FMCS XPRESS LABS Works with Quest Diagnostics

FMCS XPRESS LABS serves as the front-end testing and collection partner for employers, while Quest Diagnostics functions as the certified reference laboratory for specimen analysis.

Here’s how it works, step by step:

FMCS XPRESS LABS coordinates and administers drug testing services for employers, including:

• Scheduling testing (on-site, mobile, or clinic-based)
   
• Determining DOT vs. Non-DOT testing requirements
   
• Ensuring proper test selection (urine, oral fluid, hair, etc.)
   
• Providing trained and qualified specimen collectors
   
• Managing chain-of-custody documentation
   

We are the client-facing compliance partner—handling logistics, communication, and program oversight.

All specimens are collected in accordance with:

• DOT regulations (49 CFR Part 40), when applicable
   
• Applicable state drug testing laws
   
• Industry-standard chain-of-custody procedures
   

Specimen integrity, donor identification, and documentation accuracy are verified at the point of collection.

Once collected, specimens are securely packaged and sent to Quest Diagnostics, a federally certified laboratory, for testing and confirmation analysis.

Quest Diagnostics performs:

• Initial screening
   
• Confirmatory testing (as required)
   
• Laboratory quality control and certification compliance
   

FMCS XPRESS LABS does not perform laboratory analysis—this separation ensures testing remains legally defensible and audit-ready.

Test results are processed through appropriate channels, including:

• Medical Review Officers (MROs), when required
   
• Employer-designated reporting systems
   
• Secure result delivery in compliance with privacy and confidentiality laws
   

FMCS XPRESS LABS assists employers in understanding results, next steps, and compliance obligations—without providing medical or legal advice.

Beyond specimen collection and lab coordination, FMCS XPRESS LABS supports employers with:

• DOT and Non-DOT program management
   
• Random testing coordination
   
• Post-accident and reasonable suspicion testing
   
• Documentation support for audits, workers’ compensation, and unemployment claims
   
• Referrals to qualified partners for policy development and supervisor training when needed
   

In short:
FMCS XPRESS LABS runs the program.
Quest Diagnostics runs the lab.
Employers get compliant, defensible results without the headache.
