               QUEST DIAGNOSTICS REPORTS STRONG FINANCIAL RESULTS
                             IN SECOND QUARTER 2004

TETERBORO, N.J., JULY 22, 2004--Quest Diagnostics Incorporated (NYSE: DGX), the
nation's leading provider of diagnostic testing, information and services,
announced that for the second quarter ended June 30, 2004, net income increased
to $135 million, or $1.28 per diluted share, before $13.2 million in special,
pre-tax charges, or $0.08 per share, related to the recently completed CEO
succession process and the company's debt refinancing, both of which had been
previously announced. Including these charges, net income was $127 million, and
earnings per diluted share were $1.20. For the second quarter of 2003, net
income was $120 million and earnings per diluted share were $1.12.

Second quarter revenues grew 6.4% over the prior-year level to $1.3 billion.
Clinical testing volume, measured by the number of requisitions, increased 2.1%,
and revenue per requisition increased 3.7%. The remainder of the revenue growth
was contributed by the company's non-clinical testing businesses.

For the second quarter, operating income, excluding the charge for the CEO
succession process, was $240 million, or 18.5% of revenues, compared to $219
million, or 17.9% of revenues, in 2003. Including the charge, operating income
was $230 million, or 17.7% of revenues. Bad debt expense improved to 4.3% of
revenues, compared to 4.8% a year ago. Days sales outstanding were 47 days,
unchanged from a year ago. Cash from operations increased to $207 million from
$169 million in 2003. During the quarter the company repurchased $226 million of
its common stock and made capital expenditures of $46 million.

"We continued to improve organic revenue growth and expand our operating margin
during the quarter," said Surya N. Mohapatra, Ph.D., President and Chief
Executive Officer. "Our ability to generate strong cash flow enabled us to
repurchase shares and continue investing to differentiate Quest Diagnostics in
the marketplace. These investments have been focused on further improving our
customer service, training our sales force to better communicate the medical
value of new tests and technologies, and expanding the capabilities of our
information technology products. Customers recognize the value of these
investments when they select Quest Diagnostics as their laboratory provider."

For the first half of 2004, excluding the second quarter special charges, net
income increased to $251 million, and earnings per diluted share increased 20%
to $2.38 from $1.98 in 2003. Including the second quarter charges, net income
was $243 million and earnings per diluted share were $2.30. Revenues increased
10.4% to $2.6 billion. Operating income, excluding the charge for the CEO
succession process, was $449 million, or 17.6% of revenues, compared to $382
million, or 16.5% of revenues in 2003. Including the charge, operating income
was $439 million, or 17.2% of revenues. During the first half of 2004, the
company repurchased $271 million in common stock and made capital expenditures
of $91 million.

growth of about 1.5% contributed by Unilab, acquired February 28, 2003.

operations is expected to approximate $700 million, and capital expenditures

Notes to Financial Tables

1)    Net income per common share is computed by dividing net income by the
      weighted average number of common shares outstanding. Potentially dilutive
      common shares primarily represent stock options.

      The following table presents net income and basic and diluted earnings per
      common share, had the Company elected to recognize compensation cost based
      on the fair value at the grant dates for stock option awards and discounts
      granted for stock purchases under the Company's Employee Stock Purchase
      Plan, consistent with the method prescribed by Statement of Financial
      Accounting Standards No. 123, "Accounting for Stock-Based Compensation",
      as amended by Statement of Financial Accounting Standards No. 148,

2)   Other operating expense, net represents miscellaneous income and expense
     items related to operating activities including gains and losses associated
     with the disposal of operating assets. For the three and six months ended
     June 30, 2004, other operating expense, net includes a $10.3 million charge
     associated with the acceleration of certain pension obligations in
     connection with the recently completed CEO succession process.

3)   Interest expense, net for both the three and six months ended June 30,
     2004, includes a $2.9 million charge representing the write-off of deferred
     financing costs associated with the second quarter 2004 refinancing of the
     Company's bank debt and credit facility.

4)   In 2003, the Board of Directors authorized a share repurchase program,
     which permits the Company to purchase up to $600 million of its common
     stock. For the three months ended June 30, 2004, the Company repurchased
     approximately 2.7 million shares of its common stock at an average price of

 5)  Free cash flow represents net cash provided by operating activities less
     capital expenditures. Free cash flow is presented because management
     believes it is a useful adjunct to cash flow from operating activities and
     other measurements under accounting principles generally accepted in the
     United States since it is a meaningful measure of a company's ability to
     fund investing activities and meet its future debt service requirements.
     Free cash flow is not a measure of financial performance under accounting
     principles generally accepted in the United States and should not be
     considered as an alternative to cash flows from operating, investing or
     financing activities as an indicator of cash flows or as a measure of
     liquidity. The following table reconciles net cash provided by operating
     activities to free cash flow:



                                                                          Six Months Ended

6)   Net income before special charges excludes the charges associated with the
     acceleration of certain pension obligations in connection with the recently
     completed CEO succession process and the second quarter 2004 refinancing of
     the Company's bank debt and credit facility. Operating income before
     special charge excludes the charge associated with the CEO succession
     process. Both operating income and net income before special charges,
     including per common share amounts, are presented because management
     believes that it is a useful adjunct to other measurements under accounting
     principles generally accepted in the United States, including reported
     operating income and net income since it is a meaningful measure of the
     Company's on-going operating performance and is on a basis consistent with
     prior reported results. Operating income before special charge and net
     income before special charges, including per common share amounts, are not
     measures of financial performance under accounting principles generally
     accepted in the United States and should not be considered as an
     alternative to reported operating income and net income as an indicator of
     performance. The following table reconciles operating income and net income
     before special charges to reported results:



                                                                      For the Three Months Ended June 30, 2004

7)   Estimated comparable diluted earnings per common share represents
     management's estimate of diluted earnings per common share for the full
     year 2004 before charges associated with the acceleration of certain
     pension obligations in connection with the recently completed CEO
     succession process and the second quarter refinancing of the Company's bank
     debt and credit facility. Estimated comparable diluted earnings per common
     share is presented because management believes it is a useful adjunct to
     estimated diluted earnings per common share and other measurements under
     accounting principles generally accepted in the United States since it is a
     meaningful measure of the Company's ongoing operating performance and is on
     a basis consistent with previous estimates of diluted earnings per common
     share. Estimated comparable diluted earnings per common share is not a
     measure of financial performance under accounting principles generally
     accepted in the United States and should not be considered as an
     alternative to estimated diluted earnings per common share. The following
     table reconciles estimated diluted earnings per common share to estimated
     comparable diluted earnings per common share:
