Analyysialue

Analyysialue is a Finnish term meaning "analysis area." It denotes a designated space or stage where analysis is performed, either physically (in a laboratory) or conceptually (in a workflow). In laboratory practice, analyysialue refers to the part of the workflow where samples are analyzed, as distinct from pre-analytical and post-analytical areas. The purpose is to ensure accuracy, traceability, and contamination control, and to support proper workflow sequencing and contamination control. A typical analyysialue includes instruments for measurement, calibration standards, sample handling tools, and documentation systems for recording results. Access is often restricted to trained personnel, and procedures cover handling, cleaning, and waste management. In data analysis or bioinformatics contexts, analyysialue can describe the stage where data are processed, models run, and results interpreted, with emphasis on reproducibility and data provenance.

The term is common in Finnish laboratory and quality management terminology and is aligned with broader concepts of workflow zoning, good laboratory practice, and ISO 15189 standards. While its exact scope may vary by institution or field, the core idea is to separate analytic work from other steps to minimize errors and maintain audit trails. Etymologically, analyysi means analysis and -alue means area, thus "analysis area."
