SECTION 10(a) PROSPECTUS

The documents containing the information specified in Part I of Form S-8 (plan

specified by Securities and Exchange Commission Rule 428(b)(1).  Such documents
need not be filed with the Securities and Exchange Commission either as part of

pursuant to Rule 424.  These documents, which include the statement of
availability required by Item 2 of Form S-8, and the documents incorporated by
reference in this Registration Statement pursuant to Item 3 of Form S-8
(Part II hereof), taken together, constitute a prospectus that meets the

"Securities Act".

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 3. Incorporation of Documents by Reference.

        The Securities and Exchange Commission allows us to "incorporate by
reference" the information we file with them, which means that we can disclose
important information to you by referring to those documents.  The information
incorporated by reference is considered to be part of this Registration
Statement, and information that we file later with the Securities and Exchange
Commission will automatically update and supersede this information.
Laboratory Corporation of America Holdings (the "Company," and sometimes
referred to herein as the "Registrant") incorporates by reference the documents
listed below and any future filings made with the Securities and Exchange
Commission under Sections 13(a), 13(c), 14 or 15(d) of the Securities Exchange
Act of 1934, as amended (the "Exchange Act"):

       December 31, 2003 (File No.1-11353);

(ii)   The Company's Quarterly Report on Form 10-Q for the fiscal quarter ended
       March 31, 2004 (File No.1-11353);

(iii)  The Company's Definitive Proxy Statement dated April 13, 2004;

(iv)   The description of the Company's Common Stock in the Company's
       Registration Statement on Form 8-B (as amended by Amendment No. 1
       thereto dated April 27, 1995) filed on July 1, 1994 under the Exchange
       Act, including amendments thereto and any report filed for the purpose
       of updating such description).

All documents subsequently filed by the Registrant pursuant to Sections 13(a),
13(c), 14 or 15(d) of the Exchange Act, prior to the filing of a post-effective
amendment which indicates that all securities offered hereby have been sold or
which deregisters all securities then remaining unsold, shall be deemed to be
incorporated by reference into this Registration Statement and to be a part
hereof from the date of filing of such documents.

Any statement contained herein or in a document, all or a portion of which is
incorporated or deemed to be incorporated by reference herein, shall be deemed
to be modified or superseded for purposes of this Registration Statement to the
extent that a statement contained herein or in any other subsequently filed
document which also is or is deemed to be incorporated by reference herein
modifies or supersedes such statement.  Any such statement so modified or
superseded shall not be deemed, except as so modified or amended, to constitute
a part of this Registration Statement.

Item 5. Interests of Named Experts and Counsel

     Bradford T. Smith, who has issued the opinion of the Company's Law
Department on the legality of the common stock of the Company offered hereby,
is Executive Vice President, Chief Legal Officer, and Secretary of the Company.
Mr. Smith owns Company Common Stock and restricted Company Common Stock.  He
also holds employee stock options to purchase Company Common Stock.

Item 6. Indemnification of Officers and Directors

     As authorized by Section 145 of the General Corporation Law of the State
Of Delaware ("Delaware Corporation Law"), each director and officer of the
Company may be indemnified by the Company against expenses (including
attorney's fees, judgments, fines, and amounts paid in settlement) actually and
reasonably incurred in connection with the defense or settlement of any
threatened, pending, or completed legal proceedings in which he/she is involved
by reason of the fact that he/she is or was a director or officer of the
Company; provided that he/she acted in good faith and in a manner that he/she
reasonably believed to be in or not opposed to the best interest
of the Company; and, with respect to any criminal action or proceeding, that
he/she had no reasonable cause to believe that his/her conduct was unlawful.
If the legal proceeding, however, is by or in the right of the Company, the
director or officer may not be indemnified in respect of any claim, issue, or
matter as to which he shall have adjudged to be liable for negligence or
misconduct in the performance of his duty to the Company unless a court
determines otherwise.

     Section 102(b)(7) of the Delaware Corporation Law provides that a
corporation may eliminate or limit the personal liability of a director to the
corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director, provided that such provision shall not eliminate or limit
the liability of a director (i) for any breach of the director's duty of
loyalty to the corporation or its stockholders, (ii) for acts or omissions not
in good faith or which involve intentional misconduct or a knowing violation of
law, (iii) for willful or negligent conduct in paying dividends or repurchasing
stock out of other than lawfully available funds, or (iv) for any transaction
from which the director derived an improper personal benefit.  No such
provision shall eliminate or limit the liability of a director for any act or
omission occurring prior to the date when such provision becomes effective.

