updated: August 12, 2024

The LIMS world uses what could be called a language of its own. For anyone exploring a new Laboratory Information Management System, this glossary of LIMS-related terms may be of assistance in your journey.

#

21 CFR 11
Title 21 CFR Part 11 is part of the FDA’s Code of Federal Regulations on electronic records and electronic signatures (ERES). It establishes strict guidelines on data integrity, validation, audit trails, and paper record equivalency to ensure compliance with technological advancements for industries that adhere to GxP standards.

Here’s a high-level overview of recent changes to 21 CFR 11. For more insights, see these recent updates co-authored by Clarkston Consulting and Bill Gates.

  • Data Integrity: The FDA has placed a renewed focus on data integrity, emphasizing that it must be complete, consistent, and accurate. This includes ensuring that data is attributable, legible, contemporaneous, original, and accurate (ALCOA+ principles). Companies are directed to implement risk-based strategies to manage data integrity risks based on process understanding and technology​ ​.
  • Audit Trails: The FDA is intensifying its focus on requirements for secure, computer-generated, time-stamped audit trails to ensure that any changes to electronic records are recorded accurately and are retrievable for review.
  • User Authentication and Access Controls: The FDA continues enforcing strict user authentication and accountability controls. Systems must be configured to ensure only authorized individuals can access and modify data.
  • Validation of Electronic Systems: The updated guidance also emphasizes the need for rigorous validation of electronic systems to ensure they perform accurately and consistently. Validation involves testing the system to confirm it meets all intended requirements and functions correctly under anticipated use.
  • Enforcement and Compliance: The FDA has clarified its enforcement discretion regarding certain aspects of Part 11, focusing on a risk-based approach. While earlier guidance allowed for some flexibility, the current stance emphasizes stricter adherence to data integrity and audit trail requirements to prevent data breaches and ensure reliable record-keeping​)​.

Stability Analytics
Statistical analysis, charting, and reporting used in routine product-lot stability studies and shelf-life prediction.

Subject Matter Expert
Subject Matter Experts (SMEs) are individuals with specific expertise in a particular area or field.

System Owner
The System Owner is the person with responsibility for a system, including its support, maintenance and data security. In the context of a LIMS, this is sometimes the IT department. The responsibilities of the System Owner may be delegated, for example, to the Process Owner, particularly in smaller organizations.

T

Thick client
In the context of software, thick client LIMS implement their own features locally and require a full installation on the local computer. While they may connect to a server, thick clients are mostly functional even when disconnected. LIMS software written in Java Swing, C++, and .NET having a local installation may be thick clients.

Thin client
In the context of software, thin clients LIMS are primarily designed to communicate with a server and have few features that fully function when disconnected; they require a small installation on the local computer. LIMS software written in Java Swing, C++, and .NET having a local installation may be thin clients.

Transformer Models
A powerful neural network model capable of understanding relationships in a data series, including distant data elements. The model is widely used in natural language processing tasks, including generating text and translating text and spoken language, and is considered a significant driver of advances in AI.

U

Upstream
A process that occurred earlier in production; e.g., for a finished product, laboratory testing would be upstream from packaging or transportation.

V

Validation
Validation is the activity of establishing documented evidence through execution that a delivered LIMS system successfully fulfills the business’s user requirements, and does so within the intended operating environment. A Performance Qualification is an example of a validation activity

Verification
Verification is the activity of establishing documented evidence through observation and inspection that a LIMS system was designed, developed, and implemented according to original specifications, policies, and procedures. A code review is an example of a verification activity.

Virtual Reality (VR)
Virtual Reality (VR) is the term used to describe a three-dimensional, computer-generated environment that can be explored and interacted with, typically using goggles known as ‘VR headsets’ which fully immerse you in a realistic virtual environment.

VPN
A virtual private network (VPN) extends a private network across a public network, and enables users to send and receive data across shared or public networks as if they were directly connected to a private network.

W

Web portal
See Portal.

Web service
A service offered by one electronic device to another electronic device, communicating with each other via the World Wide Web. Web services are one of the primary methods by which LIMS systems are interfaced to other systems within the business.

Workflow
A sequence of tasks, steps, processes or other activities designed to perform a function.

X

XML
Extensible Markup Language (XML) is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable.

XSS
See Cross-site scripting.

Z

Zero footprint
In the context of software, zero footprint LIMS does not require any installation on the local computer since all functionality is delivered from the server. LIMS software that uses only a web browser is zero footprint.
