The Importance of CAG 003 to the Successful Certification of Sterile Compounding Environments

Home Study Webinar

$20 Activity Fee – available through February 28, 2026.

With the long-anticipated changes to USP General Chapter <797>, one unexpected change was the removal of the reference to CETA Application Guide (CAG) 003. This document, published by the Controlled Environment Testing Association (CETA), is a compilation of all the testing required to certify sterile compounding primary and secondary engineering controls. Without it, certification is done at the discretion of the certification provider and could lack critical tests. Additionally, CAG 003 provides detailed requirements for certification documentation and reporting. This home study webinar explores why CAG 003 should be used to guide the certification process and reviews the important components of a certification report.

This home study webinar is a recording of the live activity that was held on March 21, 2023.
