Item 1.
  Securities and the Issuer
 
   
 
  This statement on Schedule 13D relates to shares of common stock, no par value per share (the “Common Stock”), of Diagnostic Products Corporation (the “Issuer” or the “Company”), a corporation organized under the laws of the State of California, with its principal executive offices located at 5210 Pacific Concourse Drive, Los Angeles, CA 90045.
 
   
Item 2.
  Identity and Background
 
   
 
  This statement is being filed jointly by Siemens Aktiengesellschaft, a corporation organized under the laws of the Federal Republic of Germany (“Siemens AG”), and Siemens Medical Solutions USA, Inc., a corporation organized under the laws of the State of Delaware (“Siemens Med US”).
 
   
 
  Siemens AG has its principal office at Wittelsbacherplatz 2, D-80333 Munich, Federal Republic of Germany. Siemens AG’s business is based in electronics and electrical engineering with strong market positions in equipment for telecommunications and networking, industrial automation, power generation, medical diagnostics, rail transportation systems, automotive electronics, water technologies and lighting.
 
   
 
  Siemens Med US has its principal office at 51 Valley Stream Parkway, Malvern, Pennsylvania, 19355. Siemens Med US is an indirect, wholly-owned subsidiary of Siemens AG and its principal business is the design, development, manufacture and marketing of medical diagnostic and therapeutic systems and devices and information technology systems for clinical and administrative purposes.
 
   
 
  The directors and officers of Siemens AG and Siemens Med US are named on Schedules I and II, respectively, attached hereto. Schedules I and II set forth the following information with respect to each such person:
         
 
  i.   name;
 
       
 
  ii.   business address (or residence address where indicated);
 
       
 
  iii.   present principal occupation or employment and the name, principal business and address of any corporation or other organization in which such employment is conducted; and
 
       
 
  iv.   citizenship.
     
 
  During the last five years, none of the Reporting Persons nor, to the best of each Reporting Person’s knowledge, any person named in Schedule I or II attached hereto, has been (a) convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (b) a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.
 
   
Item 3.
  Source and amount of Funds and Other Consideration
 
   
 
  Concurrently with entering into the Merger Agreement (as defined below in Item 4), Siemens Med US has entered into Shareholder Agreements (the “Voting Agreements”) with certain holders of the Company’s Common Stock, as described in more detail below. The Voting Agreements were entered into as an inducement to Siemens Med US’s willingness to enter into the Merger Agreement (as defined in Item 4 below), and Siemens Med US did not pay any consideration therefore.

Item 4.
  Purpose of the Transaction
 
   
 
  Siemens Med US, Dresden Acquisition Corporation, a corporation organized under the laws of the State of California and a wholly-owned subsidiary of Siemens Med US (“Merger Sub”), and the Company have entered into an Agreement and Plan of Merger, dated as of April 26, 2006 (the “Merger Agreement”). The Merger Agreement provides, among other things, that as soon as practicable after the satisfaction of the conditions set forth in the Merger Agreement and in accordance with the relevant provisions of the California General Corporation Law (the “CGCL”), Merger Sub will be merged with and into the Company (the “Merger”), and that each outstanding share of the Company’s Common Stock (other than certain shares more fully described in the Merger Agreement) will be converted into the right to receive $58.50 per share of the Company’s Common Stock in cash (the “Merger Consideration”), without interest, following the waiver or satisfaction of conditions set forth in the Merger Agreement, including obtaining the approval of the Company’s shareholders. As a result of the Merger, the separate corporate existence of Merger Sub shall cease and the Company will continue as the surviving corporation (the “Surviving Corporation”) and will become a wholly-owned subsidiary of Siemens Med US. If the transactions contemplated by the Merger Agreement are consummated, the shares of the Company’s Common Stock will be delisted from the New York Stock Exchange and deregistered under Section 12(g)(4) of the Securities Exchange Act of 1934.
 
   
 
  Under the Merger Agreement, unless otherwise determined by Siemens Med US, from and after the effective time of the Merger (the “Effective Time”) the directors and officers as provided in the Merger Agreement shall be the initial directors and officers of the Surviving Corporation. Such persons shall serve as directors or hold office in accordance with the articles of incorporation and bylaws of the Surviving Corporation. Further, under the Merger Agreement, the articles of incorporation and bylaws of Merger Sub, as in existence immediately prior to the Effective Time, shall be the articles of incorporation and bylaws of the Surviving Corporation from and after the Effective Time unless and until amended in accordance with their terms and as provided by applicable law.
 
