PROXY STATEMENT
for
Annual Meeting of Shareholders to be Held on May 4, 2004

GENERAL

      The enclosed proxy is solicited by the Board of Directors of Diagnostic Products Corporation (the “Company”) in connection with the Annual Meeting of Shareholders to be held at the Company’s executive offices located at 5700 West 96th Street, Los Angeles, California, on May 4, 2004, at 2:30 p.m. local time, and any adjournments thereof. It is expected that this Proxy Statement and accompanying proxy will first be mailed to shareholders on or about March 29, 2004.

      The expenses for soliciting proxies for the Annual Meeting will be paid by the Company. Proxies may be solicited by means of personal calls upon, or telephonic or electronic communications with, shareholders or their personal representatives by directors, officers and employees of the Company who will not be specially compensated for such services.

 
VOTING PROCEDURES

      Only shareholders of record of the Company’s Common Stock at the close of business on March 12, 2004, the record date fixed by the Board of Directors, are entitled to notice of and to vote at the Meeting. On that date, there were                      shares of Common Stock outstanding and entitled to vote at the Meeting, each of which is entitled to one vote. A majority of the shares entitled to vote, represented in person or by proxy, constitutes a quorum at the Meeting. Abstentions and broker non-votes are counted as present for purposes of determining the existence of a quorum.

      All shares represented by the accompanying proxy, if the proxy is properly executed and returned, will be voted as specified by the shareholder. If no vote is indicated, the proxy will be voted FOR the Board of Directors’ nominees for director and FOR the approval of the amendment to the Bylaws. A shareholder may revoke his proxy at any time before it has been voted by notifying the Company in writing, by submitting a substitute proxy having a later date or by voting in person at the Meeting.

      If, prior to the election of directors, any shareholder has given notice that he intends to cumulate his votes, then, for the election of directors only, each shareholder may cumulate votes for any nominee, if the nominee’s name was placed in nomination prior to the voting. In cumulative voting for directors, each shareholder is entitled to one vote for each voting share held by him multiplied by the number of directors to be elected. Each shareholder may cast all his votes for a single nominee for director or he may distribute them among any two or more nominees as he sees fit. See “Election of Directors.”

PROPOSAL NO. 1 — ELECTION OF DIRECTORS

      The shareholders are being asked to elect seven directors to serve until the next Annual Meeting of Shareholders and until their successors are duly elected and qualified. The proxies will be voted in favor of the Board of Directors’ nominees, all of whom are currently serving as directors, unless otherwise specifically instructed. Although the Board of Directors does not anticipate that any nominee will be unavailable for election, in the event of such occurrence the proxies will be voted for such substitute, if any, as the Board of Directors may designate.  

      The seven nominees receiving the highest number of affirmative votes of the shares entitled to be voted will be elected directors; votes withheld and broker non-votes have no legal effect. If voting for directors is conducted by cumulative voting, the persons named on the enclosed proxy will have discretionary authority to distribute votes among the nominees in such proportions as they may see fit, unless otherwise specifically instructed. In any case, the proxies may be voted for less than the entire number of nominees if any situation arises which, in the opinion of the proxy holders, makes such action necessary or desirable.

Below is a description of each committee of the Board of Directors. The Board of Directors has determined that all members of the Audit, Compensation and Nominating/ Governance Committees are “independent” in accordance with the listing standards of the New York Stock Exchange.

      Audit Committee: The Audit Committee consists of Kenneth A. Merchant, who serves as Chair, Frederick Frank and Maxwell H. Salter. The Board of Directors has determined that each member has sufficient accounting or related financial management expertise to serve on the Committee and that Mr. Merchant meets the qualifications of an “audit committee financial expert” as defined in the SEC’s regulations.

Management has the primary responsibility for the financial statements and the reporting process, including the system of internal controls. The independent auditors are responsible for performing an independent audit of the Company’s consolidated financial statements in accordance with generally accepted auditing standards and for issuing a report thereon. The full responsibilities of the Committee are set forth in the Audit Committee Charter, which is attached as Appendix A to this Proxy Statement.

      The Compensation Committee has direct responsibility with respect to the compensation of the Company’s chief executive officer and oversees the compensation of the Company’s other executive officers. The Committee has the overall responsibility for approving and evaluating the Company’s director and executive compensation plans, policies and programs and has exclusive authority to administer and make stock option grants under the Company’s stock option plans with respect to the Company’s executive officers. The Committee met once in 2003.

