I think the most common blood type is O because it seems many people's blood type is O. My blood type is B by the way.
I love China

like the post above its 0+ but if your including the other blood groups then there are rarer blood types still.
well almost all people no the ABO blood type and the + - which is the rh blood group.
but there are other rarer blood group system out there like kell, duffy, kidd, Xg and many many more.
