How Urine Drug Testing Works

Urine drug testing remains the predominant choice across Devon, PA and the U.S. for detecting recent substance use. It stands as the exclusive method sanctioned for DOT-regulated evaluations outlined in 49 CFR Part 40. This methodology assesses a urine sample to unveil the presence of drugs, metabolites, or alcohol markers. Urine testing is revered for its systematic, confidential approach, providing indisputably accurate results suitable for employers, personal evaluations, and court-mandated programs.

Testing Methods & Collection Process

  • 1. Donor Identity Verification: Required government identification is produced, and the necessary chain-of-custody documentation is completed by the donor before commencement.
  • 2. Secure Collection Environment: The collection takes place in a controlled restroom environment designed to prevent tampering with added security measures.
  • 3. Chain of Custody Documentation: Utilizes a federally recognized Chain of Custody Form (CCF) to guard the sample's integrity and support its legal defensibility.
  • 4. Temperature & Validity Checks: Immediately after collection, checks for temperature and appearance validate the specimen's authenticity. The laboratory conducts further validity checks, focusing on creatinine levels, pH, specific gravity, and adulterant screening.
  • 5. DOT Split Specimen: DOT tests split specimens into two for primary and disputed analysis, while non-DOT tests generally involve collecting a single vial.
  • 6. Laboratory Screening & Confirmation: Testing at SAMHSA-certified labs follows a two-phase process: initial immunoassay screening followed by confirmatory GC/MS or LC/MS testing.
  • 7. MRO Verification: A licensed Medical Review Officer assesses non-negative findings, ensuring accuracy and discussing with the donor before final decisions.

Expected Timeframes for Urine Test Results:

Benefits of Urine Drug & Alcohol Testing

Nevertheless, urine testing withstands its place as the leading choice for practical, extensive substance assessments across the nation.

How Hair Drug Testing Works

In Devon, PA and beyond, hair drug and alcohol testing serves as a highly consistent laboratory method to reveal long-term substance use patterns. Unlike urine testing focused on recent intoxication, hair testing provides a 90-day insight by assessing drug metabolites embedded within the hair strands. This method is especially beneficial for workplace screening, legal inquiries, child custody cases, and any context demanding a comprehensive view of a person's substance use antecedents.

Testing Methods & Collection Process

1. Donor Identity Verification

The process initiates with the donor showing a valid government ID, followed by the completion of consent and chain-of-custody documents to affirm authentic documentation.

2. Hair Collection Procedure

At collection, a trained professional acquires a minor hair sample, typically comprising 100-120 strands near the scalp. Should scalp hair be unavailable, body hair is an alternative. This immediate, painless procedure occurs under direct oversight.

3. Chain of Custody Documentation

Documentation with a Hair Drug Test Custody and Control Form logs the specimen's acquisition, sealing, and transfer to uphold legality and protect the results during testing.

4. Laboratory Preparation & Analysis

Upon reaching the lab, the hair specimen undergoes comprehensive forensic processes, including:

Following extraction, samples undergo detailed lab testing:

5. Metabolite Detection

Metabolites, trapped within the hair as it grows, offer a stable, enduring record of substance use. Given these internal incorporations, falsifying results or cheating is extremely arduous.

6. MRO Review

Certified Medical Review Officers evaluate non-negative outcomes, confirming test accuracy and scrutinizing possible medical explanations before finalizing the conclusive results.

How Long Do Hair Test Results Take?

Hair testing's multi-layered lab process implies a marginally extended turnaround than urine testing, yet ensures unparalleled detection constancy.

Benefits of Hair Drug & Alcohol Testing

  • 90-day detection window for chronic substance insights.
  • Difficult to decept or corrupt results.
  • Exposes steady, erratic, or ceased substance usage patterns.
  • Optimized for judicial, custody, and compliance requirements.
  • Painless, swift collection process.
  • Utilizes GC/MS or LC/MS for accurate confirmations.

Limitations of Hair Drug & Alcohol Testing

  • Fails to detect recent consumption (within days of intake).
  • Reportedly costlier than urine or fluid tests.
  • Body hair offers non-specific timelines.
  • Substance integration varies with hair type and growth rates.
  • Not applicable for DOT regulatory testing.

Regardless of these limitations, hair testing remains a notable method for verifying long-term substance use, leveraged broadly by employers, legal authorities, and individuals seeking credible, tamper-resistant findings.

Alcohol & Drug Testing-How Each Method Works

At Accredited Drug Testing, we present a diverse array of drug and alcohol screening strategies, each tailored to meet the demands of employers, Department of Transportation (DOT) prescriptions, legal requirements, and personal evaluations. Understanding the nuances of each method is essential for making informed decisions, ensuring trustworthy results, and guaranteeing compliance with federal and Devon, PA state legislation. Our extensive network, certified labs, and skilled Medical Review Officers uphold the precision, credibility, and professionalism crucial for results you can count on.

Alcohol Urine Drug Test

The alcohol urine test is designed to detect recent alcohol intake by tracking ethanol metabolites in the urine. This technique is frequently deployed for workplace testing, court mandates, and following accidents. Although it doesn't measure current impairment, it extends a window of detection for several hours, rendering it a rapid and cost-effective option for monitoring.

ETG Alcohol Test (Urine)

The EtG (Ethyl Glucuronide) urine test offers highly sensitive screening to catch alcohol consumption up to 80 hours post-intake. Due to EtG being a direct digested form of ethanol, this test is ideal for judicial systems, rehabilitation centers, and monitoring bodies. It spans a longer detection window than conventional urine tests and is celebrated for reliability and accuracy.

Breath Alcohol Test

A breath alcohol test determines current intoxication levels by evaluating the alcohol percentage in deep lung air. Utilized with DOT-certified breath alcohol devices (EBTs), it provides immediate and defensible outcomes. This procedure is mandated for DOT-involved staff and commonly employed for workplace checks, accidents, and suspicious behavior cases.

Blood Alcohol Test

The blood alcohol test directly quantifies the ethanol concentration in the bloodstream, representing one of the most precise methods for assessing impairment. Trusted by hospitals, law enforcement, and legal experts, blood alcohol tests are pivotal for DUI situations, emergency scenarios, and high-stakes legal investigations.

PEth Alcohol Blood Test

A PEth (Phosphatidylethanol) blood test identifies habitual or excessive alcohol consumption by detecting biomarkers in red blood cells. Capturing intake up to 2-3 weeks, PEth provides a robust indication of ongoing drinking behavior, invaluable in family law, monitoring regimens, rehabilitation facilities, and pre-employment protocols for safety-focused domains.

ETG Alcohol Test (Hair)

The EtG hair alcohol test spans an expansive 90-day detection period through assessment of alcohol derivatives in hair strands. This technique tracks extensive patterns signifying regular or historical alcohol use instead of isolated consumption instances. Preferred by courts, child custody deliberations, and enduring surveillance schemes for its dependability and precision.

With experienced oversight, accredited laboratories on a national scale, and efficient scheduling, Accredited Drug Testing ensures that each alcohol assessment procedure offers defensible, transparent, and compliant insights, supporting individuals and organizations in maintaining awareness, security, and adhering to regulation rigorosities.


Accredited Drug Testing provides nationwide drug and alcohol screening solutions, including urine, hair, EtG, PEth, and breath alcohol testing.