      Nominating/ Governance Committee: The members of the Nominating/ Governance Committee are James D. Watson, Chair, and Kenneth A. Merchant. The responsibilities of the Committee are (i) to identify individuals qualified to become directors and to recommend to the Board the director nominees for each annual meeting of shareholders; (ii) to develop and recommend to the Board the corporate governance guidelines applicable to the Company; and (iii) to oversee the evaluation of the Board and management. This Committee was established in December 2003 and held no meetings during 2003.

      Executive Committee: The members of the Executive Committee are Michael Ziering, Chair, Sidney A. Aroesty and Maxwell H. Salter. This Committee has the authority to exercise the powers of the Board in the management of the business and affairs of the Company when the Board is not in session, subject to the limitations of California law, the Company’s Bylaws and any resolution adopted by the full Board. At least one member of the Executive Committee, currently Mr. Salter, must be an independent director. Any action taken by the Executive Committee must be approved by all members of the Committee.

In January 2003, each of Messrs. Frank, Salter and Watson was granted 10,000 options to purchase Common Stock at an exercise price of $38.68 per share. Mr. Merchant was granted 10,000 options at an exercise price of $33.58 per share in March 2003 upon his election to the Board. The exercise price of the options was equal to the market value of the Common Stock on the grant date.

PROPOSAL NO. 2 — APPROVAL OF AMENDMENT TO THE BYLAWS TO INCREASE THE

MAXIMUM NUMBER OF DIRECTORS

      Our Bylaws currently provide that DPC shall have not less than five nor more than seven directors, and that the exact number within this range may be fixed from time to time by the Board of Directors. Any change to the provision of our Bylaws which prescribes the authorized number of directors requires the approval of our shareholders. In reviewing recent corporate governance matters, the Board of Directors concluded that it would be desirable to increase the number of directors authorized to serve on the Board. The Board of Directors has approved and recommends that you approve an amendment to our Bylaws that increases the maximum authorized number of directors from seven to nine.

      The purpose of this amendment to our Bylaws is to enable DPC to take timely advantage of the availability of well-qualified candidates to serve as independent directors of DPC. The Board of Directors believes that this amendment is in the best interests of DPC and its shareholders because it will enable the Company to add talented individuals with a diversity of experience to our Board.

      Accordingly, it is proposed that the first paragraph of Article III, Section 2 of our Bylaws be amended to read as follows:

        Section 2.     Number and Qualification of Directors.
 
        ‘The number of directors of the corporation shall not be less than five (5) nor more than nine (9) until changed by amendment of the articles of incorporation or by a bylaw amending this Section 2 duly adopted by the vote or written consent of holders of a majority of the outstanding shares entitled to vote; provided that a proposal to reduce the authorized number of directors to a number less than five (5) cannot be adopted if the votes cast against its adoption at a meeting, or the shares not consenting in the case of action by written consent, are equal to more than 16 2/3 percent of the outstanding shares entitled to vote. The exact number of directors shall be fixed from time to time, within the limits specified in the articles of incorporation or in this Section 2, by a bylaw or amendment to the bylaws duly adopted by the vote of a majority of the shares entitled to vote represented and voting at a duly held meeting at which a quorum is present (which shares voting affirmatively also constitute a majority of the required quorum), or by the written consent of the holders of a majority of the outstanding shares entitled to vote, or by resolution of the board of directors.”

      In accordance with the current Bylaws, the Board of Directors has fixed the number of directors constituting the full Board of Directors at seven directors. If the amendment of the Bylaws is approved, the Board of Directors will have authority to increase the size of the Board from time to time up to nine directors. Any vacancy created as a result of an increase in the Board may be filled by the Board of Directors and such person would stand for re-election at the next annual meeting of shareholders following his or her appointment.

Required Vote and Board Recommendation

      The affirmative vote of the holders of a majority of the outstanding shares of Common Stock is required to approve the amendment to our Bylaws. Abstentions and broker non-votes will have the same effect as a vote against the proposal.

      The Board of Directors unanimously recommends a vote FOR the approval of the amendment to our Bylaws. Unless otherwise indicated, the proxy holders named in our proxy will vote the shares represented thereby FOR the approval of the amendment to the Bylaws.

