About
Laboratory Corporation of America Holdings (Labcorp) is a Burlington, North Carolina-based clinical laboratory and life sciences company — publicly traded on the New York Stock Exchange (NYSE: LH) as an S&P 500 Health Care component — providing diagnostic laboratory testing services for physicians, hospitals, health systems, and patients across the United States and internationally, and providing drug development laboratory services (biopharmaceutical clinical trial laboratory support) through approximately 60,000 employees. In fiscal year 2024, Labcorp reported revenues of approximately $13.1 billion from the Diagnostics segment — following the June 2023 separation of its Drug Development segment as Fortrea Holdings (NASDAQ: FTRE), an independent public company providing CRO (contract research organization) services to pharmaceutical and biotech clients. CEO Adam Schechter has focused the post-Fortrea Labcorp on the pure-play diagnostics business: clinical testing across 6,000+ test menu items (routine blood work, specialty genetic testing, toxicology, and anatomic pathology) processed at Labcorp's 2,000+ patient service centers and sent to regional and specialty reference laboratories for results reporting to ordering physicians. The Labcorp consumer-direct testing initiative (at-home specimen collection kits for STI testing, COVID testing, and other direct-to-consumer tests ordered at labcorp.com without physician referral) expands beyond the traditional physician-ordered testing model to capture the growing consumer health testing market. Labcorp's specialty testing portfolio (oncology genomic profiling, rare disease genetic panels, prenatal cell-free DNA testing, advanced cardiac biomarker panels) generates higher revenue per requisition than routine chemistry and hematology panels — driving mix shift toward specialty and molecular testing revenue.
