BUSINESS SEGMENT INFORMATION

BUSINESS SEGMENT INFORMATION

Clinical testing is an essential element in the delivery of healthcare services. Physicians use clinical tests to assist in the detection, diagnosis, evaluation, monitoring and treatment of diseases and other medical conditions. Clinical testing is generally categorized as clinical laboratory testing and anatomic pathology services. Clinical laboratory testing is generally performed on whole blood, serum, plasma and other body fluids, such as urine, and specimens such as microbiology samples. Anatomic pathology services are principally for the detection of cancer and are performed on tissues, such as biopsies, and other samples, such as human cells. Customers of the clinical testing business include patients, physicians, hospitals, employers, governmental institutions and other commercial clinical laboratories. The clinical testing business accounted for greater than 90% of net revenues from continuing operations in 2012 and 2011.

All other operating segments include the Company's non-clinical testing businesses and consist of its risk assessment services, clinical trials testing, healthcare information technology, and diagnostics products businesses. The Company's risk assessment services business provides underwriting support services to the life insurance industry including electronic data collection, specimen collection and paramedical examinations, laboratory testing, medical record retrieval, case management, motor vehicle reports, telephone inspections, prescription histories and credit checks. The Company's clinical trials testing business provides clinical testing performed in connection with clinical research trials on new drugs, vaccines and certain medical devices. The Company's healthcare information technology business is a developer and integrator of clinical connectivity and data management solutions for healthcare organizations, physicians and clinicians that can help improve patient care and medical practice. The Company's diagnostics products business manufactures and markets products that enable healthcare professionals to make healthcare diagnoses, including products for point-of-care, or near-patient, testing for the professional market. During the second quarter of 2011, the Company acquired Athena and Celera. Athena is included in the Company's clinical laboratory testing business. The majority of Celera's operations are included in the Company's clinical laboratory testing business, with the remainder in other operating segments. A full description of the Company’s acquisitions is contained in Note 4 to the Consolidated Financial Statements in the Company’s 2011 Annual Report on Form 10-K.
