Item 5.03. Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year

On February 11, 2009, Quest Diagnostics Incorporated (the “Company”) amended its Amended and Restated By-Laws (the “By-Laws”) effective immediately, to add a new Section 2.03 which provides for majority voting in director elections. Previously, the By-Laws were silent with respect to the standard of voting in director elections, so plurality voting, the default standard under Delaware law, applied. Under new Section 2.03, in elections that are not “Contested Elections,” directors will be elected by a majority of the votes cast; in Contested Elections, directors will be elected by a plurality of the votes cast. A “Contested Election” is one in which the number of nominees exceeds the number of directors to be elected.

A copy of the By-Laws is attached as Exhibit 3.1 to this Current Report on Form 8-K and is incorporated herein by reference in its entirety.

Item 9.01. Financial Statements and Exhibits

3.1	Amended and Restated By-Laws of Quest Diagnostics Incorporated, as amended effective February 11, 2009.