     Article Six of the Certificate of Incorporation of the Company provides
that no director of the Company shall be personally liable to the Company or
its stockholders for monetary damages for any breach of his fiduciary duty as
director; provided, however, that such clause shall not apply to any liability
of a director (i) for any breach of such director's duty of loyalty to the
Company or its stockholders, (ii) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (iii)
pursuant to Section 174 of the Delaware Corporation Law or (iv) for any
transaction from which the director derived an improper personal benefit.  In
addition, the provisions of Article VII of the Company's By-laws provide that
the Company shall indemnify persons entitled to be indemnified to the fullest
extent permitted by the Delaware Corporation Law.

     The Company maintains policies of officers' and directors' liability
insurance in respect of acts or omissions of current and former officers and
directors of the Company, its subsidiaries, and "constituent" companies
that have been merged with the Company.

24.1        Power of Attorney (included on the signature page to this
            Registration Statement)

Item 9. Undertakings

(a) The undersigned Registrant hereby undertakes:

  (1) To file, during any period in which offers or sales are being made, a
      post-effective amendment to this Registration Statement:

(i) To include any prospectus required by Section 10(a)(3) of the
          Securities Act of 1933;

    (ii)  To reflect in the prospectus any facts or events arising after the
          effective date of the Registration Statement (or the most recent post-
          effective amendment thereof)which, individually or in the aggregate,
          represent a fundamental change in the information set forth in the
          Registration Statement. Notwithstanding the foregoing, any increase or
          decrease in the volume of securities offered (if the total dollar
          value of securities offered would not exceed that which was
          registered), any deviation from the low or high end of the estimated
          maximum offering range may be reflected in the form of prospectus
          filed with the Securities and Exchange Commission pursuant to Rule
          424(b) if, in the aggregate, the changes in volume and price represent
          no more than 20 percent change in the maximum aggregate offering price
          set forth in the "Calculation of Registration Fee" table in the
          effective registration statement; and

    (iii) To include any material information with respect to the plan of
          distribution not previously disclosed in the Registration Statement or
          any material change to such information in the Registration Statement;

Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the
registration statement is on Form S-3, Form S-8, or Form F-3, and the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the
Securities and Exchange Commission by the Registrant pursuant to Section 13 or
Section 15(d) of the Securities Exchange Act of 1934 that are incorporated
by reference in the Registration Statement;

  (2) That, for the purpose of determining any liability under the Securities
      Act of 1933, each such post-effective amendment shall be deemed to be a
      new registration statement relating to the securities offered therein,
      and the offering of such securities at that time shall be deemed to be
      the initial bona fide offering thereof; and

  (3) To remove from registration by means of a post-effective amendment any of
      the securities being registered which remain unsold at the termination of
      the offering.

(b) The undersigned Registrant hereby undertakes that, for the purposes of
    determining any liability under the Securities Act of 1933, each filing of
    the Registrant's annual report pursuant to Section 13(a) or Section 15(d)
    of the Securities Exchange Act of 1934 (and, where applicable, each filing
    of an employee benefit plan's annual report pursuant to Section 15(d) of
    the Securities Exchange Act of 1934) that is incorporated by reference in
    the Registration Statement shall be deemed to be a new registration
    statement relating to the securities offered therein, and the offering of
    such securities at that time shall be deemed to be the initial bona fide
    offering thereof; and

(c) Insofar as indemnification for liabilities arising under the Securities Act
    of 1933 may be permitted to directors, officers and controlling persons of
    the Registrant pursuant to the foregoing provisions, or otherwise, the
    Registrant has been advised that in the opinion of the Securities and
    Exchange Commission such indemnification is against public policy as
    expressed in the Securities Act of 1933 and is, therefore, unenforceable.
    In the event that a claim for indemnification against such liabilities
    (other than the payment by the Registrant of expenses incurred or paid by a
    director, officer or controlling person of the Registrant in the successful
    defense of any action, suit or proceeding) is asserted by such director,
    officer or controlling person in connection with the securities being
    registered, the Registrant will, unless in the opinion of its counsel the
    matter has been settled by controlling precedent, submit to a court of
    appropriate jurisdiction the question whether such indemnification by it
    is against public policy as expressed in the Securities Act of 1933 and
    will be governed by the final adjudication of such issue.




SIGNATURES

Pursuant to the requirements of the Securities Act of 1933, the Registrant
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form S-8 and has duly caused this Registration
Statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the City of Burlington, State of North Carolina, on this 26th
day of May, 2004.
