   LABCORP^® EXCLUSIVELY LICENSES YALE TECHNOLOGY FOR NEW
EARLY STAGE OVARIAN CANCER BLOOD TEST

Burlington, NC, February 23, 2006 — Laboratory Corporation of America^® Holdings (LabCorp^®) (NYSE: LH) today announced that it has entered into an exclusive license agreement with Yale University to commercialize the university’s new blood testing technology for epithelial ovarian cancer. Under the terms of the agreement, Yale will receive signing, milestone and royalty fees. Additional terms were not disclosed.

In the United States, epithelial ovarian cancer (EOC) is the fourth most common cancer in women, and the leading cause of gynecologic cancer death. EOC affects approximately 25,000 women each year, and more than 16,000 will die from the disease.

“Ovarian cancer is one of the most difficult cancers to detect, especially in the earliest stages when it is more treatable,” said Myla P. Lai-Goldman, M.D., Executive Vice President, Chief Scientific Officer and Medical Director of LabCorp. “Consistent with our oncology strategy to fulfill unmet medical testing needs, LabCorp continues to dedicate resources to identifying and commercializing tests to help discriminate earlier between disease-free and cancer patients.”

The Yale technology for EOC is based on a collection of known serum proteins associated with cancer biology. Each protein marker is analyzed using a routine ELISA assay, and a straightforward statistical analysis is then performed to score the combined results. In published research*, multiple statistical analyses on preliminary sample sets for a population of 206 women, including 24 patients with early stage (I/II) EOC and 76 with later stage (III/IV) EOC, showed very favorable sensitivity and specificity, as well as positive predictive value. Yale expects to conduct additional clinical studies on the test technology prior to its commercial introduction by LabCorp.
