How Urine Drug Testing Works

As the top choice nationwide, urine drug tests serve as the standard, federally accepted method for DOT-mandated screenings, specifically under 49 CFR Part 40. Urine testing highlights recent drug or alcohol consumption by evaluating a sample's drug presence, metabolites, or alcohol markers. Crafted for precision and privacy, it delivers reliable, legally secure outcomes tailored for businesses, legal obligations, or personal inquiries in Constantine, MI.

Process & Collection Techniques

  • Identity Verification: Participants display an official ID and sign the necessary chain-of-custody documents pre-test.
  • Secure Collection: Collected in regulated spaces to curtail interference, securing personal items, sealing water outlets, and coloring restroom water.
  • Chain of Custody: The standardized Chain of Custody Form trails the sample from collection to testing, safeguarding its legal standing.
  • Validity Checks: Once taken, specimens are assessed for temperature and appearance, with labs further executing validity checks including creatinine, pH, and adulterant screens.
  • DOT Split Specimen: DOT evaluations divide samples into two, enabling retests if needed; non-DOT tests use a single vial.
  • Laboratory Confirmation: With SAMHSA-certified labs, the dual-phase screenings use Immunoassay for initial detection and GC/MS or LC/MS for precise confirmation.
  • MRO Review: A qualified Medical Review Officer validates results, engaging with donors on non-negative findings before releasing them.

Urine Test Result Timeline

  • Instant Results: Negative findings available swiftly; positive samples undergo additional lab verification within 24-72 hours.
  • Standard Lab Tests: Most negative outcomes procured in 24-48 hours.
  • DOT Assessments: Delivered in 1-3 business days based on MRO scrutiny.
  • EtG Alcohol Evaluation: Generally processed between 24-48 hours.
Additional delays may occur due to shy bladder, invalid samples, or confirmation retakes.

Advantages of Urine Analysis

Urine Testing Limitations

Despite limitations, urine testing remains the primary and most critical means employed for substance evaluations.

How Hair Drug Testing Works

When it comes to pinpointing prolonged substance use, hair drug and alcohol testing offers an unparalleled laboratory method. Unlike urine testing's focus on recent consumption, hair testing presents an extensive 90-day detection capability by analyzing drug metabolites housed within the hair shaft. This method serves essential uses in workplace protocols, legal proceedings, child custody evaluations, and any scenario necessitating insight into an individual's prolonged substance use.

Testing Methods & Collection Process

  • 1. Donor Identity Verification: Collection begins post-presentation of a government-issued ID, with complete consent and chain-of-custody documented to uphold legal standards.
  • 2. Hair Collection Procedure: A professional collector acquires a portion of hair, typically 100-120 strands, clipped near the scalp, with the crown region preferred. Absent cranial hair, body hair serves as an alternative. The procedure is swift, painless, and conducted under attentive oversight.
  • 3. Chain of Custody Documentation: Completion of a Hair Drug Test Custody and Control Form assures documentation of specimen acquisition, sealing, and conveyance, safeguarding legal defensibility and process protection.
  • 4. Laboratory Preparation & Analysis: Several forensic steps encompass lab analysis:
    • Decontamination: Hair undergoes washing to remove external impurities or exposures.
    • Cutting/Grinding: Segmentation/pulverization of hair for extraction readiness.
    • Extraction: Chemical extraction of drug metabolites from the hair.
  • Samples are subjected to advanced testing:
    • Initial Screening: Utilizes immunoassay techniques for drug class identification.
    • Confirmation Testing: Implements GC/MS or LC/MS for drug/metabolite specificity with scientific accuracy.
  • 5. Metabolite Detection: As hair grows, drug metabolites become embedded within the hair, documenting substance use history. This binding makes detection impervious to tampering or evasion.
  • 6. MRO Review: A Medical Review Officer reviews all non-negative results to validate accuracy, explore medical explanations, and issue a final official determination.

How Long Do Hair Test Results Take?

  • Standard Hair Test: Results within 2-3 business days once the lab receives the sample.
  • Complex Panels or Alcohol Testing (EtG/FAEE): Results in 3-5 business days subject to the panel.

