ab blood type has what antigens?
437401
Blood group AB individuals have both A and B antigens on the surface of their RBCs, and their blood plasma does not contain any antibodies against either A or B antigen.

ABO incompatibility can occur only if a woman with type O blood has a baby whose blood is type A, type B, or type AB. If a baby is type O there won't be a problem with a negative immune response because type O blood cells don't have immune-response triggering antigens.

ABO Blood Type Just like eye or hair color, our blood type is inherited from our parents. Each biological parent donates one of two ABO genes to their child. The A and B genes are dominant and the O gene is recessive. For example, if an O gene is paired with an A gene, the blood type will be A.

The genotype must be AB. Someone with blood type O has neither the A nor the B allele. The genotype must be OO.

The AB blood group is the result of the intermingling between Caucasian (commonly group A) and Mongolian (commonly group B) people. For these reasons, the AB blood group is found in low percentages throughout the European population, but appears more commonly within the sub-continental Indian population.

For transfusion purposes, they are the same. ... Both subtypes react strongly with the Anti-A reagent used to type patients and is generally not cared about during routine transfusions. You'll still get AB blood regardless of your subtype. So the short answer, is basically they are the same thing.

AB- is only found in less than 1% of the population, making it the most rare and highly in-demand blood type. AB is the most desirable blood type for platelet and plasma donations.

If you have no A or B antigens then you are type O blood. All of this matters because of those antibodies your immune system creates. Someone with type A blood will have antibodies for type B, and someone with type B will have antibodies for type A. Type O has antibodies for both A and B.

Group B: The surface of the red blood cells contains B antigen, and the plasma has anti-A antibody. Anti-A antibody would attack blood cells that contain A antigen.

The ABO system The most important blood group system is ABO, in which your blood is classified as A, B, O or AB. This is determined by two antigens on the red blood cells: A — red blood cells have only the A antigen.

Blood group O (or blood group zero in some countries) individuals do not have either A or B antigens on the surface of their RBCs, and their blood serum contains IgM anti-A and anti-B antibodies.
162489
Blood group B has B antigens with anti-A antibodies in the plasma. Blood group A has A antigens on the red blood cells with anti-B antibodies in the plasma. This combination of antigens and antibodies determine which blood type you can be safely given for medical purposes.

AB is the universal blood type for plasma donations, so we ask donors with the blood type of AB+ or AB- to donate plasma if they are eligible, to make the maximum impact for our patients. We gladly accept whole blood donations from eligible donors with any blood type.

The ABO grouping system refers to the genetically-determined individual differences in the presence of two antigens (A and B), which stimulate the production of different antibodies. Type-O blood has both the antibodies produced in type-A and type-B, whereas type-AB has neither.

Plasma transfusions are matched to avoid A and B antibodies in the transfused plasma that will attack the recipient's red blood cells. People with type AB blood are universal plasma donors. Their plasma does not contain A or B antibodies and can be transfused safely to all blood types.

Human blood is grouped into four types: A, B, AB, and O. Each letter refers to a kind of antigen, or protein, on the surface of red blood cells. For example, the surface of red blood cells in Type A blood has antigens known as A-antigens.
