A Patient With a Type O Blood Can Safly Receive
When you take a transfusion, it's better to receive blood of the same ABO and RhD blood group. Withal, in an emergency or special circumstance, if the aforementioned blood group isn't available, you might be given some other group then your immune organisation won't react.
Know your blood group essentials
Antigens are proteins or carbohydrates that our immune system tin can recognise.
Any antigen that's 'foreign' to our allowed system is destroyed by an antibody.
Antibodies are set on molecules our immune system makes to protect us confronting foreign things such as bacteria and viruses. Antibodies can also form in response to different blood groups. Everyone is born with some antibodies and develops others over their lifetime.
ABO is the major blood grouping organization and is genetically determined. Your ABO type depends on whether yous have A or B antigens on your red cells.
If you have the A antigen, yous have group A carmine cells.
Information technology's possible to have both A and B antigens, which ways the claret group is AB.
If you have blood type O, your cells don't take either blazon of antigen.
The Rh blood group system has around 50 different red blood cell antigens. D is the most important antigen of the Rh organization and it's also known as RhD.
In Australia, about 83% of people have the D antigen on their red cells, so their blood type is called RhD positive. The other 17% don't have the D on their ruby cells and are chosen Rh negative.
The percentage of Rh negative people varies in different countries. For example, less than 5% of India's population are Rh negative.
Some people who are RhD negative volition have an immune response to RhD and brand antibodies. These antibodies can destroy whatsoever red cells which are RhD positive. This may occur with a transfusion or when pregnant with an RhD positive baby. Knowing your RhD group is also very important for women who are or may become pregnant every bit the antibodies can cause bug for the mum and baby.
Because of the reasons above, information technology's best that patients receive red cell components of identical ABO group and RhD type in their transfusions.
Sometimes that'south not possible, like in an emergency when the patient's blood type is unknown and they need blood urgently.
In this example, O Rh negative is the universal red jail cell donor blood and can exist given to anyone with any blood type.
Safe blood types for each patient blood grouping:
| Patients blood group | Donor blood group |
|---|---|
| O- | O- |
| O+ | O-, O+ |
| B- | B-, O- |
| B+ | B+, B-, O+, O- |
| A- | A-, O- |
| A+ | A+, A-, O+, O- |
| AB- | AB-, A-, B-, O- |
| AB+ | AB+, AB-, A+, A-, B+, B-, O+, O- |
Plasma may comprise anti-A, anti-B or both anti-A and anti-B antibodies depending on your claret group. If you require plasma you should only receive plasma that doesn't contain an antibody which could set on the antigens on your own red cells.
Grouping A patients have A antigen on their red cells, so they can't receive group O or grouping B plasma every bit the anti-A will assail their red cells. Group B patients have B antigen on their red cells, and then they tin can't receive group O or group A plasma as the anti-B will attack their red cells.
Group AB recipients tin can only receive group AB plasma. Group O recipients don't have either A or B antigen, so can safely receive plasma of any claret group type.
| Patient group | Compatible plasma donor |
| A | A, AB |
| B | B, AB |
| AB | AB |
| O | O, AB, A, B |
ABO identical platelets are usually preferred. Still, in some circumstances, the need for other special requirements may be more important than providing the same ABO group.
Your healthcare team volition work this out and you can always talk to them if you'd like more than information.
