Biobanks (i.e. the organised collections consisting of biological samples and associated data, have gained great significance for research and personalised medicine) are increasingly recognised as a crucial infrastructure for research. However, at the same time the widely varied practices in biobanking regarding for example collection, storage and consent procedures may also pose a barrier to cross-border research and collaboration by limiting access to samples and data. In this context the limited sharing and linkage of samples is a key barrier for research, such as pharmacogenetics. Wide variation is observed in the implementation of relevant existing regulation, which may add further burden to harnessing the public health benefit of these collections. It has been suggested that there is a strong need for a harmonised approach on biobanking practices and improved networking of existing and new collections. The Report shows information on the extent of biobanking in Europe, collected through a survey of existing European biobanks regarding both technical aspects (e.g. storage conditions) and aspects of governance and ethics (e.g. sample and data sharing, consent procedures, collaborations etc.). In total, 126 biobanks from 23 countries in Europe were surveyed.
