Your blood type, also known as your blood group, helps determine what kind of blood donation might be best for you to give.

Donations by blood type
Even if you can’t give a particular kind of blood donation for health or other reasons, keep donating what you can. Your donation will still save lives!
How do blood types work?
You inherit your blood type from a mix of your parents’ genes. There are eight main blood types, organised through two combined systems. These systems are ABO (blood types A, B, AB or O) and Rhesus type or group (positive or negative).
Your blood type is a combination of these two systems. For example, by percentage of population, the most common blood type in Australia is O positive and the least common is AB negative.
Why are blood types important?
When someone is given a blood transfusion, it’s best to give them blood that’s the same type as their own. If that isn’t available, they can be given certain other compatible blood types depending on their own blood type.
Some blood types are ‘universal’, which means they can be given to anyone. O negative red cells can be given to anyone, and are often used in emergencies. AB plasma, positive or negative, can be also given to anyone.
