16.	SEGMENT AND RELATED INFORMATION

The Company’s business units have been aggregated into two reportable segments: (i) diagnostics and (ii) other. The diagnostics segment primarily provides testing and collaborative development of testing that is designed to assess an individual’s risk for developing disease later in life, identify a patient’s likelihood of responding to drug therapy and guide a patient’s dosing to ensure optimal treatment, or assess a patient’s risk of disease progression and disease recurrence. The other segment provides testing products and services to the pharmaceutical, biotechnology and medical research industries, research and development, and clinical services for patients, and includes corporate services such as finance, human resources, legal and information technology. Prior periods presented have been recast to conform to the current presentation.

The accounting policies of the segments are the same as those described in the summary of significant accounting policies (Note 1). The Company evaluates segment performance based on income (loss) before interest income and other income and expense.
