QUEST DIAGNOSTICS CLINICAL LABORATORIES, INC.

Quest Diagnostics Clinical Laboratories, Inc. specializes in forensic and compliance-driven clinical laboratory testing services, with deep expertise in drug and alcohol specimen analysis for federal oversight programs. Their core capabilities include high-complexity urinalysis, toxicology screening, chain-of-custody documentation, and laboratory information system integration tailored to government regulatory standards. They deliver accredited testing services under strict chain-of-custody protocols, ensuring defensible results for probation, parole, and human resources compliance programs. Their technical proficiency spans immunoassay confirmation, gas chromatography-mass spectrometry (GC-MS), and data reporting systems compliant with SAMHSA and DOT guidelines, positioning them as a trusted provider for mission-critical substance abuse monitoring. The contractor maintains consistent relationships with the Department of Justice, Court Services and Offender Supervision Agency, and the Department of the Interior, primarily supporting offender supervision, workforce integrity, and internal compliance initiatives. For these agencies, they provide scalable laboratory testing infrastructure to meet court-mandated and administrative requirements, often operating under task orders that demand rapid turnaround, audit-ready documentation, and secure data handling. Their primary industry focus is on miscellaneous ambulatory health care services (NAICS 621999), where they serve as a specialized clinical diagnostics partner for federal agencies requiring legally defensible testing outcomes. While medical laboratories (621511) form a secondary focus, their operational model is distinctly aligned with public safety and regulatory compliance rather than general clinical diagnostics. Quest Diagnostics Clinical Laboratories, Inc. is a corporate entity headquartered in Secaucus, New Jersey, operating under a 2L structure. Though currently holding no formal government certifications, their laboratory operations adhere to CLIA, CAP, and SAMHSA accreditation standards, enabling them to deliver federally recognized testing services. They maintain a focused government market presence, delivering specialized diagnostic solutions to agencies with stringent compliance and forensic reporting needs.
