Do I have to tell my family if I decide to do it?
The NHS Organ Donor Register is a national, confidential database holding the details of more than 19 million people who want to donate their organs when they die.
Adding your name to the NHS Organ Donor Register will make your wishes clear. You can join the register online at www.organdonationscotland.org/register-now or by calling the NHS Donor Line on 0300 123 23 23.
You should definitely discuss this with your family and medical staff so they are aware of your wishes.
There is no age limit to becoming a donor. A person's physical condition, not age, is the deciding factor. Most people waiting for a donated organ need to have a kidney, heart, lung or liver transplant.
One donor can help several people because a single donor can donate a number of organs and tissues. All donors have the choice of which organs and tissues they wish to donate.
