What is a Blood Type test?
The Blood Group, RH Type test is used to determine your specific blood type. The presence (or lack thereof) of ABO and Rh antigens will determine the blood type letter and whether it is positive or negative.
The importance of knowing your blood type is to prevent the risk of you receiving an incompatible blood type at a time of need, such as during a blood transfusion or during surgery. If two different blood types are mixed, it can lead to a clumping of blood cells that can be potentially fatal.
There are four ABO antigen markers that determine blood group: A, B, AB, and O.
Type A blood (contains the A antigen marker) – this means that the liquid portion of your blood (plasma) has antibodies that will attack type B blood
Type A-negative (A-) blood – has the A antigen marker only; 6% of the population
Type A-positive (A+) blood – has both the A and Rh antigen markers; 36% of the population
Type B blood (contains the B antigen marker) – means your plasma antibodies will attack type A blood
Type B-negative (B-) blood – has the B antigen marker only; 2% of the population
Type B-positive (B+) blood – has both the A and Rh antigen markers; 8% of the population
Type AB blood (has both A and B antigen markers) – means your plasma does not have antibodies against either type A or type B blood
Type AB-negative (AB-) blood – has the A and B antigen markers; 1% of the population
Type AB-positive (AB+) blood – has the A, B, and Rh antigen markers; 3% of the population
Type AB-positive blood contains all the antigen markers, which means that it does not have antibodies against any other blood type. Because it will not trigger an attack on any other blood type transfused into it, type AB-positive blood is commonly known as the “universal recipient” blood type.
Type O blood (has neither the A nor B antigen markers) – means your plasma antibodies will attack both type A and type B blood
Type O-negative (O-) blood – has no antigen markers at all; 7% of the population
Type O-positive (O+) blood – has the Rh antigen marker only; 37% of the population
