Urine drug testing is the most prevalent screening technique nationally and remains the sole test sanctioned for DOT-regulated drug assessments in accordance with 49 CFR Part 40. This testing process pinpoints recent substance intake by evaluating a urine sample for drugs, drug byproducts, or alcohol indicators. It's a streamlined, discreet method engineered to deliver accurate and legally sound outcomes for organizations, individuals, and mandated court programs across Nacogdoches, TX.
Testing Methods & Collection Protocol
1. Verification of Donor Identity
Prior to testing, donors must present a valid government ID and complete necessary chain-of-custody directives.
2. Controlled Collection Conditions
Urine samples are collected under controlled conditions to prevent compromise, where personal belongings are typically limited, water access is controlled, and toilet fixtures may be dyed.
3. Documentation for Chain of Custody
The federally-sanctioned Chain of Custody Form (CCF) accompanies samples from collection through laboratory scrutiny, maintaining the test's authenticity and legal defensibility.
4. Temperature & Authenticity Verifications
Immediately post-collection, samples undergo checks for temperature consistency and physical traits, with validity testing in labs assessing creatinine, pH, and potential adulterants.
5. DOT Dual Sample Method
DOT mandated urine tests are segregated into two containers; Bottle A undergoes initial analysis, while Bottle B serves as a backup for additional testing upon donor contestation. Non-DOT testing uses a singular container.
6. Laboratory Screening and Confirmation
Samples are scrutinized at SAMHSA-accredited facilities using a dual-phased approach:
7. MRO Examination
A licensed Medical Review Officer (MRO) evaluates non-negative outcomes, confirms their validity, and possibly consults with the donor for medical interpretations prior to finalizing results.
Additional time may be needed for shy bladder circumstances, invalid samples, or if extra lab confirmation or contact with donor is required.
