As you probably know, we all have a blood type. But do you know what makes each type unique? Show
While several blood group systems are used to type your blood, ABO is the most important. Your ABO type is based on the presence or absence of two antigens (A and B) on the surface of red blood cells. There are four ABO types: A, B, AB and O. Your blood type is also determined by Rh status: Rh+ or Rh-. That leaves us with eight possible blood types:
Each of these eight types is unique. Blood types determine who you can give blood to and receive blood from. Which type of donation is best for you is determined by your blood type, as well as patient need. Read more to find out what makes your blood type special: Your blood type is determined by genes inherited from your parents. Whether your blood type is rare, common or somewhere in between, your donations are vital in helping save and improve lives. You can register online to give blood How rare is A positive blood?
1 in 3 donors is A positive Around 30% of donors have A positive blood, making it the second most common blood type after O positive (36%).  Who can receive A positive blood?A positive and AB positive people A positive red blood cells can be given to people with:
What blood can A positive people receive?Groups A and O People with A positive blood can receive donations from:
Why is A positive blood important?It's always in demand A positive makes up almost a third of requests for blood from hospitals so we need to maintain a regular supply. Platelets from A positive donations are also important. Last year more A positive platelets were issued to hospitals than any other blood type. Find out about donating platelets Why is AB positive blood important?Although the need for AB positive red blood cells is falling, the demand for AB positive plasma hasn’t changed. To avoid wastage while ensuring the correct balance of plasma and red cells from AB positive donors, we manage donations differently to other blood types. Fresh frozen plasma is only produced from male donations. This is because female donors (especially those who have been pregnant) can develop antibodies that, while no danger to themselves, can prove life threatening to patients transfused with their plasma. We can generally meet the demand for frozen plasma and most red cells from our male donors, which is good news. We encourage our male donors to donate as frequently as possible but ask that female donors wait to donate until contacted directly by us. There are occasions when demand for AB positive rises. During these times we contact our female donors directly and rely on their support to ensure patients continue to receive the blood and blood products they need.
Whose type can you match?Donors with type O- blood are universal red cell donors whose donations can be given to people of all blood types. Donors with types AB- and AB+ blood are universal plasma donors, while patients with type AB+ are universal red cell recipients because they can receive red cells from all types. All other donors and recipients must be safely matched, for example:
