EXHIBIT 99.1

SFAS No. 142 Disclosures

In June 2001, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards ("SFAS") No. 142, "Goodwill and Other
Intangible Assets."  SFAS No. 142 revises the accounting for goodwill
to eliminate amortization of goodwill after December 31, 2001.  The
statement requires an annual assessment of goodwill for impairment and
more frequent assessments if circumstances indicate a possible
impairment.  In the second quarter of 2002, Dianon Systems, Inc.
completed the initial test for impairment and determined that no
goodwill impairment had occurred.  The following table provides a
reconciliation for the prior year's reported net income to adjusted
net income had SFAS No. 142 been applied as of the beginning of fiscal
2001 for the year ended December 31, 2001.
