Their MRO (Medical Review Officer) services include board-certified physicians who handle positive results with appropriate medical expertise.
Operational Considerations: Quest’s enterprise sales model requires volume commitments and annual contracts. Implementation timelines typically span 4-6 weeks due to legal reviews and system setup. Your finance team will need to manage complex invoicing structures with multiple service codes.

Decision Framework
Questions to Ask During Vendor Evaluation
Compliance Capabilities: How does the platform handle adverse action requirements under FCRA? What documentation does your MRO provide for positive results? How do you ensure Chain of Custody integrity?
Technology Integration: Which ATS platforms offer direct API integration versus manual data transfer? How does candidate communication flow through your existing systems? What reporting capabilities support your audit requirements?
Geographic Coverage: Where are collection sites located relative to your candidate population? What backup procedures exist when primary locations are unavailable? How do you handle remote or traveling candidates?
Pricing Transparency: What fees exist beyond per-test costs? How do volume discounts or minimum commitments affect your total cost? What additional charges apply for rush processing or specialized testing?
What to Prioritize Based on Your Program Maturity
New Programs: Focus on implementation speed, compliance automation, and transparent pricing. You need to establish consistent processes without overwhelming your team.
Established Programs: Evaluate integration capabilities, reporting sophistication, and vendor consolidation opportunities. Your priority shifts from setup to optimization.
Mature Programs: Consider specialized testing capabilities, advanced analytics, and strategic partnership potential. You can leverage vendor expertise for program enhancement.
Red Flags to Watch For
Pricing Complexity: Avoid vendors who can’t provide clear, written pricing for your anticipated volume. Complex fee structures often hide significant costs.
Limited Integration: Be wary of solutions requiring manual data entry or file uploads. These create compliance risks and operational inefficiencies.
Weak Compliance Support: Vendors who can’t clearly explain FCRA adverse action processes or DOT compliance requirements may expose your organization to regulatory risks.
FAQ
How long should drug test results take for pre-employment screening?
Standard pre-employment drug tests should return results within 24-72 hours for negative results. Positive results requiring MRO review may take 3-5 business days. Factor these timelines into your offer-to-start scheduling.
What’s the difference between DOT and non-DOT drug testing for employers?
DOT testing follows specific federal requirements for transportation industry positions, including mandatory 5-panel testing, specific collection procedures, and return-to-duty protocols. Non-DOT testing allows more flexibility in panel selection and procedures while following FCRA requirements.
Can drug testing be included in background check packages?
Many vendors offer combined screening packages, but drug testing often involves separate collection appointments and laboratory processing. Evaluate whether integrated billing provides actual operational benefits versus potential complexity.
How do you handle drug test results that require medical review?
Positive drug test results must be reviewed by a qualified Medical Review Officer (MRO) who contacts the candidate to discuss potential medical explanations. Only results confirmed as positive violations by the MRO should influence hiring decisions.
What drug testing compliance requirements apply to all employers?
All employers must follow FCRA adverse action procedures if drug testing influences hiring decisions. Additional requirements vary by industry (DOT, FMCSA), state fair-chance laws, and union agreements. Consult your legal counsel for specific compliance obligations.
