Item 3.   Source and Amount of Funds or Other Consideration

          LabCorp agreed to acquire Dynacare (the "Acquisition") pursuant to the
          Pre-Merger Agreement dated as of May 8, 2002 (the "Pre-Merger
          Agreement"), by and among LabCorp, Dynacare and a wholly-owned
          subsidiary of LabCorp, and subject to the conditions set forth
          therein. As an inducement for LabCorp to enter into the Pre-Merger
          Agreement and in consideration thereof, certain executive officers,
          directors and stockholders of Dynacare named on Schedule II
          (collectively, the "Stockholders") entered in a Stockholder Agreement
          (collectively, the "Stockholder Agreements") with LabCorp. Pursuant to
          the Stockholder Agreements, each Stockholder has agreed to vote the
          Dynacare Common Stock it owns in favor of the Acquisition and against
          competing proposals, and to grant LabCorp, upon request, a proxy with
          respect to its Dynacare Common Stock. Pursuant to the Stockholder
          Agreements, each Stockholder has also granted LabCorp an option to
          purchase its shares of Dynacare Common Stock for a purchase price per
          share equal to the merger consideration per share of Dynacare Common
          Stock. The Stockholder Agreements cover an aggregate of 10,495,192
          shares of Dynacare Common Stock owned by the Stockholders. In
          addition, the Stockholder Agreements cover any additional shares
          acquired upon exercise of options held by such Stockholders. A form of
          the Stockholder Agreement is filed herewith as Exhibit 99.1 and
          incorporated herein by reference.

Item 4.   Purpose of Transaction

          On May 8, 2002, LabCorp, Dynacare and a wholly-owned indirect
          subsidiary of LabCorp entered into the Pre-Merger Agreement. Following
          the Acquisition, Dynacare will be amalgamated with and into the
          wholly-owned subsidiary of LabCorp as a result of which holders of
          Dynacare Common Stock will receive 0.1164 shares of LabCorp's common
          stock and $11.50 in cash for each share of Dynacare Common Stock
          outstanding at the time of the Acquisition. The Acquisition which is
          expected to close in the second or third calendar quarter of 2002, is
          contingent on the fulfillment of certain conditions in the Pre-Merger
          Agreement including, but not limited to, all required regulatory
          approvals, and the approval of the Acquisition by the securityholders
          of Dynacare. The Stockholder Agreements are intended to enhance the
          likelihood of timely approval of the Acquisition by Dynacare's
          securityholders.

Item 5.    Interest in Securities of the Issuer

     (a)-(b)As of May 8, 2002, the shares subject to the Stockholder Agreements
          consisted of 10,495,192 shares of Dynacare Common Stock, representing
          approximately 48.2% of the total number of issued and outstanding
          shares of Dynacare Common Stock on May 8, 2002. The 10,495,192 total
          includes options to purchase 1,246,859 shares of Dynacare Common Stock
          that are exercisable within sixty days from the date hereof. The
          10,495,192 total



                                                                     Page 5 of 8

          excludes 105,000 shares subject to options held as of the date of the
          Stockholders Agreements that are not exercisable within sixty days of
          the date hereof. The percentage of 48.2% is calculated based on
          19,326,946 shares of Dynacare Common Stock outstanding as of May 8,
          2002, plus 2,343,756 shares subject to exercisable options.

          By virtue of the Stockholder Agreements entered into with each person
          identified on Schedule II, LabCorp may be deemed to have the right to
          acquire voting and dispositive power over the shares subject thereto
          because the Stockholder Agreements grant LabCorp the right to (i)
          require that the Stockholder give a proxy to LabCorp upon request to
          vote those shares in favor of the Acquisition and (ii) acquire those
          shares; however, LabCorp is not entitled to any other rights as a
          stockholder of Dynacare with respect to the shares of Dynacare Common
          Stock covered by the Stockholder Agreements. LabCorp disclaims
          membership in any group consisting of one or more persons listed on
          Schedule II and disclaims beneficial ownership of any shares
          beneficially owned by any such persons. The filing of this Schedule
          13D shall not be deemed as an admission that LabCorp is the beneficial
          owner of any shares owned by any persons listed on Schedule II or a
          member of any group consisting of such persons.

     (c)  Except as described in this Schedule 13D, there have been no
          transactions in the shares of Dynacare Common Stock effected by
          LabCorp or, to the best of LabCorp's knowledge, any person identified
          in Schedule I of this Schedule 13D, during the last sixty days.

     (d)  Not Applicable.

     (e)  Not Applicable.

Item 6.   Contracts, Arrangements, Understandings or Relationships with Respect
          to Securities of the Issuer

          Except as described in this Schedule 13D and to the best of LabCorp's
          knowledge, there are no contracts, arrangements, understandings, or
          relationships (legal or otherwise) among the persons named in Item 2
          and between such persons and any person with respect to any securities
          of Dynacare.

Item 7.   Material to Be Filed as Exhibits

Exhibit 99.1 Form of Stockholder Agreement between LabCorp and the other
             Stockholders identified in Schedule II hereto.

Exhibit 99.2 Form of Stockholder Agreement between GTCR and LabCorp.
