What will it help you with?

It is essential that everyone know their own blood group and that of their family members. There are many occasions when knowing your blood group could be important, for example, if you or a member of your family, required an urgent blood transfusion it would be useful to know your blood group in advance. If it was an uncommon group it would allow the hospital valuable time to ensure adequate supplies.

If you travel overseas carrying a blood group card could prove invaluable. Accidents and other emergencies can often be dealt with more efficiently knowing the blood group of the person or persons involved.

Blood grouping is essential for safe blood transfusions. A patient must receive a blood type that is compatible with their own blood type. If the blood types are not compatible, red blood cells will clump together, making clots that can block vessels and cause death.

Who is it for?

We believe everybody should know their Blood Group whether young or old.

What does it Do?

In general a person with type A blood can donate to a person with type A or AB. A person with type B blood can donate to a person with type B or AB. A person with type AB blood can only donate to a person with AB only and someone with O type blood can donate to anyone. This is because type O blood has no antigen on its surface and is often called a universal donor. Blood type AB is the universal recipient as they can receive red blood cells of any ABO type. In an emergency if there is no time for blood grouping the person in need of a transfusion would be given type O blood.

Another blood group system involves Rhesus factors. The name Rhesus comes from the Rhesus monkeys in which the protein was first discovered. Rhesus factor D, the most important, is found in the blood of 85% of people, they are known as Rhesus positive. The remaining 15% are Rhesus negative. So people can be classified according to both systems, for example AB positive or O negative.

The Rhesus factor is important during pregnancy, a baby’s life can be endangered if it inherits a Rhesus positive blood type from its father while the mother is Rhesus negative. This is because the mother can form antibodies against the baby’s blood.

Here is a list of the blood types and their frequency in the UK population :

O Rh (D) Positive


O Rh (D) Negative


A Rh (D) Positive


A Rh (D) Negative