Though results take longer than urine tests, the rigorous procedure ensures enduring reliable detection.

Benefits of Hair Drug & Alcohol Testing

  • 90-day detection window documenting substance consumption patterns.
  • Extremely challenging to deceive or manipulate.
  • Maps consistent, intermittent, or discontinued drug usage patterns.
  • Highly suited for legal, custodial, and compliance monitoring.
  • Non-invasive, brief collection method.
  • Exceptionally precise corroboration via GC/MS or LC/MS testing.

Limitations of Hair Drug & Alcohol Testing

  • Does not disclose recent drug/alcohol use (5-7 days post-consumption).
  • Costlier than urine/oral fluid evaluations.
  • Inexact timeframe for body hair sample detection.
  • Anomalous integration of substances by hair type/growth rate.
  • Not utilized or recognized for DOT stipulations.

Notwithstanding such constraints, hair analysis is esteemed amongst employers, legal experts, and individuals for tamper-proof and accurate long-term diagnostics.

Alcohol & Drug Testing-How Each Method Works

Accredited Drug Testing offers an extensive array of alcohol and drug testing choices, crafted for compliance across employer, DOT, legal, and personal testing requisites, inclusive of facilities in Constantine, MI. Familiarity with each methodology ensures precise option selection, credible results, and adherence to both federal and state regulations. Our expansive national framework, accredited laboratories, alongside experienced Medical Review Officers provide the exactitude, reliability, and professionalism indispensable for trustworthy testing determinations.

Alcohol Urine Drug Analysis

An alcohol urine analysis discerns recent alcohol intake by pinpointing ethanol metabolites within urine samples. Widely recognized for workplace assessments, legal requirements, and post-incident evaluations, even in Constantine, MI, this method neither measures current impairment nor extends a long detection scope, nevertheless provides an instantaneous, cost-efficient screening solution.

ETG Alcohol Evaluation (Urine)

The EtG (Ethyl Glucuronide) urine assessment is an acute sensing technique capable of detecting alcohol use as long as 80 hours post-consumption. With EtG emerging as a direct ethanol metabolite, this test is prominently utilized by courts, rehabilitation endeavors, and compliance oversight frameworks, delivering an extended detection span compared to conventional urine-based alcohol evaluations, praised for its reliability and accuracy.

Breath Alcohol Assessment

An alcohol breath analysis determines ongoing impairment levels through the assessment of breath alcohol concentration. Administered using DOT-certified breath alcohol determination devices (EBTs), they yield prompt, legally sustainable outcomes. Breath analysis is mandated for DOT-covered workforce, leveraged prevalently in workplace, incident-oriented, and reasonable suspicion testing situations.

Blood Alcohol Analysis

A blood alcohol analysis directly gauges ethanol concentration within the bloodstream, ranking among the most precise methodologies for impairment determination. Hospitals, law enforcement, and judicial institutions rely on this method for its accuracy, prominently applied during DUI assessments, emergency responses, and intricate legal investigations.

PEth Alcohol Blood Test

The PEth (Phosphatidylethanol) blood analysis identifies biomarkers within red blood cells indicating prolonged or intense alcohol consumption. PEth can trace alcohol use margins up to 2-3 weeks and is viewed as a stalwart indicator for extended drinking behaviors, frequently employed in family law rulings, monitoring schemes, treatment hubs, and pre-employment evaluations concerning safety-sensitive sectors.

ETG Alcohol Hair Testing

An EtG hair alcohol examination extends a 90-day observance scale by analyzing alcohol residues embedded within the hair core, discerning recurrent or ongoing alcohol usage paradigms over sole instance consumption. Vital for courts, child custody engagements, and sustained supervision agendas, hair EtG assays command recognition owing to their precision, authenticity, and resistance to short-term abstinence maneuvers.

Through expert navigation, accredited national labs, and efficient scheduling capabilities, Accredited Drug Testing certifies that each alcohol examination method imparts explicit, defensible, and statutory compatible outcomes, aiding individuals and employers to remain informed, safeguarded, and regulatory compliant.


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.
