LIMS glossary
Short definitions used across this site. If a vendor uses these words loosely, ask them to show the object in the product.
- AAccessioning
- The controlled registration of a sample into the laboratory system — identity, receipt details, and requested work.
- AAliquot
- A portion taken from a parent sample. A modern LIMS keeps lineage so results on the aliquot still point back to origin.
- AAudit trail
- An attributable, time-ordered history of regulated actions and changes. In Aureon, regulated audit events are append-only.
- CCAPA
- Corrective and Preventive Action — the structured response to a problem and the work to reduce recurrence.
- CCDS
- Chromatography Data System — instrument software that generates chromatographic results, often integrated into LIMS.
- CChain of custody
- The recorded sequence of possession and location for a sample, including who transferred it and when.
- CCoA
- Certificate of Analysis — the controlled report of results against specifications, typically used for release or client reporting.
- CCSV
- Computer System Validation — documented evidence that a system is fit for its intended GxP use.
- DDeviation
- A recorded departure from an approved procedure, method, or expected process.
- DDisposition
- The controlled end state of a sample (for example, retained, consumed, or destroyed) recorded as a lifecycle status.
- EE-signature
- An electronic signature bound to a record and a meaning (reviewed, approved, released), with user identity and timestamp.
- EELN
- Electronic Lab Notebook — a system for experimental narrative and design. Related to, but not the same as, a LIMS.
- IIQ / OQ
- Installation Qualification and Operational Qualification — validation activities that show a system is installed and functions as specified.
- IISO/IEC 17025
- The international standard for competence of testing and calibration laboratories, covering methods, records, and impartiality.
- LLES
- Laboratory Execution System — guided, step-wise execution of methods at the bench.
- LLIMS
- Laboratory Information Management System — the system of record for samples, tests, results, and related laboratory operations.
- LLineage
- Parent-child relationships among samples, aliquots, and derived materials.
- OOOS
- Out of Specification — a result that falls outside approved specification limits and typically requires investigation.
- OOOT
- Out of Trend — a result that is within specification but statistically or historically unexpected.
- PPart 11
- 21 CFR Part 11 — FDA requirements for electronic records and electronic signatures. Software can be designed to support it; laboratories validate it.
- RRBAC
- Role-Based Access Control — privileges granted by role rather than ad-hoc personal exceptions.
- SSDMS
- Scientific Data Management System — capture and context for scientific files, often instrument output.
- SSPC
- Statistical Process Control — use of control limits and charts to monitor method or process performance.
- SSpecification
- Approved limits and criteria against which results are compared for disposition or release.
- 221 CFR Part 11
- See Part 11. Designed-to-support language is required; certification claims are not used on this site.
