Built for employers that need testing at the worksite
This page is the main service hub for employers that want drug and alcohol testing handled at the worksite, not sent out to a retail clinic. OnSite Employer Testing supports onsite and mobile collection programs for HR teams, DERs, safety managers, operations leaders, and TPA partners that need clean execution and practical scheduling.
Core drug and alcohol services
Mobile and on-site drug testing
For employers that want the collector sent to the workplace, yard, terminal, office, or job site. Mobile and on-site drug testing. Staffing a job fair or recruiting day? Hiring event drug testing.
DOT drug testing
For federally regulated programs that require DOT-compliant collection workflows and documentation. DOT drug testing. Need random pool management or Clearinghouse administration? Consortium & TPA services.
Non-DOT drug testing
For company-policy workplace testing outside the DOT framework. Non-DOT drug testing
Post-accident and reasonable suspicion
For urgent or same-shift events that need clear intake and clean documentation. Post-accident drug testing and reasonable suspicion testing
Random testing programs
For employers that need ongoing testing support across shifts, sites, or pooled rosters. Random drug testing programs
Alcohol and specialty testing options
These modalities answer specific program needs. Some are specialty options—not default replacements for standard urine or DOT workflows. Confirm authorization with your DER, TPA, or policy owner before booking.
| Service | Best for | Note |
|---|---|---|
| Breath alcohol testing | DOT alcohol programs and post-accident alcohol windows | Real-time alcohol result—not a drug screen substitute |
| Oral fluid drug testing | Observed workplace collections when policy authorizes saliva | Not a default swap for every urine or DOT workflow |
| Hair drug testing | Longer lookback hiring or cause-based programs | Specialty modality—confirm panel with your administrator |
| Nail drug testing | Extended lookback when hair is not viable | Specialty modality with different logistics and lab routing |
| Employer blood testing | PEth, occupational health, wellness panels, titers, and employer bloodwork | Employer blood draw coordination—not standard workplace drug testing |
| PEth alcohol testing | Monitoring and legal-adjacent alcohol programs | Blood-based alcohol marker—not a BAT replacement for DOT post-accident |
Occupational health and blood-draw services
TB Gold and titers, heavy metal monitoring, and biometric wellness screenings are grouped here so occupational health content stays organized—separate from core workplace drug-testing programs. See all occupational health services.
How to choose the right page
Employers usually start with one of these questions:
- Do I need mobile/onsite testing?
- Is this DOT or non-DOT?
- Is this urgent?
- Do I need a specialty specimen?
- Is this an occupational health blood-draw program?
Use that framework to open the service page that matches your order. When in doubt, start with mobile drug testing intake and share program type, locations, and urgency.
