When my blood sample is reused in biobank research, perhaps 5-10 years after I gave it, do I then become a research subject who must be informed about the new research project and give my assent before the sample is used?
The question arises when I read Joanna Forsberg’s article in BMJ on biobank research and the comments it received. She questions assent for each new biobank project in an interview on Nature News Blog. She thinks it is sufficient that the project has taken precautions that guarantee anonymity and is reviewed by an ethical review board.
Contacting people in thousands long after they gave their samples is not only costly, it also means drop out of samples threatening the validity of the results. Joanna thinks we all have an interest in the existence of biobank research even if we do not gain from research on precisely the samples we gave. Today vaccination against cervical cancer can be offered because in a biobank with patient samples from 1969 a connection was found between HPV virus infection and subsequent falling ill. As a reasonable solution Joanna therefore suggests broad consent to the use our samples in future biobank research.
I don’t know if research on my ten-year-old blood sample makes me a research subject today. One thing is obvious: biobank research does not resemble the standard image of medical research where research subjects after consent undergo treatments and regularly are tested.
