ITEM 7.01. Regulation FD Disclosure

On August 6, 2008, Laboratory Corporation of America® Holdings (LabCorp®) (NYSE: LH) announced the launch of a national effort to combat chronic kidney disease (CKD) in North America. U.S. Senator Elizabeth Dole (R-NC), a supporter of newly passed legislation to fight CKD, and representatives of the National Kidney Foundation are joining executives of LabCorp at the Kannapolis, NC event today announcing the new initiative.

The cornerstone of the effort is a program offered by LabCorp’s Litholink subsidiary that provides highly nuanced, patient-specific clinical guidance to physicians based on the National Kidney Foundation’s Kidney Disease Outcome Quality Initiative (KDOQI). This program is designed to support nephrologists as well as internal medicine, family practitioners, general practitioners, nurse practitioners and all other healthcare professionals who provide primary care to patients.
