We and our wholly-owned subsidiaries Osborn Group, Inc., Intellisys, Inc., Lab One Canada Inc., Systematic Business Services, Inc., ExamOne World Wide, Inc., and Central Plains Laboratories, L.L.C., are hereinafter collectively referred to as LabOne. Our risk assessment services comprise underwriting and claims support services including teleunderwriting, specimen collection and paramedical examinations, laboratory testing, telephone inspections, motor vehicle reports, claims investigation services and medical information retrieval to the insurance industry. The laboratory tests that we perform and data we gather are specifically designed to assist an insurance company in objectively evaluating the mortality and morbidity risks posed by policy applicants. The majority of the testing is performed on specimens of individual life insurance policy applicants, but also includes specimens of individuals applying for individual and group medical and disability policies. Our clinical services include laboratory testing services for the healthcare industry as an aid in the diagnosis and treatment of patients. We operate a highly automated and centralized laboratory, which we believe has significant economic advantages over other laboratory competitors. We market our clinical testing services to managed care companies, insurance companies, self-insured groups and physicians. Our clinical services also include substance abuse testing services provided to employers who adhere to drug screening guidelines. We are certified by the Substance Abuse and Mental Health Services Administration to perform substance abuse testing services for federally regulated employers and we currently market these services throughout the country to both regulated and nonregulated employers. Our rapid turnaround times and multiple testing options help clients reduce downtime for affected employees and meet mandated drug screening guidelines. On August 31, 2001, we purchased all of the outstanding capital stock of Osborn Group, Inc., ("Osborn") a leading provider of laboratory testing and other risk assessment services to the life insurance industry. Intellisys, Inc., Applied BioConcepts Inc. and Osborn Laboratories (Canada) Inc., wholly-owned subsidiaries of Osborn, were included in the purchase. As a result of the transaction, we were able to consolidate Osborn's testing and other operations to our Lenexa, Kansas facility. To fund the acquisition and related expenses of the transaction, Welsh, Carson, Anderson & Stowe, IX, L.P. and related purchasers ("WCAS") invested a total of $50 million, consisting of $35 million in convertible preferred stock and $15 million in subordinated debt, in LabOne pursuant to a Securities Purchase Agreement dated August 31, 2001. The subordinated debt was prepaid on December 31, 2002. Funding for the prepayment was obtained from our existing line of credit. Our principal executive offices are located at 10101 Renner Blvd., Lenexa, Kansas 66219 and our telephone number is (913) 888-1770. Our corporate website is www.labone.com. The information on our website does not constitute part of this prospectus. 3 RISK FACTORS Investing in shares of our common stock involves a risk of loss. Certain risk factors are set forth in Exhibit 99 to our Annual Report on Form 10-K for the fiscal year ended December 31, 2002, which is incorporated herein by reference. See "WHERE YOU CAN FIND ADDITIONAL INFORMATION" above. You should carefully consider the risk factors set forth in Exhibit 99 together with all of the other information included in this prospectus and any prospectus supplement and the other information that we have incorporated by reference before investing in our common stock. SELLING STOCKHOLDERS On August 31, 2001, we purchased all of the outstanding capital stock of Osborn. To fund the acquisition and related expenses of the transaction, WCAS invested a total of $50 million in convertible preferred stock and subordinated debt in LabOne pursuant to a Securities Purchase Agreement dated August 31, 2001. In connection with this acquisition financing, we issued warrants to WCAS exercisable at $.01 per share for 350,000 shares of our common stock. We are registering some of the shares of common stock underlying these warrants pursuant to this registration statement. We are a party to several agreements with WCAS relating to its investment in LabOne, including the Securities Purchase Agreement, a warrant agreement and a registration rights agreement. Welsh, Carson, Anderson & Stowe IX, L.P. and certain other stockholders of LabOne are parties to a voting agreement relating to the stock of LabOne. The agreements, and the terms of the Series B-1 Convertible Preferred Stock issued to WCAS in the investment transaction, include provisions relating to the composition of the Board of Directors of LabOne, rights of first refusal as to certain future equity and debt offerings by LabOne and the right of WCAS to veto certain actions or transactions by LabOne. The Series B-1 Convertible Preferred Stock issued to WCAS provides for a cumulative dividend payable in kind, a liquidation preference, conversion rights, anti-dilution provisions, redemption rights, put/call rights, voting rights, rights in the election of directors and certain veto rights. The following table sets forth: o The names of the selling stockholders; o The number and percent of our common stock that the selling stockholders owned prior to this offering (based on holdings that were convertible into or exercisable for common stock); o The number of shares of our common stock that may be offered for the account of the selling stockholders pursuant to this prospectus; and o The number and percent of our common stock to be held by the selling stockholders after the offering (based on holdings that were convertible into or exercisable for common stock and assuming all shares covered by this registration statement are sold by the selling stockholders). This information is based on information provided by the selling stockholders and assumes the sale of all of the shares offered by the selling stockholders. We are unable to determine the exact number of shares that will actually be sold. The applicable percentages of ownership are based on an aggregate of 11,328,219 shares of common stock issued and outstanding as of April 30, 2003. 4 Shares Owned Prior Shares Shares Owned To This Offering Being After This (1)(2) Offered(3) Offering (2)(4) Selling Stockholder Number Percent Number Percent Welsh, Carson, Anderson & Stowe IX, L.P. 4,956,564 30.16% 273,799 4,682,765 28.99% WCAS Management Corporation 2,490 * 147 2,343 * Patrick J.