CORPORATE GOVERNANCE

      In response to recently adopted listing standards of the New York Stock Exchange, SEC regulations and evolving corporate governance practices, the Company is in the process reviewing its policies and procedures and, where appropriate, adopting new practices, relating to corporate governance matters.

      Committee Charters: A copy of the current Charter for the Audit Committee is attached to this Proxy Statement as Appendix A. The Audit Committee Charter and the Charters for the Compensation Committee and the Nominating/ Governance Committee, which are in development, will be available on the Company’s website at www.dpcweb.com by May 4, 2004.

      Corporate Governance Guidelines, Code of Ethics and Other Corporate Polices: During 2003, the Company adopted the following policies which are available on the Company’s website at www.dpcweb.com:

  •  Code of Business Conduct — This Code sets forth the Company’s values and expectations regarding ethical and lawful conduct by its directors, officers and employees.
 
  •  Code of Ethics for Senior Financial Officers — The purpose of this Code is to deter wrongdoing and to promote honest and ethical conduct and compliance with applicable laws and regulations by the Company’s senior financial officers.

      The Board of Directors is also in the process of developing corporate governance guidelines to assist the Board in the exercise of its responsibilities. These guidelines will be available on the Company’s website by May 4, 2004.

      Shareholder Recommendations for Board Nominees: The Board believes that all nominees for director should possess the highest personal and professional ethics, integrity and values, and be committed to representing the long-term interests of the Company’s shareholders. In addition, non-management directors should be independent of any particular constituency and be committed to representing all shareholders of the Company. When formulating its recommendations on director nominees, the Nominating/ Governance Committee will take into account, among other factors, the foregoing criteria, the size of the board, and the skills and characteristics then needed for the Board.

      Any shareholder of the Company may recommend a Board nominee to the Nominating/ Governance Committee for its consideration by writing to: Chair, Nominating/ Governance Committee, Diagnostic Products Corporation, 5700 West 96th Street, Los Angeles, California 90045. The nominating shareholder must provide the candidate’s name, contact information, biographical data and qualifications and the candidate’s written consent to be named as a nominee in the Company’s proxy statement and to serve and represent all of the Company’s shareholders if elected. The Nominating/ Governance Committee will consider shareholder nominees on the same basis as other candidates.

      Presiding Director: The Company’s independent directors have appointed Frederick Frank to serve as Presiding Director. The Presiding Director’s responsibilities include presiding over periodic executive sessions of the Board of Directors in which management directors and other members of management do not participate, assisting in the preparation of the agenda for each Board meeting, and facilitating the flow of information from management to the Board. Shareholders and other parties interested in communicating directly with the Presiding Director or with the Company’s independent directors may do so in the manner set forth below.

      Shareholder Communications with Directors: Shareholders and other interested parties may communicate directly with the Board or with any individual director of the Company by calling the Company’s Hotline at 800-932-0034 or by writing to the Board or such individual director in care of the Corporate Secretary, Diagnostic Products Corporation, 5700 West 96th Street, Los Angeles, California 90045. The Corporate

Table of Contents

Secretary will forward written communications to the Chair of the Nominating/ Governance Committee in the case of communications addressed to the entire Board or to the individual directors to whom they are addressed.

      To facilitate and encourage communications between the Company’s shareholders and the directors, directors are expected to attend shareholder meetings. Six of the Company’s seven directors were present at the Annual Meeting of Shareholders held in 2003.

      All outstanding stock options have been granted under stock option plans that have been approved by the Company’s shareholders. Options generally vest at the rate of 10% to 25% per year beginning one year after the date of grant and have ten-year terms. No person may be granted more than 400,000 options in any fiscal year, except that new hires may also be granted up to 400,000 options upon commencement of employment. Options are subject to termination before their expiration date in the event of termination of employment and certain corporate events. All outstanding options will become immediately exercisable in the event of a change-in-control. The Compensation Committee has the authority to modify the terms of outstanding options, including the exercise price and vesting schedule. Non-qualified options granted under the 1997 Stock Option Plan may, if so provided in the option agreement, be transferred pursuant to a domestic relations order or to members of the optionee’s immediate family, charitable institutions or certain related trusts or other entities.

