Laboratory and LIMS terminology explained


AR - Analysis Request #
A Bika LIMS term for the collection of concurrently requested analyses for a sample, or order for analysis services. ARs have unique IDs and transaction logs
FLOSS - Free/Libre/Open-Source Software #
FLOSS refers to both Free Software and Open Source Software. FLOSS is liberally licensed to grant the right of users to use, study, change, and improve its design through the availability of its source code. This approach has gained both momentum and acceptance as the potential benefits have been increasingly recognized by both individuals and corporations. In the context of free and open-source software, free refers to the freedom to copy and re-use the software, rather than to the price of the software. Wikipedia
PT - Proficiency Testing #
The aim of Proficiency Testing - also known as Inter-Laboratory Comparison Programmes, ILCP, or Proficiency Schemes - is to provide laboratories with objective assessments of the accuracy and reliability of their test results. Proficiency Testing also provides the opportunity for laboratories to benchmark their performance within a pooled industry group, nationally or internationally.


ISO/IEC 17025 #
ISO/IEC 17025 is the main standard used by testing and calibration laboratories. Originally known as ISO/IEC Guide 25, ISO/IEC 17025 was initially issued by the International Organization for Standardization (ISO) in 1999. There are many commonalities with the ISO 9000 standard, but ISO/IEC 17025 adds in the concept of competence. It applies directly to organisations that produce testing and calibration results. The 2005 edition introduced greater emphasis on the responsibilities of senior management, and explicit requirements for continual improvement of the management system itself, and particularly, communication with the customer. The ISO/IEC 17025 standard itself comprises five elements that are Scope, Normative References, Terms and Definitions, Management Requirements and Technical Requirements. The two main sections are Management Requirements and Technical Requirements. Management requirements are primarily related to the operation and effectiveness of the quality management system within the laboratory. Technical requirements includes factors which determines the correctness and reliability of the tests and calibrations performed in laboratory. Laboratories use ISO 17025 to implement a quality system aimed at improving their ability to consistently produce valid results. It is also the basis for accreditation from an Accreditation Body. Since the standard is about competence, accreditation is simply formal recognition of a demonstration of that competence. A prerequisite for a laboratory to become accredited is to have a documented quality management system. The usual contents of the quality manual follow the outline of the ISO/IEC 17025 standard.
