Urine drug testing reigns as the most popular screening technique throughout Harrison, TN, and indeed, the nation. Serving as the exclusive method sanctioned for DOT-regulated drug testing, this test is conducted in accordance with 49 CFR Part 40 guidelines. By examining a urine sample, this method detects recent consumption of drugs, drug metabolites, or alcohol biomarkers, ensuring a thorough and confidential screening while delivering legally defensible results that are crucial for employers, individuals, and court-ordered programs.
Testing Methods & Collection Process
1. Donor Identity Verification
The procedure commences with the donor presenting an authorized government identification and signing the necessary chain-of-custody form.
2. Secure Collection Environment
Specimens are collected in a controlled setting, securing all water sources and sometimes dying the toilet water, to mitigate any tampering risks and uphold the sample's integrity.
3. Chain of Custody Documentation
A Chain of Custody Form (CCF) is utilized, following the specimen from its collection to the laboratory, ensuring the test's credibility and defensibility.
4. Temperature & Validity Checks
Post-collection, the collector evaluates the specimen's temperature and appearance. Laboratory analyses include validity testing through parameters such as creatinine levels, pH, specific gravity, and adulterant screenings.
5. DOT Split Specimen
For DOT tests, the specimen is divided into Bottle A for primary screening and Bottle B reserved for retesting if initial results are contested. Non-DOT tests generally collect a single sample.
6. Laboratory Screening & Confirmation
7. MRO Verification
A qualified Medical Review Officer (MRO) evaluates any non-negative results, confirming them before releasing the official results.

2. Hair Collection Procedure

3. Chain of Custody Documentation
Completion of a Hair Drug Test Custody and Control Form logs the specimen's collection, sealing, and handling, ensuring the protection and legality of outcomes.