   
 
  Concurrently with entering into the Merger Agreement, Siemens Med US entered into a Voting Agreement with each of Marilyn Ziering, Michael Ziering and Ira Ziering (each a “Shareholder” and, collectively, the “Shareholders”), each dated as of April 26, 2006, pursuant to which, among other things, each Shareholder has agreed to cause his or her shares of the Company’s Common Stock to be voted (i) in favor of the approval of the Merger Agreement and the Merger and (ii) against any Acquisition Proposal (as defined in the Voting Agreement) other than the Merger. Except as otherwise provided in the Voting Agreements, each Shareholder (i) has agreed not to sell, transfer, pledge, or otherwise dispose of any of his or her shares of the Company’s Common Stock or offer to make such a sale, transfer, pledge or other disposition; (ii) has waived and agreed not to exercise or assert any applicable appraisal rights under Chapter 13 of the CGCL in connection with the Merger; and (iii) has agreed to execute and deliver such other documents and instruments and take such further actions as are necessary in order to ensure that Siemens Med US receives the benefit of his or her respective Voting Agreement.
 
   
 
  Each of the Voting Agreements terminates upon the earliest to occur of (i) the mutual written consent of Siemens Med US and the Shareholder; (ii) the Effective Time; (iii) the termination of the Merger Agreement in accordance with its terms; or (iv) an amendment to the Merger Agreement that reduces or otherwise changes the form of the Merger Consideration to which the Shareholders would have been entitled.
 
   
 
  Pursuant to each of the Voting Agreements, the respective Shareholder appointed Siemens Med US as such Shareholder’s proxy to vote such Shareholder’s shares of the Company’s Common Stock at any meeting of shareholders of the Company or in other circumstances (i) in favor of the approval of the Merger Agreement and the Merger and (ii) against any Acquisition Proposal other than the Merger. Under the terms of each of the Voting Agreements, each respective Shareholder affirmed that his or her proxy is coupled with an interest and (subject to the terms of the Voting Agreement) may under no circumstances be revoked, and agreed not to enter into any agreement or commitment the effect of which would be inconsistent with or violative of the provisions of the Voting Agreement.

Item 5.
  Interest in Securities of the Issuer
 
   
 
  Siemens Med US, pursuant to the Voting Agreements, has acquired the right to vote 5,526,985 shares of the Company’s Common Stock, representing 18.7% of the outstanding shares of the Company’s Common Stock as of April 24, 2006, in favor of the Merger (as described in Item 4) and, for the purposes of Rule 13d-3 promulgated under the Securities Exchange Act of 1934, Siemens AG and Siemens Med US may be deemed to beneficially own 5,526,985 shares of the Company’s Common Stock, representing 18.7% of the outstanding shares of the Company’s Common Stock as of April 24, 2006. Siemens AG, Siemens Med US and any person named in Item 2 disclaim beneficial ownership of such shares of the Company’s Common Stock. Siemens Med US has power to vote or to direct the voting of 5,526,985 shares of the Company’s Common Stock pursuant to the Voting Agreements as described in Item 4. Except as described in this Schedule 13D, to the best knowledge of Siemens AG and Siemens Med US, no person named in Item 2 beneficially owns any shares of the Company’s Common Stock. Except as described in Item 4, during the past 60 days there have been no other transactions in the securities of the Issuer effected by Siemens AG, Siemens Med US or, to the best knowledge of Siemens AG and Siemens Med US, the other persons named in Item 2.
 
   
Item 6.
  Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer
 
   
 
  The Merger Agreement is filed as Exhibit 2.1 of the Issuer’s Current Report on Form 8-K filed with the Securities and Exchange Commission on May 1, 2006 and is incorporated herein by reference. The Voting Agreements are attached as exhibits to this Schedule 13D. The summaries of such agreements contained in this Schedule 13D are qualified in their entirety by reference to such agreements.
 
   
 
  Except as provided in the Merger Agreement and the Voting Agreements or as otherwise described in this Schedule 13D, to the best knowledge of Siemens AG and Siemens Med US, there is no contract, arrangement, understanding or relationship (legal or otherwise) among the persons named in Item 2 and between such persons and any person with respect to any securities of the Issuer, including, but not limited to, any contract, arrangement, understanding or relationship concerning the transfer or voting of such securities, finder’s fees, joint ventures, loan loss, guarantees of profits, division of profits or loss or the giving or withholding of proxies.
