How can one find out what blood type they have?!

Donate blood to the American Red Cross. They will type you and send you an individualized I.D. card in the mail with your name and blood type on it.

If you do it this way, your question will be answered, you'll save up to 3 lives, and you'll feel good about yourself.

:D

Edit:
BQ: Absolutely free, even the I.D. card.
BQ2: It's the Red Cross - they aren't allowed to make mistakes.

If you donate blood, it's free. They test the blood and later mail you a little card that tells what blood type you are.........You could also just call a doctor's office or hospital, ask them how much they charge to test your blood only to determine what your blood type is.

Go to the doctors, they will 'draw' and or check your blood. Anytime someone 'gives' blood, they usually tell you what your blood type is. The rate for the accuracy is probably almost 99.9% sure! :) Cost? I don't really know, sorry.
