Ethical issues are commonly present in many aspects of Biobanking. The fact that Biobanks deal with human samples, invading an individual autonomy or limiting self-control, provokes a number of ethical issues. Who is actually competent to give informed consent and donate a sample? When individuals donate part of their body to a biobank, how is that human sample processed? Who is the owner of the sample? Who should decide how it should be used? Who has the right to know individual results of research? These and many more ethical dilemmas exist in the ethical framework of biobanks. With the recent rapid developments in biobanking, all of these issues are magnified with plenty of further new questions continuously arising. Ethical framework has been the most controversial issue in the domain of biobanking. Thus, it is not surprising that there is a substantial literature focusing on ethical dilemmas in biobanking, such as informed consent, privacy, protection, and returning of results to participants. For many years, researchers at CRB have provided constructive advice on how to deal with ethical aspects of research using human tissue material and personal data.
