The other blood typing system commonly used is the Rhesus system, also called Rh system, named after the Rhesus monkey in which it was first discovered. In this system, if you have an antigen called the RhD antigen on the surface of your red blood cells, you are said to be Rhesus positive (Rh+). If you don’t, you are said to be Rhesus negative (Rh-). In Australia, about 83% of people are Rh positive.
Combining your ABO blood group with whether you are Rh+ or Rh- means your blood can be classified as one of 8 possible types:
O positive (O+)
O negative (O-)
A positive (A+)
A negative (A-)
B positive (B+)
B negative (B-)
AB positive (AB+)
AB negative (AB-)
The most common blood group in the Australian population is O positive, with about 40 per cent of people having this blood type. On the other hand, only about 1 per cent of Australians are AB negative – the least common type.
One difference between the Rhesus system and the ABO group system is that Rh negative people don't usually possess antibodies against RhD (unless they have been previously exposed to it), whereas in the ABO group system if the antigen is absent from the red blood cell, the antibody against it is present in the plasma.
Testing to see if you are Rh positive or Rh negative is routinely done during pregnancy, and for blood donors and for people receiving a blood transfusion.
If a mother is Rh negative but her baby is Rh positive (which can happen if the father is Rh positive), the mother could produce antibodies that fight the baby’s red blood cells. This can happen if blood from the unborn baby enters the mother’s circulation. When there is a risk of this happening (threatened miscarriage, termination, chorionic villus sampling (CVS), abdominal trauma, at delivery), an injection called anti-D can be given to the mother to help prevent these antibodies against Rh positive blood being produced. According to the Australian Red Cross Blood Service 17% of Australian mothers.
