# Regulation

## Overview

The Regulation category provides section widgets that help laboratories maintain traceability, approval control, and audit-ready record management directly inside Labii ELN and LIMS. These widgets are designed for workflows where it matters not only what was documented, but also who changed it, who viewed it, and who formally approved it. Together, they support regulated and quality-sensitive environments such as GLP-style documentation, FDA 21 CFR Part 11-oriented electronic records, and internal compliance review processes. Whether you need audit trails, immutable version history, visitor logs, or controlled electronic signoff, this category keeps those controls attached to the same record as the scientific or operational work.
