Abstract
Research biobanks can offer great benefits for science and healthcare. However, many ethical challenges arise from their use. These challenges have different perspectives in Muslim countries when research biobanks are created. We propose principles for good practice related to the research biobanks in Islamic countries, focusing on issues related to confidentiality, informed consent, children's participation, and others. These issues were explored according to Islamic fatwas and Usul Al Fiqh, and we provide principles for good practice for policy makers involved in the creation of research biobanks, researchers, and anyone who has to deal with stored tissue specimens taken from Muslims. The actual implementation of the principles will vary according to different jurisdictions.
