How old do you have to be to donate plasma?

This will depend on what type of plasma donation you want to participate in and what state you live in. Every state has different regulations so you should check with your local laws or ask a local plasmapheresis facility.

If you have a disease diagnosis and want to participate in a disease research plasma donation such as those listed at idonateplasma.com, than 17 years old is the minimum with parental consent.
