NuGO Guideline 18

Use and exchange of data and samples

Use of biological materials and data in further research projects

Secondary use of stored biological material, in the context of these guidelines meaning the study aim differing from the original one, should always be subject to ethical approval. Where data and samples are not unlinked anonymized, consent should be renewed if possible with reasonable effort (see Guideline 1, see Guideline 5). All information and communication tools such as advertisement, mailing, inquiry to registries etc. should be used to trace the research volunteer concerned. However, if expenses are disproportionately or if the donor is dead the effort for renewal of consent would be unreasonable. In those cases, the biological material should only be used after an independent evaluation (see Guideline 5).
