ITEM 9. Regulation FD Disclosure.

Burlington, NC, July 7, 2003 - Laboratory Corporation of
America Holdings (LabCorp-Registered Trademark-)
(NYSE: LH) today announced that it has entered into a
marketing and distribution relationship with
Atherotech, a leading cardiodiagnostic company and
specialty reference laboratory, to offer its proprietary
Vertical Auto Profile (VAP-Trade mark-) Cholesterol Test.
The multi-year agreement includes a provision
for the transfer of patented testing technology to
LabCorp, after which, if certain conditions are met,
LabCorp would become the first clinical laboratory
licensed to perform the cardiovascular disease risk
assessment assay within its own national laboratory
system.

This innovative partnership will ensure broader patient
access for Atherotech's VAP Test technology
through LabCorp's extensive sales and distribution
network, while adding an important test to LabCorp's
already broad menu of esoteric assays for cardiovascular
disease.  According to the American Heart
Association, coronary heart disease kills more Americans
than any other illness, and reducing risk factors is
extremely important.  Atherotech's VAP Test is an
expanded cholesterol test designed to improve the
identification of people at risk for heart disease.  It
provides direct, detailed measurements of cholesterol
subclasses that play important roles in the development
of heart disease.

"We are pleased to offer the VAP Cholesterol Test as part
of our broadly available menu of service offerings
for cardiovascular disease," said Myla Lai-Goldman, MD,
executive vice president, medical director and
chief scientific officer for LabCorp.  "Many of our
physician customers have been asking for this valuable
test to help improve patient care. This initial strategic
partnership with Atherotech is significant because it
will increase patient access to important cardiovascular
technology. We also continue to explore additional
opportunities to further expand our relationship with
Atherotech."

"Cardiovascular disease is a major public health problem
affecting nearly 60 million Americans, and the
need for increased access to effective cardiovascular
disease risk assessment tools is clear," said Atherotech
President and Chief Executive Officer Roseanne Varner.
"This new marketing and distribution relationship
with LabCorp allows us to reach significantly more
physicians who need technologies like our VAP Test to
develop appropriate cardiovascular therapies for their
patients."

Atherotech, based in Birmingham, Ala., is dedicated to
improving the prevention, early diagnosis, and
treatment of heart disease and other cardiovascular

the company's VAP Cholesterol Test, the new standard of care
