A DOT 5‑panel urine drug screen is a federally mandated test for safety‑sensitive transportation employees. It detects drug metabolites through urinalysis performed at SAMHSA‑certified laboratories and follows strict chain‑of‑custody with Medical Review Officer (MRO) oversight under 49 CFR Part 40.
Five regulated drug classes (multiple substances in each):
• Marijuana (THC): THC/THCA metabolites
• Cocaine: cocaine and benzoylecgonine
• Amphetamines: amphetamine, methamphetamine, MDMA/MDA
• Opioids: heroin (6‑AM), codeine, morphine; certain semi‑synthetic opioids per current federal rules (e.g., hydrocodone, oxycodone)
• Phencyclidine (PCP): PCP metabolites
Applies to roles where impairment could affect public safety, such as commercial drivers, pilots, railroad and transit operators, pipeline workers, and maritime personnel. Turnaround: Negative screens are often available the same day; confirmed results typically post 1–3 business days after the lab receives the specimen.
Price: $70
Expanded 10‑panel urine screen for employers that require broader coverage. Collected with strict chain‑of‑custody and available using DOT‑style procedures upon request. Note: DOT regulations mandate a 5‑panel screen; a 10‑panel is non‑regulated but commonly used for company policies and non‑DOT roles.
Common classes: Amphetamines (incl. methamphetamine), Cocaine, Cannabinoids (THC), Opiates (codeine/morphine; expanded opioids available), Phencyclidine (PCP), Benzodiazepines, Barbiturates, Methadone, plus an additional class such as Propoxyphene or Oxycodone/Oxymorphone (composition may vary by lab and employer policy).
Turnaround: Rapid negatives often same day; lab confirmations typically 1–3 business days after receipt. Results reported with complete documentation. Price: $109
What it is: A Breath Alcohol Test (BAT) is an evidential test that estimates blood alcohol concentration (BAC) from deep-lung breath. It is fast, non-invasive, and produces immediate results.
When it’s used: DOT post-accident, reasonable suspicion/for-cause, return-to-duty, follow-up, and other employer-required screening situations.
How it works: A screening breath test is performed; if required by protocol, a confirmation test is conducted on a DOT-approved evidential breath tester (EBT) after the appropriate waiting period. All steps are documented on the DOT Alcohol Testing Form (ATF).
What it does NOT do: A BAT measures alcohol only. It does not test nicotine (tobacco) or other drugs—those require separate testing panels (urine, saliva, hair, or blood).
Turnaround & documentation: Results are provided during the visit with printed/electronic documentation for your records and regulatory compliance. Employer action thresholds are applied per federal regulations and company policy.
Note: Available for DOT and non-DOT employer programs.
Price: $90
What we manage: Full third-party administration (C/TPA) for DOT-regulated random testing: pool setup and maintenance, statistically valid random selections, notifications, and compliance tracking across modes (FMCSA, FAA, FRA, FTA, PHMSA, USCG as applicable).
How it works: We enroll covered employees, perform periodic random draws at compliant rates for each DOT mode, notify your Designated Employer Representative (DER), coordinate breath alcohol and urine drug collections, and document every step under chain-of-custody.
Deliverables: selection rosters, selection notices, compliance calendar, MIS reporting support, record retention guidance, and audit support. Optional supervisor training and policy templates available.
Note: Also available for non-DOT employer programs (company random pools).
Post‑accident testing establishes whether alcohol or drugs were a factor after a workplace incident. Collections are initiated as soon as practicable to meet policy or regulatory timelines and are documented under strict chain‑of‑custody (Federal Custody and Control Form for DOT) with secure identity verification.
What we perform: Breath Alcohol Test (BAT) using an evidential breath tester, plus a urine drug screen (DOT 5‑panel for regulated roles, or company‑specified panel for non‑DOT). If a rapid screen is used on site, any non‑negative is automatically sent for laboratory confirmation (GC/MS or LC‑MS/MS) with Medical Review Officer (MRO) review before final reporting.
Turnaround & reporting: alcohol results are immediate; drug screen negatives often same day; confirmed non‑negatives typically 1–3 business days after lab receipt. Final documentation is prepared for HR, insurance, and—when applicable—regulatory recordkeeping.
Note: Also performed for non-DOT employer policies and insurance requirements.
