Exhibit 99.2
                 STATEMENT UNDER OATH OF PRINCIPAL EXECUTIVE OFFICER AND
PRINCIPAL FINANCIAL OFFICER REGARDING FACTS AND CIRCUMSTANCES RELATING TO
EXCHANGE ACT FILINGS

     I, Robert A. Hagemann, state and attest that:

(1)           To the best of my knowledge, based upon a review of the covered
              reports of Quest Diagnostics Incorporated, and, except as
              corrected or supplemented in a subsequent covered report:

                   o  no covered report contained an untrue statement of a
                      material fact as of the end of the period covered by such
                      report (or in the case of a report on Form 8-K or
                      definitive proxy materials, as of the date on which it was
                      filed); and

                   o  no covered report omitted to state a material fact
                      necessary to make the statements in the covered report, in
                      light of the circumstances under which they were made, not
                      misleading as of the end of the period covered by such
                      report (or in the case of a report on Form 8-K or
                      definitive proxy materials, as of the date on which it was
                      filed).

(2)      I have reviewed the contents of this statement with the Audit and
         Finance Committee of Quest Diagnostics Incorporated.

(3)      In this statement under oath, each of the following, if filed on or
         before the date of this statement, is a "covered report":

                   o  the Annual Report on Form 10-K for the year ended
                      December 31, 2001 of Quest Diagnostics Incorporated;

                   o  all reports on Form 10-Q, all reports on Form 8-K and all
                      definitive proxy materials of Quest Diagnostics
                      Incorporated filed with the Commission subsequent to the
                      filing of the Form 10-K identified above; and

                   o  any amendments to any of the foregoing.
