There is no age limit for organ donation. The Donor Network has successfully procured organs from donors as young as a few days to adults in their 90s. A patient's medical history is more important than the age of the donor. If a patient has a normal functioning organ and is in good health, then organ donation is certainly an option.
Newborns as well as senior citizens have been organ donors. If you are under age 18, you must have a parent's or guardian's consent. If you are 18 years or older, you can show you want to be an organ and tissue donor by signing a donor card.