Price: $70 (drug screen) • BAT: $90
When to use it: Initiated when a trained supervisor observes specific, contemporaneous indicators of possible alcohol or drug use (appearance, behavior, speech, odor) while the employee is on duty.
What we do: Rapid scheduling and coordination for a Breath Alcohol Test (BAT) and urine drug screen under strict chain-of-custody. We provide documentation templates (observation checklists, narratives) and time-stamped records to support your decision-making and compliance file.
Supervisor readiness: We offer compliant reasonable suspicion training for supervisors so observations are properly documented and actions align with DOT regulations and company policy.
Turnaround: Alcohol results are immediate; confirmed laboratory drug results for non-negatives typically post within 1–3 business days after lab receipt, following MRO review.
Note: Used by DOT and non-DOT employers; documentation and supervisor training recommended for all programs.
Price: $70 (drug screen) • BAT: $90
Compliance note: DOT programs test only the regulated five drug classes. Broader 10‑panel testing is non‑DOT and typically used for employer policies.
A 7-panel oral fluid test is a non-invasive screening method that uses a saliva sample to detect up to seven different classes of drugs or their metabolites. It is widely used by employers for pre-employment, post-accident, and reasonable suspicion testing because it is difficult to tamper with and identifies very recent drug use.
7 drug classes: Amphetamines, Cocaine, Marijuana (THC), Opiates, Phencyclidine (PCP), Benzodiazepines, Barbiturates.
Turnaround: rapid negatives often same day; lab confirmations typically 1–3 business days after receipt with MRO review.
Price: Call for pricing
A broadened urine drug screen for company policies and non‑regulated roles. Collected with documented chain‑of‑custody; DOT‑style collection procedures available on request.
Common classes: Amphetamines (incl. methamphetamine), Cocaine, Cannabinoids (THC), Opiates/Opioids (codeine, morphine; expanded opioids available), Phencyclidine (PCP), Benzodiazepines, Barbiturates, Methadone, and an additional class such as Propoxyphene or Oxycodone/Oxymorphone (panel composition may vary by lab/employer policy).
Turnaround: Many negatives the same day; lab confirmations typically 1–3 business days after receipt. Price: $109
What Non-DOT means: Testing programs for employers and individuals that are not regulated by DOT rules. Panels, collection methods, and procedures can be tailored to your company policy or personal needs while still following strict chain-of-custody and Medical Review Officer (MRO) review for verified positives.
Specimens & panels: Urine (most common) in 5/10/12+ panel configurations; oral fluid and hair options available. Popular add-ons include oxycodone/oxymorphone, fentanyl, benzodiazepines, barbiturates, methadone, buprenorphine, and others. Alcohol screening can be added via breath alcohol test (BAT) when requested.
When it’s used: Pre-employment, random, post-accident, reasonable suspicion (for-cause), return-to-work/duty (non-DOT), annual/periodic, and court or personal testing. Observed collections and same-day scheduling available when policy requires it.
How we handle it: Chain-of-custody documentation (Custody and Control Form), identity verification, secure specimen transfer to accredited labs, and MRO review before any verified positive is released. Specimen validity checks (temperature, pH, creatinine) help detect dilution or adulteration.
Turnaround & reporting: Rapid screens provide preliminary negatives in minutes; lab-based negatives often report in ~1–2 business days. Any non-negative is confirmed by GC/MS or LC–MS/MS with MRO review, typically reporting in ~1–3 business days after lab receipt. Results are delivered securely to your Designated Employer Representative (DER) or directly to you for personal tests.
Policy support: We can align testing to your written policy and provide templates, guidance on panel selection, and documentation standards for consistent, defensible programs.
Rapid urine drug screens deliver near‑instant, preliminary results (often within minutes) by using immunoassay technology—antibody/antigen binding that flags the presence of drug metabolites.
When it’s useful: on‑site hiring, return‑to‑work checks, clinical triage, and other situations where an immediate decision is needed.
Important: any non‑negative rapid result must be sent to a laboratory for confirmatory testing—gas chromatography/mass spectrometry (GC/MS) or liquid chromatography–tandem mass spectrometry (LC‑MS/MS)—with Medical Review Officer (MRO) review before it is considered final or court‑admissible.
Turnaround: negatives in minutes; confirmed lab results for non‑negatives typically 1–3 business days after the specimen is received.