We will not receive any of the proceeds from the offering of these shares by the selling stockholders. The timing, manner and size of each sale will be determined by the selling stockholders, and not by us. We have been advised by the selling stockholders that the shares offered by this prospectus may be sold from time to time by or for the account of the selling stockholders pursuant to this prospectus or, in some cases, pursuant to Rule 144 under the Securities Act of 1933. Sales of shares pursuant to this prospectus may be made in the over-the-counter market, on the Nasdaq National Market or otherwise at prices and on terms then prevailing or at prices related to the then current market price (in each case as determined by the selling stockholders). Sales may be made directly or through agents designated from time to time, or through dealers or underwriters to be designated or in negotiated transactions. The shares may be sold in one or more of the following ways: o a block trade in which the seller's broker or dealer will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction; o purchases by a broker or dealer as principal and resale by the broker or dealer for their account pursuant to this prospectus (as supplemented or amended to reflect such transaction to the extent required); o an exchange distribution in accordance with the rules of the Nasdaq National Market; o ordinary brokerage transactions and transactions in which the broker solicits purchasers; o privately negotiated transactions; o through put or call option transactions; o through short sales; or o an underwritten public offering. Some of the selling stockholders may distribute their shares, from time to time, to their limited and/or general partners or members, who may sell their shares pursuant to this prospectus (as supplemented or amended to reflect such transaction to the extent required). Each selling stockholder may also transfer shares owned by him by gift, and upon and such transfer, the donee may sell the donee's shares pursuant to this prospectus (as supplemented or amended to reflect such transaction to the extent required). A selling stockholder may enter into hedging transactions with broker-dealers in connection with the distributions of the shares or otherwise. In such transactions, broker-dealers may engage in short sales of the common stock in the course of hedging the positions they assume with the selling stockholder, including positions assumed in connection with distributions of the shares by such broker-dealers. Some or all of the shares covered by this registration statement may be sold to cover short positions in the open market. A selling stockholder also may enter into option or other transactions with broker-dealers that involve the delivery of the shares to the broker-dealers, who may then resell or otherwise transfer such shares pursuant to this prospectus (as supplemented or amended to reflect such transaction to the extent 6 required). In addition, a selling stockholder may loan or pledge shares to a broker-dealer, which may sell the loaned shares or, upon a default by the selling stockholder of the secured obligation, may sell or otherwise transfer the pledged shares pursuant to this prospectus (as supplemented or amended to reflect such transaction to the extent required). The selling stockholders may sell shares directly to other purchasers, through agents or through broker-dealers. Any selling agents or broker-dealers may receive compensation in the form of underwriting discounts, concessions or commissions from the selling stockholders, from purchasers of shares for whom they act as agents, or from both sources. That compensation may be in excess of customary commissions. The selling stockholders and any broker-dealers that participate in the distribution of the shares may be deemed to be "underwriters" within the meaning of the Securities Act of 1933, as amended, in connection with the sales. Any commissions, and any profit on the resale of shares, received by the selling stockholders and any such broker-dealers may be deemed to be underwriting discounts and commissions. We have been advised by each of the selling stockholders that they have not, as of the date of this prospectus, entered into any arrangement with any agent, broker or dealer for the sale of the shares. We have advised the selling stockholders that the anti-manipulation rules of Regulation M under the Securities Exchange Act of 1934, as amended, may apply to sales of common stock in the market and to the activities of the selling stockholders and their affiliates. In addition, we will make copies of this prospectus available to the selling stockholders and have informed each of them of the need for delivery of copies of this prospectus to purchasers at or prior to the time of any sale of the shares offered hereby. We may suspend the use of this prospectus and any supplements hereto in certain circumstances due to pending corporate developments, public filings with the SEC or similar events. We will pay all costs and expenses incurred by us in connection with the registration of the sale of shares pursuant to this prospectus. We will not be responsible for any commissions, underwriting discounts or similar charges on sales of the shares.

