Urine drug testing is prevalent across the United States as the only approved method for DOT-mandated drug testing under 49 CFR Part 40. This testing modality detects recent drug use by examining a urine sample for drugs, their metabolites, or alcohol biomarkers. It is an industry-standard procedure that ensures confidentiality and accuracy, offering reliable, legally-valid outcomes for employers, individuals, and judicial mandates in Gretna, LA.
Testing Methods & Collection Process
1. Donor Identity Verification
The process commences as the donor presents valid government-issued identification and completes necessary chain-of-custody paperwork prior to testing.
2. Secure Collection Environment
Urine collections occur in a monitored setting to discourage tampering. Personal items may be checked, water sources secured, and toilet water tinted as part of standard security protocols.
3. Chain of Custody Documentation
Using a federally-recognized Chain of Custody Form (CCF) traces the specimen's journey from collection to the lab, upholding the test's integrity and legal validity.
4. Temperature & Validity Checks
Immediately following collection, the specimen's temperature and appearance are inspected. The lab also conducts validity tests, including checks for creatinine, pH, and specific gravity, along with adulterant screening.
5. DOT Split Specimen
DOT-regulated urine samples are divided into two vials: Bottle A for primary examination and Bottle B for retesting in case the donor contests the outcome. For non-DOT tests, a single vial suffices.
6. Laboratory Screening & Confirmation
Samples undergo testing at SAMHSA-certified labs using a dual-phase analysis:
7. MRO Verification
A qualified Medical Review Officer (MRO) checks non-negative results, confirming accuracy and discussing potential medical justifications with the donor before final result issuance.
Additional time may be necessary for shy bladder cases, invalid specimens, or if confirmation testing or donor contact efforts are needed.

Time was running out before my Cdl got downgraded because of a violation I had on clearinghouse. I couldn't find an employer to send me for my return to duty test, but these guys had my test scheduled and done in the same day! They saved my cdl. Thank you again!
