Segment Reporting [Abstract]

Summary of Segment Reporting Information by Segment

The following table is a summary of segment information for the three and nine months ended September 30, 2016 and 2015. Segment asset information is not presented since it is not used by the chief operating decision maker at the operating segment level. Operating earnings (loss) of each segment represents net revenues less directly identifiable expenses to arrive at operating income (loss) for the segment. General corporate activities included in the table below are comprised of general management and administrative corporate expenses, amortization and impairment of intangibles assets, other operating income and expenses net of certain general corporate activity costs that are allocated to the DIS and DS businesses and the gains on disposition of businesses associated with the sale of Focus Diagnostics (see Note 6) and the contribution of the Company's clinical trials testing business to the Q² Solutions joint venture in the third quarter of 2015. The accounting policies of the segments are the same as those of the Company as set forth in Note 2 to the consolidated financial statements contained in the Company’s 2015 Annual Report on Form 10-K and Note 2 to the interim unaudited consolidated financial statements.
