Panel Discussion/Round Table

Laboratory and Data Quality Management

What laboratory and QA/QC practices are useful to simplify, economize, and speed analyses while ensuring that results are good enough to meet needs?

Laboratory Quality Management is an evolving and advancing field, just as other aspects of analytical chemistry.  For example, ISO 17025 has recently been updated, and new developments in AOAC International and EU guidelines have been implemented.  In statistics, assessments taking into account probability of detection, qualitative analysis, and spurious errors are becoming more prominent.  Greater availability of analytical standards, reference materials and proficiency testing samples is leading to better evaluation of methods and laboratory performance.  In terms of efficiency, options to (re-)validate methods using ongoing QC samples for representative analytes and matrix types can be conducted.  Since the "fit-for-purpose" and "good enough" data quality factors entail elements of subjectivity, all parties (managers, analysts, regulators, clients, QA/QC officers, and accreditors) need to have open communication about setting data quality objectives and QA/QC practices that effectively meet the needs for the results most efficiently.  The goal of this panel session is to reach a reasonable consensus in answer to the question:  "What is enough validation and quality control to demonstrate that method performance is good enough?"
