Urine drug testing remains the predominant method for screening drugs in the United States, particularly as it is the exclusive approved procedure for DOT-regulated drug testing under 49 CFR Part 40. This technique identifies recent substance intake by examining urine for drugs, metabolites, or alcohol indicators. The method is standardized, ensures confidentiality, and is tailored to deliver precise, legally sound results for employers, individuals, and judicial programs within Northfield, MN and nationwide.
Every donor presents an official ID and completes necessary chain-of-custody paperwork before the test is administered.
Specimens are collected in a regulated restroom setting to deter tampering. Protocols might include limiting personal belongings, securing water sources, and adding dye to toilet water.
Utilizing a recognized Chain of Custody Form (CCF), the sample is meticulously tracked from collection through laboratory analysis, which safeguards its integrity and supports legal defensibility.
Right after collection, specimen temperature and appearance are verified. The laboratory further assesses validity, testing for factors like creatinine levels, pH balance, specific gravity, and the presence of adulterants.
Under DOT standards, urine samples are divided into two separate vials; one for the primary analysis and the second for retesting if needed. Non-DOT tests require only one vial.
At SAMHSA-certified labs, samples undergo a two-tier analysis:
A medical review officer scrutinizes non-negative outcomes, confirms results, and consults donors regarding medical explanations before finalizing results.
Extra time might be required for specific scenarios like shy bladder cases, invalid samples, or additional laboratory and donor follow-up.
Notwithstanding the shorter detection range, urine testing prevails as the most feasible and effective method for screening purposes nationwide.

3. Chain of Custody Documentation
Completion of the Hair Drug Test Custody and Control Form documents the collection, sealing, and transfer of the sample to safeguard its legal defensibility throughout the testing process.

Subsequent laboratory tests include:
5. Metabolite Detection
