universal recipient is blood type ____. universal donor is type __ blood.
AB, O
Occurs when surface antigens (agglutinogens) are exposed to corresponding antibodies (agglutinins) from another blood type. Clumping together of RBCs.
agglutination
Agglutination forms dangerous clumps or fragments of RBCs causing a ___-_____. This can block small blood vessels of vital blood supply and damage tissues i.e. organs . Enough damage will make RBCs undergo ______.
cross-reaction, hemolysis
Drops of person’s blood are mixed with solutions containing antibodies. Clumping a.k.a. agglutination occurs where sample contains the matching antigen. e.g. type A blood clumps with anti-A antibodies
blood typing test
Blood typing tests are necessary to avoid _____ ______. Donor and recipient blood types must be _____ (will not cross-react).
transfusion reaction, compatible
This blood type clumps with anti-A antibodies. Does not clump with anti-B antibodies. Clumps with anti-Rh antibodies.
A+ blood type
blood type can receive from A+, O+, O-
A+ blood type
This blood type does not clump with anti-A antibodies. Clumps with anti-B antibodies. Clumps with anti-Rh (-) antibodies.
B+ blood type
