 LABORATORY CORPORATION OF AMERICA-REGISTERED TRADEMARK- COMPLETES
            ACQUISITION OF BIO-DIAGNOSTICS LABORATORIES

Burlington, NC, April 19, 2000 - Laboratory Corporation of
America-Registered Trademark- Holdings (LabCorp-Registered
Trademark-) (NYSE: LH) today announced that it has completed the
acquisition of certain clinical testing assets of Bio-Diagnostics
Laboratories (BDL). Based in Torrance, California, BDL is the
largest provider of clinical laboratory testing services in the
South Bay area of Los Angeles County.  BDL had annual clinical
revenues in 1999 of approximately $12 million. Terms of the
agreement were not disclosed.

"The combination of LabCorp and BDL will allow us to greatly
enhance our laboratory services in the South Bay area of Los
Angeles as well as expand our presence into northern Orange County,
Long Beach, and Santa Monica," said Richard L. Novak, executive
vice president and chief operating officer of LabCorp.  "This is
LabCorp's second acquisition in Southern California this year, and
further strengthens our market position in that region.  BDL adds
12 patient service centers to our infrastructure in greater Los
Angeles, giving area physicians and hospitals greater access to
LabCorp's leading-edge specialty tests and national information
network."

 Laboratory Corporation of America-Registered Trademark- Holdings
(LabCorp-Registered Trademark-) is a national clinical laboratory
with annual revenues of $1.7 billion in 1999.  With 18,000
employees and over 100,000 clients nationwide, the company offers
more than 2,000 clinical tests ranging from simple blood analyses

expertise in innovative clinical testing technology with three
Centers of Excellence. The Center for Molecular Biology and

Each of the above forward-looking statements is subject to change
based on various important factors, including without limitation,
competitive actions in the marketplace and adverse actions of
governmental and other third-party payors.  Further information on
potential factors that could affect LabCorp's financial results is
