Item 5. Other Events

On September 23, 1996, the Registrant entered into the
Fourth Amendment (the "Fourth Amendment") to its credit
agreement dated April 28, 1995 (as amended, the "Credit
Agreement").  The Fourth Amendment modifies the interest
coverage and leverage ratios applicable to the quarters
ending September 30 and December 31, 1996, and will result
in increased interest rate margins on the revolving and term
loan facilities in the Credit Agreement.  The Fourth
Amendment also reduced the Registrant's capital expenditure
limits for the years ending December 31, 1996 and 1997 and
modified the ability of the Registrant to complete
acquisitions in 1996 and the first quarter of 1997.  The
Fourth Amendment is attached as an exhibit hereto and the
text thereof is incorporated in its entirety herein by
reference.

     Agreement, no Default shall exist for purposes of
     this Section 3.02(ii) during the period commencing
     January 1, 1997 through March 31, 1997, solely by
     virtue of Borrower's potential failure to
     maintain, for the four fiscal quarter period
     ending March 31, 1997, the Leverage Ratio
     specified for such period in Section 5.01(i) or
     the Interest Coverage Ratio specified for such
     period in Section 5.01(j) (and Borrower may, if
     all other conditions precedent for a Borrowing are
     satisfied, issue a Notice of Borrowing hereunder),
     provided in each case that, based on financial
     projections and other information then available
     to Borrower, on a pro forma basis, the Leverage
     Ratio for the four fiscal quarter period ending
     March 31, 1997 will not be more than 5.75 to 1.0
     and the Interest Coverage Ratio for the four
     fiscal quarter period ending March 31, 1997 will
     not be less than 2.70 to 1.0, after giving effect
     to such Borrowing and the application of the
     proceeds therefrom.

FOR IMMEDIATE RELEASE

                              
  LABORATORY CORPORATION OF AMERICA ANNOUNCES AMENDMENT TO
                      CREDIT AGREEMENT
                              
     Recapitalization Program Has Full Support of Banks


Burlington, NC, September 27, 1996 -- Laboratory Corporation
of  America  Holdings (LabCorp) (NYSE: LH)  announced  today
that  it  has  successfully negotiated an amendment  to  its
existing  credit  agreement  covering  both  long-term   and
revolving  credit.   As  previously announced,  the  Company
obtained waivers for the quarter ended June 30, 1996 of  two
covenants  contained  in  the  credit  agreement.   The  new
amendment modifies the interest coverage and leverage ratios
applicable to the quarters ending September 30 and  December
31, 1996, and will result in increased interest rate margins
on  the  facilities  through  the  periods  covered  by  the
amendment.

"While  the  amendment will increase our near-term  interest
costs,  it  indicates a solid working partnership  with  our
banks,"  said  Dr.  James  B. Powell,  President  and  Chief
Executive  Officer.  "We now believe we  have  the  support,
flexibility  and  time  necessary  to  develop  a  long-term
capital structure that better reflects the Company's  future
requirements."

The  Company  noted  that 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 the Company's financial results is
included  in  the  Company's Form 10-K for  the  year  ended
December 31, 1995.

Laboratory  Corporation of America Holdings (LabCorp)  is  a
national  clinical  laboratory organization  with  estimated
annualized  revenues of $1.6 billion.  The Company  operates
primary  testing facilities nationally, offering  more  than
1,700 different clinical assays, from routine blood analysis
to   more   sophisticated  technologies.   LabCorp  performs
diagnostic tests for physicians, managed care organizations,
hospitals,  clinics,  long-term care facilities,  industrial
companies and other clinical laboratories.
