This paper analyses the information disclosures in two biobank consent documents used by biobanks operating under the General Data Protection Regulation (GDPR). The aim of the analysis is to investigate how these documents inform potential sample donors about possible future uses of biobank data. The findings suggest that the consent documents provide potentially misleading information regarding the range of possible future uses of biobank data. Based on these information disclosures, potential sample donors may reasonably believe that the data can only (...) be used for a narrowly defined range of research purposes. However, the range of lawful uses of the data is much broader and less clearly defined. Consent provided based on misleading information is not morally transformative, even if it were legally valid. To facilitate morally transformative biobank consent, this paper provides two recommendations for information disclosure to potential sample donors regarding future uses of biobank data: first, potential sample donors should be informed about the legal scope of consent; and second, they should be informed about the full range of lawful uses of biobank data.
