Full Description ADOPTED_FROM:EN 15633-1:2019 This document provides an overall framework covering qualitative and quantitative methods for the determination of food allergens and allergenic ingredients using antibody-based methods in foods. This document specifies general guidelines and performance criteria for antibody-based methods for the detection and quantification of proteins that serve as markers for the presence of allergy provoking foods or food ingredients. Other methods than those described can also detect and identify the proteins. Guidelines, minimum requirements and performance criteria laid down in this document are intended to ensure that reproducible results are obtained by different analysts in private and/or official control laboratories or when conducting onsite food testing. This document is intended to be used in addition to EN 15842. NOTE This document could also be applicable to other sample types where the same principles for method validation and verification would apply.
