You should find out, that's important.

It's not really that important in the US at least. I mean not emergently. No one will trust your document and will always do a formal type and crossmatch before providing blood, unless it's emergency release blood and they are giving you O+ (if male) and O- (if childbearing age female or younger).
If a family member comes in and will need a donation, most places are not setup to do an emergent directed donation of blood. It takes time to process the blood for HIV/HepC/CMV, etc... Last I heard was about two weeks from donation to use of a unit of blood but it's probably a bit quicker now.
If you were considering for organ or marrow donation it could help as a quick screen I guess.
Sylvain, was there something else you were getting at that I missed?
Well, I saw the Zombie Ammo at Bradis last week; wonder if they've got the silver bullet Vampire Killer ammo back in stock?Damn vampires trolling INGO again. Now I have to break out the wooden arrows again.
This highly authoritative sites (LOL!) says otherwise....How To Kill A VampireSilver bullets are for werewolves. If they made vampire bullets, they'd have to have wood or garlic essence in them. You got your monsters mixed up.
