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 DeRidder, LA.
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.
Limitations of Urine Drug & Alcohol Testing
Urine testing, notwithstanding its constraints, is still the most feasible and widely embraced approach for drug and alcohol testing across the nation.
Hair drug and alcohol testing is recognized as a highly trusted laboratory technique for identifying long-standing substance use habits. Contrary to urine testing, which detects recent consumption, hair testing extends a substantial 90-day detection period by examining drug metabolites ingrained within the hair fiber. This distinctive capability makes it an apt choice for employment testing, legal disputes, child custody evaluations, and any circumstance necessitating a prolonged assessment of personal substance use history.
Testing Methods & Collection ProcessThough laboratory processing entails a slightly extended timeframe compared to urine testing, the unparalleled consistency achieved via hair testing is noteworthy.
Despite certain downsides like inability to detect very recent use and a higher cost, hair testing prevails as a consistently reliable choice, heavily employed by employers, legal entities, and individual applicants pursuing accurate, tamper-resistant results.
At Accredited Drug Testing, our provision of comprehensive alcohol and drug screening solutions is unmatched, each meticulously crafted to satisfy needs for employers, DOT standards, legal prerequisites, and private testing across DeRidder, LA and the whole nation.

Our broad network, certified labs, and skilled Medical Review Officers uphold the necessary precision, dependability, and professionalism essential for reliable testing results.
An alcohol urine test identifies recent alcohol intake by tracing ethanol byproducts in urine samples and is regularly employed in workplaces, legal orders, and post-incident settings. Though it doesn't determine present intoxication, it offers a prompt, cost-efficient detection timeframe over a few hours, making it ideal for swift screenings.
The EtG (Ethyl Glucuronide) urine test exhibits utmost sensitivity, able to observe alcohol use up to 80 hours post-consumption. Given its association with the ethanol metabolite, courts, rehabilitation camps, and compliance overseers, prefer this method for its extended detection range compared to typical urine tests, renowned for accuracy and dependability.
A breath alcohol test examines current impairment by capturing alcohol concentration in deep lung air. These tests employ DOT-sanctioned breath analyzers (EBTs) for immediate, defensible results. Breath testing is obligatory for DOT-regulated employees, frequently applied in workplaces, post-accident evaluations, and reasonable suspicion situations.
A blood alcohol test accurately gauges the ethanol content in the bloodstream and is lauded for its precision, frequently relied upon by medical facilities, law enforcement, and legal professionals especially critical in DUI scenarios, emergency response, and high-stakes legal inquiries.
The PEth (Phosphatidylethanol) blood test pinpoints lasting or intense alcohol consumption by isolating alcohol-indicative biomarkers inside red blood cells. With the ability to detect activity up to weeks later, PEth is considered a central factor to confirm sustained drinking behavior, utilized in family law, monitoring, recovery centers, and safety-critical employment screenings.
The EtG hair alcohol test enjoys a 90-day detection reach, by dissecting alcohol metabolites embedded inside the hair cuticle. It traces repeated or ongoing alcohol usage rather than transient consumption. Judicial systems, custody battles, and extensive observation programs appreciate hair EtG testing for its consistency, accuracy, and resistant properties to feigned short-term abstinence.
Through expert advice, profitable, certified laboratories, and rapid scheduling, Accredited Drug Testing ensures every alcohol screening method delivers defensible, coherent, and regulation-abiding results, supporting individuals and employers in maintaining security, assurance, and comprehensive statutory conformity.

This is by far the easiest way to get my lab work ordered and paid for. The phone calls are short and to the point. They don’t try to push extra sales on you and when I walk in to the clinic I simply show my donor pass and with in a matter of minutes I’m done. I will continue to use ADT in the future.
