Blood
transfusion from person to person, severe reactions, sometimes fatal. This is
because human erythrocytes contain antigens or agglutinogens entering
transfusion reacted with antibodies (agglutinins). As a result, adhesion of
erythrocytes occurs. The severity of the reaction depends on the blood group of
the donor and
recipient.
The ABO blood groups, there are four: 0, A, B and AB.
People with
group AB are universal recipients, since they do not have blood agglutinin, and
can be any blood transfusion without fear agglutination reaction. People with
blood group 0 - is
universal
donors: in their blood no agglutinogens, and transfusion of it to others is not
accompanied by a group of incompatibility reactions.
Here is an
example of group (ABO) incompatibility.
Group B
erythrocytes to group B plasma - no agglutination. Red blood cells of group A
in plasma of group B - agglutination (bonding).