INDEMNIFICATION OF DIRECTORS AND OFFICERS We are incorporated under the laws of the state of Missouri. Under Section 351.355 of the General and Business Corporation Law of Missouri, we may, under specified circumstances, indemnify any of our directors, officers, employees or agents who is or was a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding by reason of the fact that such person is or was a director, officer, employee or agent of the company, against expenses, including attorneys' fees, judgments, fines and amounts paid in settlement, actually and reasonably incurred by such person in connection with such action, suit or proceeding. Section 351.355 provides that the indemnification provided by the section shall not be deemed exclusive of any other rights to which those seeking indemnification may be entitled under the articles of incorporation or by-laws of LabOne or any agreement, vote of shareholders, disinterested directors or otherwise. Under Section 351.355, we may purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the company against any liability asserted against such person and incurred by such person in any such capacity, or arising out of such person's status as such, whether or not we would have the power to indemnify such person against such liability under the provisions of Section 351.355. Article IV of our bylaws provides that each person who is or was a director, officer or employee of the company shall be indemnified by us as of right to the full extent permitted or authorized by the laws of the state of Missouri, as now in effect and as hereafter amended, against any liability, judgment, fine, amount paid in settlement, cost and expense (including attorneys' fees) asserted or threatened against and incurred by such person in his or her capacity as or arising out of his or her status as a director, officer or employee of the company. Article IV of our bylaws also provides that no person shall be liable to the company for any loss, damage, liability or expense suffered by the company on account of any action taken or omitted to be taken by him or her as a director, officer or employee of the company if such person (i) exercised the same degree of care and skill as a prudent man would have exercised under the circumstances in the conduct of his own affairs or (ii) took or omitted to take such action in reliance upon the advice of counsel or upon statements made or information furnished by directors, officers, employees or agents of the company which such person had no reasonable grounds to disbelieve. II-1 We have entered into indemnification agreements with our directors and officers under which we have agreed to indemnify such persons against expenses, judgments and fines incurred in connection with the defense or settlement of actions, suits or proceedings, provided such persons' conduct is not finally adjudged to have been knowingly fraudulent, deliberately dishonest or willful misconduct. An Agreement and Plan of Merger between the former LabOne, Inc. and us provides for certain indemnification of officers and directors as well as former officers and directors of the company, as described under "The Merger Agreement- Indemnification" in the Joint Proxy Statement/Prospectus contained in Amendment No. 4 to the registrant's Registration Statement on Form S-4, registration no. 333-76131, filed with the Commission on July 2, 1999. Article IV of our bylaws authorizes us to purchase and maintain insurance on behalf of any director, officer or employee, trustee or agent of the company against any liability asserted against such person or incurred by such person in any such capacity or status, whether or not we would have power to indemnify such person against such liability. We currently maintain directors' and officers' liability insurance to insure our directors and officers against certain liabilities incurred in their capacities as such. ITEM 16. EXHIBITS The index to exhibits appears immediately following the signature pages to this Registration Statement. ITEM 17. UNDERTAKINGS The undersigned registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement. (iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; provided, however, that paragraphs (i) and (ii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15 II-2 of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement. (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the provisions referred to in Item 15 or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act, and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer, or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered hereunder, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question of whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue. II-3 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Lenexa, State of Kansas, on this 20th day of May, 2003.
