ISO 21571:2005 is an international standard for analyzing foodstuffs to detect genetically modified organisms (GMOs) and their products. It specifically addresses the extraction, purification, and quantification of nucleic acids (DNA) from food matrices. This standard is designed to be part of a broader set of nucleic-acid-based analytical methods, including those for qualitative and quantitative analysis, as specified in ISO 21569 and ISO 21570, respectively.
