The primary function of source documents in a clinical trial is to serve as the official record of study procedures. These documents include patient medical records, laboratory reports, and other original records that capture the details of the data generated during the trial. They provide the foundational evidence of what occurred during the study, including participant enrollment, treatment administration, and any adverse events.

Source documents are critical for establishing the integrity of the data collected and ensuring that it is verifiable and traceable throughout the audit and regulatory processes. They support the findings reported in clinical study reports and are essential during inspections by regulatory authorities.