REPORT OF THE COMPENSATION COMMITTEE ON EXECUTIVE COMPENSATION

      The compensation policy of the Company is to provide competitive levels of compensation that are influenced by corporate performance, that reward individual achievements, and that enable the Company to attract and retain qualified executives. Compensation consists primarily of annual salary and long-term incentive compensation in the form of stock options. The Company does not base salaries or bonuses on the achievement of objective performance-related criteria. Bonuses are awarded when, in the Compensation Committee’s judgment, the Company or a particular executive had meritorious performance during the year.

      In determining the compensation of Michael Ziering, the Company’s Chief Executive Officer, the Compensation Committee considers the Company’s overall performance and Mr. Ziering’s responsibilities and contribution to such performance. Since the Committee does not apply objective criteria or formulas, its determination may be deemed informal and subjective. In light of the Company’s strong performance under Mr. Ziering’s leadership, the Committee approved a salary increase from $510,000 in 2002 to $530,000 in 2003 and a $40,000 bonus for 2003.

      The compensation of the Company’s other executive officers is principally based on the recommendations of the Chief Executive Officer and reflects his subjective assessment of the nature of each officer’s position, individual performance, contribution to the Company’s overall performance, experience and tenure with the Company. Other factors which the Committee considers include the desirability of maintaining an appropriate scale among the executive officers based on their relative positions, responsibilities and tenure, the Company’s financial performance and the level of Company-wide U.S. employee compensation increases.

      The objective of granting stock options is to provide long-term incentives through the opportunity to participate in the long-term increase in the market value of the Common Stock. Stock options typically have a term of ten years and become exercisable after one year in cumulative installments which have ranged from 10% to 25% per year for executive officers. Stock options are not awarded annually or pursuant to any formula, but rather are awarded in recognition of outstanding performance, based on the Committee’s and management’s subjective evaluations, and as an incentive to attract new executives. When the Committee decides to grant options, it also takes into account the amount of bonuses, if any, paid for the year and the amount and values of options and Common Stock held by the executive. Based on these considerations, the Committee did not award stock options to executive officers in 2003.

      Section 162(m) of the Internal Revenue Code provides that publicly held companies may not deduct compensation that is not “performance-based” paid to any Named Officer in excess of $1,000,000 in any taxable year. Stock options granted prior to May 2001 may not constitute performance-based compensation. The Company believes, however, that compensation realized upon the exercise of stock options granted after May 2001 will qualify as performance-based compensation.

PROCEDURE FOR SUBMITTING SHAREHOLDER PROPOSALS

      Shareholders interested in submitting a proposal for inclusion in the Company’s proxy statement for the annual meeting of shareholders in 2005 may do so by following the procedures prescribed in SEC Rule 14a-8. To be eligible for inclusion, shareholder proposals must be received by the Company no later than November 30, 2004, and must otherwise comply with the requirements of Rule 14a-8.

      The Company’s Bylaws establish an advance notice procedure with regard to nominations of directors by shareholders and any other business which a shareholder may desire to propose at an annual meeting of shareholders. Notice must be received by the Secretary of the Company not less than 60 days nor more than 90 days prior to the first anniversary of the date on which notice of the prior year’s annual meeting was mailed to shareholders — that is, with respect to the 2005 annual meeting, between December 31, 2004 and January 30, 2005.

  •  the performance of the Company’s internal audit function and independent auditors.

      The Audit Committee has the authority to obtain advice and assistance from legal, accounting or other advisors as deemed appropriate to perform its duties and responsibilities. The Company shall provide appropriate funding, as determined by the Audit Committee, for compensation to the independent auditor and to any advisors that the Audit Committee chooses to engage, and for ordinary administrative expenses of the Audit Committee that are necessary or appropriate in carrying out its duties.

The members of the Committee shall be appointed by the Board on the recommendation of the Nominating/ Governance Committee. Committee members may be removed by the Board.

      Each member of the Committee shall be financially literate (as determined by the Board of Directors in its business judgment) and at least one member shall have accounting or related financial management expertise (as determined by the Board of Directors in its business judgment). No director may serve on the Audit Committee if he simultaneously is serving on the audit committees of more than three public companies, including the Company, unless the Board has determined that such simultaneous service would not impair the ability of such member to effectively serve on the Company’s Audit Committee and such determination is disclosed in the Company’s annual proxy statement.

      The Committee as a whole shall meet at least four times per year on a quarterly basis, or more frequently as circumstances dictate.

Limitation of Audit Committee’s Role

      The Audit Committee relies on the expertise and knowledge of management, the internal auditor and the independent auditors in carrying out its oversight responsibilities.
