EXHIBIT 14

                             CODE OF BUSINESS ETHICS

                         "Integrity is the Bottom Line."

This Code of Business Ethics describes the standards of business conduct
required of all Quest Diagnostics employees, executive officers and directors.
This Code reflects our Company's Vision and Values. No code of conduct can
replace the thoughtful behavior of an ethical director, officer or employee, but
this Code serves to help us focus on key areas of ethical risk, provide guidance
on appropriate behavior, and continue to foster the culture of honesty and
accountability which is evident throughout Quest Diagnostics.

Each employee, officer and director has a personal responsibility to ensure that
his or her actions abide by the letter and the spirit of this Code. Management
must instill a culture in which compliance with the Company's policies and all
applicable laws is at the core of all the Company's business activities.

The policies set forth in this Code are supported by the specific and detailed
policies and practices contained in the Company's Employee Handbook, Integrity
Commitment, Compliance Policy Handbook and Standard Operating Procedures (SOPs).

                                 KEY PRINCIPLES

CONFIDENTIALITY     Quest Diagnostics employees, officers and directors must
                    respect and maintain the confidentiality of confidential
                    information regarding the Company, its services, customers
                    and patients.

                    Officers, directors and employees must maintain the
                    confidentiality of information entrusted to them by the
                    Company, customers or patients of the Company, except when
                    disclosure is authorized or legally permitted or mandated.
                    Confidential information includes all non-public information
                    that might be of use to competitors, or harmful to the
                    Company or its customers, if disclosed. Equally important is
                    safeguarding the confidentiality of the personal information
                    entrusted to us by patients. The obligation to safeguard
                    confidential information continues after employment or board
                    service with the Company ends.

NO CONFLICT OF      Quest Diagnostics employees, officers and directors must
INTEREST            avoid any conflicts of interest that could inhibit their
                    ability to act or make decisions in the best interests of
                    the Company.

                    A "conflict of interest" exists when a person's private
                    interest interferes in any way, or even appears to
                    interfere, with the interests of the Company. A conflict
                    situation can arise when an employee, officer or director
                    takes actions or has personal, financial or other interests
                    that may interfere with his or her ability to perform any of
                    his or her work for the Company objectively and effectively.
                    Conflicts of interest also arise when an employee, officer
                    or director, or a member of his or her family, receives
                    improper personal benefits as a result of his or her
                    position in the Company. An employee who is in any doubt as
                    to whether a conflict of interest exists or would exist in a
                    particular situation should check in advance with the Legal
                    and Compliance Department. No person may engage in an
                    activity that involves a conflict of interest, except with
                    the specific prior approval in writing of the Legal and
                    Compliance Department.

                    Every employee, officer and director who is aware of any
                    activity, financial interest or relationship that may
                    present a possible conflict of interest must report the
                    potential conflict of interest as described in the
                    compliance policy "Duty to Report."









                                             [INTEGRITY IS THE BOTTOM LINE LOGO]


  CORPORATE         Quest Diagnostics employees, officers and directors may not
OPPORTUNITIES       use corporate  property, information or position for
                    personal gain.

                    Employees, officers and directors are prohibited from
                    competing with Quest Diagnostics and owe a duty to the
                    Company to advance the Company's interests to the best of
                    their abilities. Employees, officers and directors who are
                    aware of an opportunity that is generally in the scope of
                    the Company's business must present that opportunity to the
                    Company.

 PROTECTION OF      Quest Diagnostics employees, officers and directors must
COMPANY ASSETS      protect the Company's assets and ensure they are used only
                    for legitimate business purposes.

                    Theft, carelessness and waste have a direct impact on the
                    Company's profitability. Employees, officers and directors
                    are responsible for ensuring that the Company's assets are
                    utilized efficiently and appropriately.

  FAIR DEALING      Quest Diagnostics employees, officers and directors must
                    deal fairly with other employees, customers, patients,
                    vendors and competitors.

                    No person may take unfair advantage of anyone through
                    manipulation, concealment, abuse of privileged or
                    confidential information, misrepresentation of
                    facts or any other unfair-dealing practice.

                    commitment to integrity. Violations will be dealt with

                    establishing and maintaining effective disclosure controls
                    and procedures and internal controls and procedures for

                    their supervisors or other appropriate personnel, including
                    the Legal and Compliance Department, at any time if there is
                    any doubt about the best course of action in a particular
                    situation. No employee will suffer any penalty or
                    retribution for reporting suspected misconduct or
                    noncompliance or will be subject to adverse consequences as
                    a result of making the report.
