Segment Reporting [Abstract]

Segment Reporting

SEGMENT REPORTING

We operate primarily through three business segments: diagnostic and information management-based products and services for the companion animal veterinary industry, which we refer to as CAG; water quality products (“Water”); and diagnostic products and services for livestock and poultry health, improve producer efficiency, and to ensure the quality and safety of milk, which we refer to as LPD. Our Other operating segment combines and presents our human medical diagnostic products and services business with our out-licensing arrangements because they do not meet the quantitative or qualitative thresholds for reportable segments. 

Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision-maker (the "CODM"), or decision-making group, in deciding how to allocate resources and in assessing performance. Our CODM is our Chief Executive Officer. Our reportable segments include: CAG, Water, LPD, and Other. Assets are not allocated to segments for internal reporting purposes.

CAG provides products and provide services for veterinarians and the biomedical research community, primarily related to diagnostics and information management. Water provides a range of innovative products used in the detection and quantification of various microbiological parameters in water. LPD provides diagnostic tests and related instrumentation and provides services that are used to manage the health status of livestock and poultry, to improve producer efficiency, and to ensure the quality and safety of milk. OPTI Medical develops, manufactures, and distributes human medical diagnostic products and provides human medical diagnostic services.
