|
|
No antigens and A and B antibodies
|
|
|
A and B antigens and no antibodies
|
Detailed explanation-1: -blood group O – has no antigens, but both anti-A and anti-B antibodies in the plasma. blood group AB – has both A and B antigens, but no antibodies.
Detailed explanation-2: -But if you have type O blood, your red blood cells have no A or B markers. So: Your body will have both A and B antibodies and will therefore feel the need to defend itself against A, B, and AB blood. A person with O blood can only get a transfusion with O blood.
Detailed explanation-3: -ABO antigens are added to N-linked oligosaccharide chains on the VWF subunit. Thus patients with the type O blood group genotype lack the functional glycosyltransferase that adds N-acetylgalactosamine and D-galactose to the H antigen on VWF in blood group A and B subjects, respectively.
