The blood type notation A Rh- indicates which antigens and antibodies are present in the blood. A indicates there are A antigens. Rh+ indicates there are Rh antigens. B antibodies. If there are A and Rh antigens but no B antigens, the antibodies in the blood plasma are B antibodies.
Blood types are defined by specific antigens and antibodies present in the blood. Type A has A antigens on red blood cells and anti-B antibodies; Type B has B antigens and anti-A antibodies; Type AB has both A and B antigens with no antibodies; and Type O has no A or B antigens but has both anti-A and anti-B antibodies. This immunological distinction is crucial for safe blood transfusions and organ transplants.
Type B blood has B antigens on the surface of its red blood cells. In addition to these B antigens, type B blood also contains A antibodies in the plasma, which can react against A antigens found in type A blood. This combination of antigens and antibodies is crucial for blood transfusions and compatibility.
Since that person has anti-B antibodies, then A antigens are present in her red blood cells. Since that person doesnt have anti-A antibodies, then there are no B antigens present, which means the person has A type blood.
B+ here is a guide for you: type A - A antigens B antibodies; type B - B antigens A antibodies; Type AB - A&B antigens and no antibodies; type O - no antigens and A&B antibodies. for the rh you just have to add if it is + or -.
Type B antibodies react to type B antigens by begining to clump together, and the clumps may block blood vessels.
Antigens, by definition, cause the body to produce antibodies which act against them. You inherit certain antigens which are on your red blood cells. Sometimes these antigens are absent from your RBC. If you are type B, you have B antigens. Type A has A antigens, AB has AB antigens and type O has no antigens. If you are type AB, you can receive AB blood from some one else.
Type A blood will produce antibodies against B antigens.
Individuals with blood type A positive have antibodies against blood type B antigens. This means their immune system reacts against blood from individuals with blood type B if they were to receive a transfusion containing type B blood.
Blood types that produce anti-B antibodies include type A and type O. Individuals with type A blood have A antigens and produce anti-B antibodies, while those with type O blood lack A and B antigens and produce both anti-A and anti-B antibodies. Therefore, only blood types A and O can produce the antibodies against type B antigens.
Type A blood has A antigens on red blood cells, while type B blood has B antigens. Type A individuals have anti-B antibodies, and type B individuals have anti-A antibodies. Type AB individuals have both A and B antigens, while type O individuals have neither A nor B antigens.
It is the antigens that determine ones blood group.
