blood type A
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".
Type B antibodies react to type B antigens by begining to clump together, and the clumps may block blood vessels.
Blood group AB
true
anti-B
A - blood type
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.
both anti a and anti b antibodies, that's why they are the universal donar Group O type there is a presence of antibody A and antibody B and the red cells has no antigen A and antigen B and in terms of blood component (Packed red cells) it can be considered as safe "O"(universal ) because of the absence of ag. A and ag B.
Individuals with type A blood produce anti-B antibodies and individuals with type B produce anti A. There are many sub groups of blood antibodies such as D (Rh) but we usually only refer to the ABO systems.
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 -.
As Blood type O contains Anti-A-Antibodies and Anti-B-Antibodies (not Antigens) Anti-A-Serum contains Anti-A-Antibodies (which reacts with A antigen not antibody) Anti-B-Serum contains Anti-B-Antibodies (which reacts with B antigen not antibody) so antibody in antiserum will not find any antigen in blood-group O to react with so no Clumping
