How Urine Drug Testing Works

Experience the most trusted method of drug testing across Parker, CO - urine testing.

Urine testing is the most adopted nationwide and stands as the sole DOT-approved method under 49 CFR Part 40. This method accurately reveals recent drug use by scanning a urine sample for drugs, metabolites, and alcohol markers. Ensuring processes are highly confidential and standardized, urine testing delivers precise results that uphold legal standards for employers, individuals, and court systems.

Ky Testing Methods & Collection Steps:

Test Result Timelines You Can Count On:

Additional time required for unique situations, confirmations, or if donor contact is needed.

Why Urine Drug & Alcohol Testing Stands Out:

How Hair Drug Testing Works

When looking to understand an individual's prolonged substance use, hair testing emerges as a promising alternative. By decoding the deep-seated drug metabolites within hair fibers, this method reveals a 90-day timeline of usage, as opposed to merely recent consumption captured by urine tests. This reliability makes it highly regarded in Parker, CO for applications such as workplace monitoring, legal disputes, custody evaluations, and other scenarios necessitating historical data on substance use.

Testing Methods & Collection Process

1. Verification of Donor Identity

To initiate the process, donors supply a valid government-issued ID, and comprehensive consent along with the chain-of-custody documentation is ensured, supporting certification and authenticity.

2. Hair Sample Collection

An adept technician collects 100-120 strands of hair close to the scalp area, preferably from the crown. In cases where head hair is unavailable, body hair serves as a suitable substitute. The method, conducted under scrutiny, is both swift and painless.

3. Chain of Custody Documentation

The Hair Drug Test Custody and Control Form is employed to meticulously record every stage from collection to lab analysis ensuring interpretations are bulletproof for legal contexts.

4. Laboratory Preparation & Analysis

At the lab, the specimen navigates a series of forensic examinations:

  • Decontamination: The hair is systematically cleansed to exclude external pollutants like smoke.
  • Segmentation: The hair is either diced or ground to optimize metabolite extraction.
  • Extraction: Chemical processes remove drug metabolites embedded within hair.

Advanced laboratory tests follow, examining hair samples through:

  • Initial Screening: Detecting drug categories via immunoassay.
  • Confirmation Testing: GC/MS or LC/MS is applied for verifying specific substances and their metabolites with pinpoint accuracy.

5. Metabolite Detection

The intrinsic growth and structure of hair capture drug markers, providing hard-to-manipulate evidence of past substance consumption.

6. MRO Evaluation

Upon detection of non-negative results, a qualified Medical Review Officer authenticates and discusses potential medical interpretations before issuing an ultimate report.

Result Completion for Hair Tests

  • Standard Hair Analysis: Results follow 2-3 business days after labs receive samples.
  • Complex or Alcohol Panels (EtG/FAEE): These conclusions typically take 3-5 business days, influenced by panel complexity.

The intricate nature of hair testing extends analysis periods compared to urine screenings, yet yields unparalleled accuracy and detection constancy.

Benefits of Hair Drug & Alcohol Screening

  • Extensive 90-day window allows for historical insight into substance usage.
  • High resistance to tampering or fraudulent alterations.
  • Depicts patterns reflective of habitual or sporadic use, or recent sobriety.
  • Optimal for legal inquiries, child custody assessments, and mandatory compliance checks.
  • Non-invasive, straightforward acquisition process.
  • Further validation achieved via GC/MS or LC/MS precision testing.

Limitations of Hair Drug & Alcohol Testing

  • Ineffective in recognizing recent ingestion (first 5-7 days).
  • Greater expense when contrasted with urine or saliva tests.
  • Body hair cannot pinpoint exact timing.
  • Substance incorporation may differ according to hair type or growth.
  • Not sanctioned for DOT-imposed criteria.

Despite these hurdles, hair analysis continues to champion accuracy in long-term use detection, frequently employed by corporates, the legal sector, and conscientious individuals beyond Parker, CO.

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 Parker, CO 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. Backed by SAMHSA-certified laboratories, DOT 49 CFR Part 40 compliance, and scientifically validated testing technology, our services ensure accurate, defensible, and confidential results for employers, courts, and individuals.
