Urine Drug Testing Works

In Clark, SD, urine drug testing represents the most commonly adopted screening technique across the United States and remains the sole approved method for DOT-regulated testing under 49 CFR Part 40. This technique tests for recent substance use by examining urine samples for drugs, drug metabolites, or alcohol biomarkers. It is conducted within standardized guidelines, ensuring privacy while delivering accurate and legally justifiable results suitable for employers, individuals, and court-mandated programs.

Testing Procedures & Collection Process

  • Verification of Donor Identity: The donor must present a valid government-issued ID and finish mandatory chain-of-custody documents before the commencement of testing.
  • Controlled Collection Environment: Urine samples are collected in a controlled restroom to prevent tampering, with personal items restricted, water sources secured, and toilet water colored to prevent sample alteration.
  • Chain of Custody Documentation: The Chain of Custody Form (CCF), federally recognized, meticulously traces the sample from collection to lab, ensuring result integrity and legal viability.
  • Temperature & Validity Checks: Post collection, both specimen temperature and appearance are checked. The laboratory also undertakes validity testing, including checks for creatinine levels, pH, specific gravity, and the presence of adulterants.
  • DOT Split Specimen: For DOT urine testing, samples are divided into two vials - Bottle A for primary testing and Bottle B reserved for retesting if the donor contests the result. Non-DOT tests use a single vial.
  • Laboratory Screening & Confirmation: Samples processed in SAMHSA-certified labs undergo a two-step testing: Initial Immunoassay Screen for detecting drug classes, followed by GC/MS or LC/MS confirmation testing for precise identification.
  • MRO Verification: A certified Medical Review Officer reviews non-negative findings, verifying their accuracy and discussing potential medical reasons with the donor before finalizing and releasing results.
