The Admin seems to have adjusted non-human blood to human types. I dunno quite how that works out, but theoretically, it should be safe to do transfusions for you, as well. If you ask about your blood type, it'll just have a modifier, 'adj' attached to it. That signifies the Admin's changed your blood.
