The deceased's family is also told what the register says and they're asked if he or she had changed their mind, or if the family has sincerely held objections to donation. Potential donors are encouraged to discuss their decision with their family to ensure their wishes are known to them. An individual may consent to the use of all organs and tissues, or just some (if someone has strong views about particular body parts for instance). The consent is entirely voluntary and may be changed or withdrawn at any time. The register is only for organ donation; it does not cover other uses for organs such as scientific research.
