and wats the difference between A positive , A negative n bla bla...? mine is AB+
Blood group is determined by several antigens.
A, B and i allele (antigen) system - this is responsible for A, B, AB, O groups
C, D, E antigens - this is responsible for rhesus groups +ve and negative. ccddee geno-type will be Rh negative. All others are Rh +ve.
Kell, Duffy antigens - these are minor blood groups. Expressed as Kell + or Kell negative.
For a successful blood transfusion all the above criteria should match or be compatible. Blood cross match is the term used for this test.
BTW I am O positive, with Kell and Duffy antigens positive (you have to work n a blood bank to know the latter information)
