THIRD QUARTER ANALYSIS

Revenue for the quarter ended September 30, 2004, was $117.8 million compared to $88.1 million in the third quarter 2003. The increase of $29.7 million, or 34%, was due to increases in clinical healthcare revenue of $19.4 million, risk assessment revenue of $6.7 million and clinical SAT revenue of $3.7 million. Risk assessment revenue increased to $64.6 million from $58.0 million in the third quarter 2003 due primarily to increases of $4.3 million in paramedical services and $2.8 million in other insurance services, partially offset by a decrease in insurance laboratory services of $0.5 million. Paramedical services revenue increased due to an increase in the number of paramedical exams performed from new customer accounts and the acquisition of a Canadian paramedical provider. Other insurance services increased primarily due to growth in teleunderwriting services, motor vehicle reports and medical records retrieval. Insurance laboratory revenue decreased due to a 3% decline in the average revenue pe r applicant. During the third quarter 2004, healthcare services revenue increased to $42.2 million from $22.8 million in 2003 due to the acquisition of Alliance Laboratory Services in January 2004 and a 19% increase in organic testing volumes. Alliance Laboratory Services accounted for $14.1 million of the revenue increase, and increased sales to new and existing healthcare customers accounted for $5.3 million of the revenue increase. SAT revenue increased $3.7 million to $11.0 million in the third quarter 2004 from $7.3 million in 2003 due to the addition of Northwest Toxicology and an 11% increase in organic testing volumes.

Cost of sales increased $20.7 million, or 34%, in the third quarter 2004 as compared to the prior year, due primarily to the acquisitions of Alliance Laboratory Services and Northwest Toxicology, and increases in paramedical collections, motor vehicle report fees and payroll expense. Paramedical services increased primarily due to continued growth of the ExamOne paramedical operations and the acquisition of a Canadian paramedical provider. Motor vehicle report fees increased due to sales growth. Payroll increased due to increased specimen volume in the healthcare and substance abuse laboratory testing segment and growth of teleunderwriting. Risk assessment cost of sales, including all of the above mentioned factors, increased to $46.9 million in 2004 from $41.9 million in the third quarter 2003.

Clinical healthcare overhead expenditures increased to $8.2 million as compared to $4.7 million in 2003 due to the acquisition of Alliance Laboratory Services and an increase in payroll expense.

Clinical SAT overhead expenditures increased to $1.5 million as compared to $0.8 million in 2003 due to the acquisition of Northwest Toxicology. Corporate overhead expenses increased to $10.4 million from $8.7 million in the third quart er 2003 primarily due to higher payroll and depreciation, principally related to information technology initiatives and expenses related to compliance with the Sarbanes-Oxley Act of 2002.

Net cash provided by operations was $37.3 million as compared to $19.2 million in the first nine months of 2003.

During June 2004, the Company issued $90 million of 3.50% convertible senior debentures due June 15, 2034 in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933.

The debentures may be converted, under certain circumstances, into a combination of cash and common stock of the Company at an initial rate equivalent to a conversion price of $39.30 per share of common stock, subject to certain adjustments. Holders may convert the debentures if the common stock price exceeds 130% of the conversion price for 20 trading days in the 30 trading day period ending on the last trading day of the preceding fiscal quarter. Upon conversion, the Company will deliver cash equal to the lesser of the aggregate principal amount of debentures to be converted and the conversion obligation, and common stock in respect of the remainder, if any, of th e conversion obligation. The Company may not redeem the debentures prior to June 20, 2009. Holders of the debentures may require the Company to repurchase some or all of the debentures on June 15, 2011, 2014 and 2024 and upon certain specified corporate transactions.

During the third quarter, the Company increased commitments under its revolving credit facility from $150 million to $175 million. The line of credit bears variable interest which, as of October 29, 2004, was 3.8% and requires a commitment fee of 0.5% on the unused portion of the commitment. Based on covenants, $70.3 million of the remaining $174.2 million was available for borrowing as of September 30, 2004.

As of September 30, 2004, the Company had $9.0 million outstanding of industrial revenue bonds issued to finance the construction of the Company's Lenexa facility.

As of September 30, 2004, LabOne had total cash and cash equivalents of $20.6 million as compared to $4.7 million as of December 31, 2003. The Company expects to fund operations from a combination of cash flows from operations and borrowings under the credit facility.

As of September 30, 2004, LabOne's liability subject to variable interest rates was $9.8 million. The associated market risk exposure is not considered to be material. A foreign currency risk exposure exists due to sales in Canada in Canadian dollars and the direct laboratory expenses associated with this revenue being incurred in US dollars. This exposure is not considered to be material.

The Company maintains disclosure controls and procedures that are designed for information required to be disclosed in the Company's reports filed pursuant to the Securities Exchange Act of 1934, as amended, to be recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms. Disclosure controls and procedures also are designed for such information to be accumulated and communicated to the Company's management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system's objectives will be met.

Management of the Company, including the Chief Executive Officer and Chief Financial Officer, conducted an evaluation of the effectiveness of the Company's disclosure controls and procedures as of the end of the period covered by this report. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the Company's disclosure controls and procedures were effective as of the end of the period covered by this report to provide reasonable assurance that the control system's objectives would be met.

There were no changes in the Company's internal controls over financial reporting during the third quarter of fiscal 2004 that materially affected, or that are reasonably likely to materially affect, the Company's internal control over financial reporting.

As previously reported, during the third quarter of 2004, the Company's internal auditors identified a reportable condition in the design and operation of general computer controls related to program changes and access security. The condition is not considered a material weakness. The Company believes it has addressed and remediated the issues concerning program changes. The Company has implemented certain changes in security access, and has plans for completion of remediation during the fourth quarter.

(c) In 2000, the Company's Board of Directors authorized a share repurchase program to purchase up to $10 million of LabOne common stock. The program does not have an expiration date. During 2000, the Company repurchased 841,000 shares of common stock at an average price of $7.07 per share for a total of $5.9 million. The Company has not repurchased any shares of common stock since 2000. Approximately $4.1 million remains available for future treasury stock purchases.

Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned thereunto duly authorized.
