Role of Quality Assurance Department in the Handling of OOS Test Results
An interpretation of the “FDA-Guidance for Industry: Investigating Out of Specification (OOS) Test Results” is presented and an FDA compliant procedure for investigating OOS results is proposed. Possible tasks for Quality Assurance are highlighted. In the author’s view an OOS investigation is divided into the three steps identification, investigation and assessment of an OOS. Quality Assurance will support the handling of OOS results in Quality Control laboratories by performing the typical QA tasks e. g. change control, investigation of deviations, SOP tracking and training. At the same time Quality Assurance will gain an overview over the OOS occurrences in QC laboratories. Furthermore QA may perform an OOS trending and will eventually implement corrective and preventive actions to avoid OOS results.
