In the realm of drug screening, urine tests stand out as the most widely applied method nationwide and are exclusively employed for DOT-regulated screenings under the stipulations of 49 CFR Part 40. Through the examination of urine, this test identifies substances or their metabolites, including alcohol markers, indicative of recent usage. Designed with integrity and confidentiality as priorities, this method delivers factual results, serving the needs of employers, private individuals, and legal systems including those in Chicago, IL.
Testing Techniques & Collection Protocol
1. Verification of Donor Identity
Individuals provide proper government identification and complete a series of chain-of-custody endorsements, safeguarding the integrity of the testing procedure from start to finish.
2. Secure Collection Premises
Urine is collected in a meticulously controlled setting to mitigate tampering risks. All personal items are safely set aside, water sources are sealed, and toilets treated with color agents as routine security measures.
3. Chain of Custody Papers
The federal Chain of Custody Form (CCF) meticulously documents the sample's journey from the collection point to the analytic phases at the laboratory, preserving the test's credibility.
4. Temperature and Authenticity Examinations
Post-collection, samplings undergo evaluations for valid temperature and clarity. Laboratory scrutiny further involves testing for levels of creatinine, pH balance, and adulteration indicators.
5. Split Specimen for DOT
For DOT mandates, urine samples are divided into two bottles to verify primary assessments and address disputes. Non-DOT specimens are not subjected to this split process.
6. Analytical Procedures & Confirmation
Surveillance occurs at SAMHSA-certified labs, adhering to a dual-step process:
7. MRO Assessment
A certified Medical Review Officer evaluates atypical results, substantiates their accuracy, and interacts with the donor for potential medical clarifications before results dissemination.
Contingent delays may arise due to factors such as insufficient sample (shy bladder), sample invalidity, or the requirement for further confirmation or donor communication.
Drawbacks of Urine Drug & Alcohol Tests

This process is thus suitably applied across Chicago, IL for long-view substance use evaluation.
