Organ Donation

The agreement of a person (or his or her family) to surgical removal of one or more organs for use in transplant surgery.

Compatible living donors may also be able to give a kidney (see tissue-typing).

People can facilitate use of their organs after death by informing relatives and carrying a donor card.
