Actually O negative is the universal donor. O negative has no Rh antigens (presence or absence of Rh antigens determines the + or - status of blood) and no A or B antigens, meaning that people with other blood types don't have an immune reaction to the blood. With your DH being O and positive for Rh antigens, he can only give to other blood types that are positive as well. If that blood were to go to someone with negative blood, the anti Rh antibodies in that person's body would cause an immune reaction.
On the flip side, AB+ can get eeeeeverything. Wouldn't that be nice to be a universal receiver, never having to worry if you were in some sort of accident or having surgery and needed blood?
Thanks for the correction. Now I wonder which I was wrong about, did I hear wrong when they said he was a universal donor or when they said he was o+??
