Your blood type is determined by what type of antigen you have in your body. Each person has different antigen's or lack there of in the blood. A blood test is used to determine what these are.
If the blood type is AB then the agglutinin would be O because agglutinin is what we do not have. Since the person has AB type blood, he/she does not have O type blood.
Blood Type 'O': Red Blood cells have neither A-antigen, nor B-antigen but generates both Anti-A and Anti-B antibodies - Blood Type 'A': Red blood cells have the A-antigen which generates the Anti-B antibodies Blood Type 'B': Red blood cells have the B-antigen and generate Anti-A antibodies The lack of antigen explains why Type "O" can safely donate to Type "A" and Type "B". The Anti-A and Anti-B antibodies generated by Type "O" is the reason "O" cannot receive donations from Type "A" or Type "B".
Because the immune system of anyone with type AB blood is used to the presence of both the A and the B antigen on red blood cells. Therefore it will not fight type A blood with the A antigen present. (The immune system never detects the lack of antigens, only their presence). On the other hand, a person with type A blood carries only the A antigen on the surface of their erythrocytes. Their immune system detects and fights the B antigen.
Blood type A have antigen A and anti- body B Blood type B have antigen B and anti- body A Blood type AB have antigens A and B and no anti- body Blood type O do not have antigen but have anti- bodies A and B
there are no antigen in O blood and both A and B antigen in O blood.
blood type A have antigen A and anti body B blood type B have antigen B and anti body A blood type AB have antigens A and B and do not have anti body blood type O do not have antigen but have anti bodies A and B
Blood type D is not one of the four main blood type groups. There is a D antigen that is part of the Rh antigen system, but there is not a blood type group called blood type D.
Blood type has to do with the antigens found on the surface of your red blood cells. Type A has the A antigen, type B has the B antigen, type AB has both, and type O has neither.
Rh is an antigen that your blood either does (+ type) or does not have (- type). These are not compatible with each other as the antigen in a body without is rejected by the body.
Basically, Group A Rh (D) +ve blood type has antigen A and antibody B
Rh antigen, which is also called D antigen, indicates if the blood type is positive or negative. The presence of this antigen indicates the patient is Rh positive, the absence of this antigen reflects a blood type of Rh Negative. For example, if a person is O Positive, the Rh antigen is present.