Post‑accident/incident testing documents whether alcohol or drugs were a factor when an event occurs on the job. Collections are performed promptly to meet policy or regulatory timelines and are recorded under a strict chain‑of‑custody (Custody and Control Form) with secure identity verification.
What’s included: Breath Alcohol Test (BAT) using an evidential breath tester, plus a urine drug screen (5‑ or 10‑panel per employer policy). When a rapid screen is used on site, any non‑negative result is automatically sent for laboratory confirmation by GC/MS or LC‑MS/MS with Medical Review Officer (MRO) review before final reporting.
Turnaround & documentation: alcohol results are immediate; drug screen negatives are often same day; confirmed laboratory results for non‑negatives typically post within 1–3 business days after lab receipt. Final reports include complete documentation for HR, insurance, or legal use.
Rapid probation drug screens are quick, initial urine tests used by probation departments to check for drug metabolites. They use immunoassay technology (antibody–antigen binding) to flag the presence of drug classes and can deliver results in minutes.
Confirmation: Any non‑negative rapid result is sent to a certified laboratory for confirmatory testing by GC/MS or LC‑MS/MS. A Medical Review Officer (MRO) evaluates confirmed results to rule out false positives before final reporting (court documentation where applicable).
Collection & validity: Observed or monitored collections help prevent tampering and preserve chain‑of‑custody (Custody and Control Form). Specimen validity checks (temperature, pH, creatinine) are performed to detect dilution or adulteration. Turnaround: negatives in minutes; confirmed results typically post within 1–3 business days after the lab receives the specimen.
Prices: Urine $70 • Hair $145 • Oral fluid $130 • BAT $90 • Urine Alcohol (EtG) $65
Pre‑employment drug screening helps employers make informed hiring decisions and maintain a safe workplace. Tests are collected under a documented chain‑of‑custody and analyzed at accredited laboratories, with Medical Review Officer (MRO) oversight before results are released to the employer.
Panels & options: standard 5‑panel or expanded 10‑panel and specialty add‑ons per company policy. DOT‑style collection procedures available on request for consistency across workforces (non‑DOT testing remains non‑regulated).
Return‑to‑Duty (RTD): for employees returning after a policy violation or treatment, testing is conducted per an employer or program plan (and, when applicable, under a Substance Abuse Professional plan). Observed collections are common, and follow‑up testing schedules may be required to maintain compliance.
Turnaround: negatives typically report quickly; any non‑negative is confirmed by GC/MS or LC‑MS/MS with MRO review, usually 1–3 business days after lab receipt.
Price: Urine $109 • Hair: Call for pricing • Saliva: Call for pricing
Hair follicle drug testing provides a longer detection window than urine, offering a broader view of substance use patterns. A small sample of head hair (about 100–120 strands cut near the scalp) is collected in a strictly documented chain‑of‑custody and analyzed at an accredited laboratory.
What it detects: multi‑class panels commonly include amphetamines (incl. methamphetamine/MDMA), cocaine, cannabinoids (THC), opiates/opioids (e.g., codeine, morphine; expanded opioids available), and PCP; additional classes (e.g., benzodiazepines, barbiturates) may be available per employer policy.
Detection window: typically up to ~90 days using a 1.5‑inch head‑hair specimen (body hair when head hair is unavailable). Note: hair testing does not reliably detect very recent use (last ~1–5 days). Turnaround: many negatives in ~1–2 business days after lab receipt; non‑negatives require confirmation (GC/MS or LC‑MS/MS) and Medical Review Officer (MRO) review before reporting.
Price: $160 (5‑panel)
Random drug and alcohol testing verifies ongoing compliance and deters use. We manage customizable random pools, selection cycles, notifications, and recordkeeping—supporting DOT‑regulated programs or company policy for non‑DOT workforces.
Reasonable Suspicion (For‑Cause): When trained supervisors document specific, contemporaneous observations (appearance, behavior, speech, odor), we coordinate prompt testing (breath alcohol and/or urine drug screen) under documented chain‑of‑custody. If a rapid screen is used on site, non‑negatives are sent for laboratory confirmation by GC/MS or LC‑MS/MS with MRO review before final reporting.
Program support: pool setup or C/TPA coordination, observed collections when required, secure results delivery, and compliant record retention. Turnaround: negatives quickly; confirmed lab results for non‑negatives typically 1–3 business days after receipt.
