The role of QAU in GLP: What is the purpose of a phase audit?

SQA 2025 -- The purpose of the phase audit is to monitor each study to provide assurance to test facility management. The phase audit report is sent to both the study director and to test facility management. The Quality Assurance Unit (QAU) is independent, meaning that they cannot participate in the study that they audit, and they cannot report into the study director.
