Burlington, NC, March  4, 2004 - Laboratory Corporation of America-Registered
Trademark-Holdings (LabCorp-Registered Trademark-) (NYSE: LH) today
announced a definitive agreement with Swedish Medical Center, one of the
largest and most comprehensive not-for-profit health care providers in the
Pacific Northwest, to provide laboratory services to Swedish facilities
through January 31, 2015. Under the terms of the agreement, LabCorp will
extend and expand the existing relationship between its wholly owned
subsidiary, Dynacare Northwest Inc., and Swedish, to provide laboratory
services to all Swedish Medical facilities and its affiliated physician
group. The Swedish Medical hospital system represents approximately 1,300
beds in addition to operating an active patient outreach program.

nation's leading medical centers," said Richard L. Novak, executive vice
president and chief operating officer for LabCorp. "Large hospital systems
such as Swedish need a lab partner that is committed to continually expanding
access to the latest scientific and technological advances in laboratory
medicine. Our full menu of diagnostic testing services, including specialized

medical services to physicians and their patients."
