Quest Diagnostics Incorporated provides diagnostic information services including laboratory testing of blood, urine, and other bodily fluids and tissues for healthcare providers and patients. The company operates laboratories and patient service centers performing routine and esoteric tests ordered by physicians for diagnosis, monitoring, and treatment of diseases. Quest serves physicians, hospitals, employers, health plans, government agencies, and patients through its extensive network. The company provides clinical laboratory testing, anatomic pathology, diagnostic imaging, and other services. Founded in 1967 and headquartered in Secaucus, New Jersey, Quest is one of the two largest clinical laboratory companies in the United States alongside Labcorp. The company benefits from essential healthcare services, scale advantages, managed care relationships, regulatory barriers to entry, and recurring revenue models. Quest experienced elevated COVID-19 testing volumes that have since normalized. The company faces reimbursement pressures from government and commercial payers, competitive markets, regulatory requirements, and the need for continuous investment in testing capabilities and technology. Quest continues to focus on operational efficiency, advanced diagnostic services, data and analytics solutions, and strategic growth to maintain market leadership and deliver shareholder value.
