RESUMEN
Biological samples such as tissues, blood and other body fluids, plants or seeds, prokaryotic and eukaryotic cells or isolated biomolecules as well as associated data are the essential raw material for research and development in medicine, biotechnology and agriculture. The collection, processing, preservation, and storage of these resources, in addition to provision of access, are key activities of biobanks or biological resource centres. Biobanks have to ensure proper quality of samples and data, ethical and legal compliance as well as transparent and efficient access procedures. In this context the review places special emphasis on pre-analytical procedures and international standards, which are essential to improving analytical data reliability and reproducibility, as well as on the increasing importance of data management. These requirements of biobanks are demonstrated using the example of pathogen-containing and microbiome biobanks, and refer to needs in cancer research and development.

In May 2017, the European In Vitro Diagnostic Regulation (IVDR) entered into force and will apply to in vitro diagnostics from May 26th, 2022. This will have a major impact on the in vitro diagnostics (IVD) industry as all devices falling under the scope of the IVDR will require new or re-certification. It will also affect health institutions developing and using in-house devices. The IVDR also has implications with respect to product performance validation and verification including the pre-analytics of biological samples used by IVD developers and diagnostic service providers. In parallel to the IVDR, a series of standards on pre-analytical sample processing has been published by the International Organization for Standardization (ISO) and the European Committee for Standardization (CEN). These standards describe pre-analytical requirements for various types of analyses in various types of biospecimens. They are of relevance for IVD product developers in the context of (re)certification under the IVDR and to some extent also to devices manufactured and used only within health institutions. This review highlights the background and the rational for the pre-analytical standards. It describes the procedure that leads to these standards, the major implications of the standards and the requirements on pre-analytical workflows. In addition, it discusses the relationship between the standards and the IVDR.
