More individuals can become tissue donors than organ donors.
Organ donors must be declared brain dead in a hospital, and their organs maintained by artificial support until removed. Even when an autopsy is required, as it is for homicides and some accident victims, tissue donation is a realistic possibility. Even people over age 80 or those affected by disease may be able to donate tissue. If you wish to be a tissue donor, the important thing is to sign a donor card and to make sure that your family understands your wishes. An allograft is tissue that has been taken from one person and used in another.
