- Quest Diagnostics Incorporated (NYSE: DGX) provides diagnostic information services, including routine, non-routine, and advanced clinical laboratory testing; anatomic pathology testing; and related healthcare insights derived from one of the world's largest clinical lab databases. The company offers an industry-leading menu of tests across specialties such as endocrinology, immunology, neurology, oncology, infectious diseases (including COVID-19 molecular and serology testing, tuberculosis via T-SPOT.TB and Quantiferon, and tick-borne diseases via Accutix), drug monitoring and toxicology (as the largest U.S. workplace drug testing provider for urine, hair, and oral fluid specimens), cardiovascular diagnostics through its CardioIQ and Cleveland HeartLab offerings at the Cardiometabolic Center of Excellence, and cancer diagnostics via QuestVantage; it also delivers employer population health services like biometric screenings and flu shots, Quanum health IT solutions for data analytics and clinician connectivity, population health tools including Quest Lab Stewardship for test optimization and extended care services such as bone density exams and home collection kits, and pharmaceutical support encompassing clinical trials testing, companion diagnostics development, and Quest Clinical Trials Connect for patient recruitment. Operations span a nationwide network of full-service and rapid-response laboratories, over 2,000 patient service centers, mobile phlebotomists, and in-house experts providing consultation; the company serves one in three adult Americans and half of U.S. physicians and hospitals annually, with additional reach through the Global Diagnostic Network in countries including Puerto Rico, Mexico, Brazil, and Canada.
Founded in 1967 as Metropolitan Pathology Laboratory in New York City and headquartered in Secaucus, New Jersey, Quest Diagnostics spun off from Corning in 1996 as an independent public company and employs nearly 50,000 people. It targets physicians, hospitals, employers, health plans, integrated delivery networks, and pharmaceutical firms across segments like general clinical testing, esoteric and gene-based assays, wellness services, and advanced diagnostics for chronic and infectious diseases.
Recent developments include the 2023 acquisition of Haystack Oncology to integrate sensitive minimal-residual disease (MRD) liquid biopsy technology for solid tumor cancer detection into its portfolio, with services launching in 2024; the acquisition of select assets from Steward Health Care's outreach lab services in early 2024 to expand access; the May 2024 agreement to acquire PathAI Diagnostics, enhancing AI-powered digital pathology capabilities for faster cancer diagnosis, quality improvement, and extension into dermatopathology, gastrointestinal, and urological areas; and the 2024 announcement to acquire LifeLabs, Canada's leading diagnostics provider, from OMERS Infrastructure to broaden North American operations and advanced testing access. In 2022, the company acquired Pack Health to bolster patient engagement services for pharma clients and population health, alongside collaborations like retinal imaging with IRIS for diabetic retinopathy screening. These moves strengthen Quest's leadership in oncology, AI innovation, and geographic expansion amid a focus on data-driven insights and preventive care.
