What is 21 CFR Part 11?

21 CFR Part 11 is a set of guidelines issued by the U.S. Food and Drug Administration (FDA) to ensure that electronic records and signatures in regulated industries are as valid, reliable, and secure as their paper counterparts.

The regulations cover various aspects including authentication, audit trails, security controls, and record management, ensuring that electronic data is tamper-evident and can be legally accepted.

Key Requirements for Compliance

To comply with 21 CFR Part 11, organizations must implement a robust Electronic Laboratory Notebook (ELN) or Laboratory Information Management System (LIMS) that supports electronic signatures. This includes ensuring the system is validated to meet regulatory standards.

The system must also provide mechanisms for user authentication, such as unique identifiers and passwords, and maintain an audit trail of all changes made to records.
