      LABORATORY CORPORATION OF AMERICA-REGISTERED TRADEMARK- REPORTS
           RECORD SECOND QUARTER RESULTS ON STRONG VOLUME GROWTH

    Growth Strategy Continues to Positively Impact Financial Performance

Burlington, NC, July 19, 2000 - Laboratory Corporation of America-
Registered Trademark- Holdings (LabCorp-Registered Trademark-) (NYSE:
LH) today announced significantly improved results for the quarter
and six months ended June 30, 2000.

Second Quarter Results
- ----------------------
Net sales for the second quarter were $482.4 million, operating
income was $71.3 million, and net income was $32.7 million. This
compares with net sales of $429.5 million, operating income of $42.1
million, and net income of $19.9 million in the second quarter of
1999. Diluted earnings per common share for the quarter were $0.94,
versus $0.56 for the comparable 1999 quarter. The 12.3 percent
increase in net sales is the result of a 9.2 percent increase in
volume and a 3.1 percent increase in price.

Earnings before interest, taxes, depreciation, and amortization
(EBITDA) were $93.1 million for the second quarter, or 19.3 percent
of net sales, versus $63.3 million, or 14.7 percent of net sales, for
the comparable period in 1999.  Days sales outstanding (DSO) for the
quarter improved to 70 days from 72 days at the end of the first
quarter. The balance owed on LabCorp's term loan was reduced to
$522.5 million at the end of the second quarter, from $573.4 million
at the end of 1999, and the balance on its $450 million revolving
line of credit facility remained at zero.  Operating cash flow for
the quarter was $81.4 million, compared to $50.8 million in the
second quarter of 1999.

"LabCorp had another excellent quarter driven by volume and price
increases in all key segments of our business," noted Thomas P. Mac
Mahon, president and chief executive officer.  "We made measurable
gains in generating new business and maintaining existing accounts.
Our focus on increasing managed care and hospital business also
contributed to our success."

Six Month Results - ----------------- For the six-month period ended June 30, 2000, LabCorp generated net sales of $945.1 million, operating income of $128.7 million, and net income of $58.4 million. For the same period in 1999, net sales were $847.4 million, operating income was $76.5 million, and net income $34.0 million. Diluted earnings per common share were $1.71 in the first half of 2000, compared to $0.79 in the 1999 period. The revenue increase of approximately 11.5 percent consists of a 8.6 percent increase in volume and a 2.9 percent increase in price. EBITDA for the first six months of 2000 was $171.4 million, or 18.1 percent of net sales, versus $118.7 million, or 14.0 percent of net sales, for the comparable period in 1999. Operating cash flow was $129.9 million compared to $75.9 million for the comparable period in 1999. "LabCorp's strategy to leverage our national scale with selected acquisitions, increase the number of managed care plans, and expand our genomic testing capabilities is a key component of this success," said Mr. Mac Mahon. "Additionally, our recently announced agreement to acquire National Genetics Institute, Inc. underscores our commitment to strategic growth and technological innovation."
