## Company history

Labcorp traces its roots to Biomedical Laboratories, founded by the Powell brothers in Burlington, North Carolina, in 1969. National Health Laboratories, another predecessor, was formed in 1971. The two lines of the business came together in 1995 when National Health Laboratories merged with Roche Biomedical Laboratories and adopted the Laboratory Corporation of America Holdings name. [28](https://www.labcorp.com/about-us/history)[29](https://www.sec.gov/Archives/edgar/data/920148/0000950130-95-000802.txt)

Labcorp expanded its laboratory-testing network through the acquisition of Dynacare in 2002. Its 2015 acquisition of Covance added drug-development and clinical-research services, and its 2017 acquisition of Chiltern expanded that business. In 2023, Labcorp separated its clinical development and commercialization services business as the independent company Fortrea.
