Method Validation and Quality Management in the Flexible Scope of Accreditation: an Example of Laboratories Testing for Genetically Modified Organisms

Quality assurance is a prerequisite for accurate and reliable results in food and feed testing, ISO/IEC 17025 being recognized worldwide as the base standard. A flexible scope of accreditation enables testing laboratories to react quickly to customer demand and to cope with the large number of new methods, which have to be introduced in the laboratory. Precisely defined procedures for the validation of methods, together with performance and acceptance criteria, are the key points for flexible scope of accreditation. Testing for genetically modified organisms (GMO) is a challenging exercise, especially with more GMOs entering the world market. We describe here the organization and performance of validating quantitative detection methods for GMO testing in the context of the EU legislation. Operational procedures for method validation organized by the Community Reference Laboratory for Genetically Modified Food and Feed (CRL-GMFF), assisted by the European Network of GMO Laboratories (ENGL) are described. A protocol for validating methods within an individual laboratory is proposed and discussed in terms of the requirements of flexible scope of accreditation. The system setup can be an example for other similar fields of analytical work.
