Item 9. Regulation FD Disclosure.

Kenneth W. Freeman, Chairman and Chief Executive Officer of Quest Diagnostics
Incorporated (the "Company"), is scheduled to speak at the Credit Suisse First
Boston Thirteenth Annual Health Care Conference on November 14, 2001 at the
Arizona Biltmore Resort and Spa in Phoenix, Arizona. To comply with the
Securities and Exchange Commission's Regulation FD, the Company is filing this
report to update all investors on its outlook.

Mr. Freeman will report the following: "Our outlook remains unchanged from the
guidance we provided during our Third Quarter 2001 financial conference call on
October 19, 2001. We remain comfortable with the consensus of analyst
expectations for fourth quarter earnings of $0.48 per diluted share, as reported
by First Call. We continue to expect full year earnings per diluted share before
special items to grow more than 65%. In 2002, we continue to expect to deliver
earnings per share growth in excess of 30%. This increase is before the
additional $0.35 per diluted share we expect to realize from the change in
goodwill accounting that becomes effective on January 1, 2002. We continue to
remain highly confident in our ability to deliver sustainable outstanding
performance for our shareholders."

The statements in this report which are not historical facts or information may
be forward-looking statements. These forward-looking statements involve risks
and uncertainties that could cause the outcome to be materially different.
Certain of these risks and uncertainties are listed in the Quest Diagnostics
Incorporated 2000 Form 10-K and subsequent filings.
