ITEM 7.01. Regulation FD Disclosure

On March 3, 2009, Laboratory Corporation of America® Holdings (LabCorp®) (NYSE: LH) announced the signing of a collaboration agreement with Duke University related to LabCorp’s state-of-the-art Biorepository in Kannapolis, North Carolina.

The collaboration agreement focuses on the operation of the facility, as well as the management of samples deposited by Duke University, and its clients and collaborators, including samples from the MURDOCK study, which is applying modern-day technologies to identify genomic linkages across major chronic diseases and disorders.

LabCorp’s Biorepository is located adjacent to the North Carolina Research Campus (NCRC) in Kannapolis and is a dedicated facility for storage of human biological samples for a wide variety of customers, including academic centers, research organizations, healthcare providers and biotechnology companies. The Biorepository, which is expected to open later this year, will have the capacity to house up to 10 million samples and will offer both a high-security storage environment and on-site nucleic acid and sample preparation capabilities. The Biorepository will be closely linked to Duke University, the David H. Murdock Core Laboratory Building at the NCRC and LabCorp’s network of routine and esoteric laboratories for discovery and commercial testing.
