Do you know your blood type? Care to share with us?

I've had many blood transactions and I still don't know my blood type. I hope to find out soon, I haven't had blood drawn from me in a while now, so I'm pretty curious.

I took the effort to look at all the Blood Type groups on the American Red Cross website, and I found this:


Group A – has only the A antigen on red cells (and B antibody in the plasma)
Group B – has only the B antigen on red cells (and A antibody in the plasma)
Group AB – has both A and B antigens on red cells (but neither A nor B antibody in the plasma)
Group O – has neither A nor B antigens on red cells (but both A and B antibody are in the plasma)

I am O

I am A-
