Urine drug tests are favored nationwide and stand as the only type endorsed for DOT-regulated testing under 49 CFR Part 40. This approach reveals recent substance use by examining a urine sample for the presence of drugs, metabolites, or alcohol markers. The procedure is designed to be uniform, discreet, and ensures precise, legally defendable results suitable for employers, individuals, and judicial programs.
Testing Techniques & Procedure
1. Identity Confirmation of Donor
The donor must present a government-issued ID and complete chain-of-custody documentation prior to the test initiation.
2. Controlled Collection Environment
Specimen collections occur in a supervised restroom setting to minimize alterations. Restrictions are placed on personal items, and water sources are safeguarded, with water in the toilet stained as added preventive steps.
3. Chain of Custody Protocol
Usage of a recognized Chain of Custody Form (CCF) ensures the specimen's integrity and legal standing from collection through lab analysis.
4. Temperature and Validity Assessment
Specimen evaluation includes immediate temperature checks, while the lab executes validity tests, assessing creatinine, pH, specific gravity, and screening for adulterations.
5. DOT Split Specimen Method
DOT processes involve dividing urine into two vials; the primary is Bottle A, and Bottle B is reserved for retest if contested by the donor. Non-DOT samples are not split.
6. Laboratory Examination & Confirmation
Testing is performed in SAMHSA-certified labs following a dual-step protocol:
7. Medical Review Officer (MRO) Assessment
MROs evaluate non-negative outcomes, ensuring accuracy and discussing with donors before finalizing the report.
