The ABO system consists of A, B, AB and O blood types.
People with type A have antibodies in the blood against type B people with type
B have antibodies in the blood against type A, people with type AB have no
anti-A or anti-B antibodies. People with O have both anti-A and anti-B
antibodies, people with type AB blood are universal receptors because they can
receive any of the ABO types. People with type O blood are called universal
donors, because their blood can be given to people with any of the ABO types
(WebMD, 2012).

The ABO blood types is the only blood group system in
which antibodies are consistently, predictably and naturally present in the
serum of people who lack the antigen. Therefore ABO compatibility between donor
and recipient is crucial since those strong, naturally occurring A and B
antibodies are lgM and are readily activated, complement and cause
agglutination. If ABO antibodies react with antigens in vivo, result is acute
haemolysis and possible death (Schroede and Jensen, 2013).

Rhesus Blood Group System
The Rhesus blood group system is one of the current human
blood group systems. It is the most important blood group consists of so
defined blood group antigen. The commonly used terms Rh factor, Rh positive and
the Rh negative refer to the D antigen only. The D antigen is used to determine risk of haemolytic disease of
the newborn as prevention is the best approach to the management of this
condition. If the Rh antigen is present, it is called Rh positive. Rh negative
children can have parents that are either positive or negative. If parents are
Rh negative then the children will be Rh negative (Levine, 2002).
