red blood cells have protein embedded in their membranes.

people make antibodies against these proteins - except the ones they already have.

thus, a doners and a recipients blood "type" must match.

There's more ... but it'll start you off.

What risks for a recipient in a blood transfusion are there?

The blood given by transfusion must be matched with the recipient's blood type. Incompatible blood types can cause a serious adverse reaction (transfusion reaction). Blood is introduced slowly by gravity flow directly into the veins


Why must be blood before ablood transfusion?

Blood typing is crucial before a blood transfusion to ensure compatibility between the donor's and recipient's blood. If incompatible blood types are mixed, it can lead to severe immune reactions, potentially causing life-threatening complications. Testing for blood type and cross-matching helps prevent these adverse reactions, ensuring the safety and effectiveness of the transfusion.


Do blood types have to be matched before blood can be transfused?

Yes, blood must be transfused into a body with the same blood type. If blood is transfused into a body with a differing blood type , the body may become ill and fight to kill the differing DNA.


What needs to happen for blood transfusion to occur?

For a blood transfusion to occur, a compatible donor's blood must be matched with the recipient's blood type to prevent adverse reactions. Prior to the transfusion, blood samples from both the donor and recipient are tested for compatibility, typically using ABO and Rh typing. The procedure requires medical supervision to monitor for any potential complications or reactions. Once compatibility is confirmed, the blood is administered through an intravenous line.


Why is blood type checked before a tranfusion?

Blood types must be matched specifically except of the case of O neg. which I have.


If type O blood is transfused into a person with blood type B what will need to be done to the blood?

Since a patient with Type B blood has B antigens on their RBC's and since Type O blood has both anti-A and anti-B antibodies present in the blood plasma, the donor blood needs to be treated before transfusion. The Type O blood needs to be separated into packed cells and plasma, usually done by centrifuge, and only the packed cells should be used for the transfusion. Remember the anti-B antibodies are present in the Type O blood plasma and could cause serious damage in the system of a patient with Type B blood.


Can a dog get a blood transfusion from cats blood?

This belief is common enough that I've heard it before, but in fact it's generally a very bad idea to attempt to transfuse blood across species. Cats have three blood types (A, B, and AB)... they don't have anything like the human "Universal Donor" O type, so transfusions for cats must be cross-matched.


Can blood be drawn during transfusion?

No, blood cannot be drawn during a transfusion as the purpose of a transfusion is to provide blood to the patient, not to remove blood from them. Drawing blood during a transfusion would disrupt the process and potentially cause harm to the patient.


What precaution should be taken during blood transfusion?

no air bubble must get in


What are the hazards of incompatible blood transfusion?

Risks associated with autologous blood transfusion include transfusion reaction if an allogeneic blood transfusion was inadvertently given and transmission of infectious agents if the blood became contaminated.


Why must blood be matched before a blood transfustion?

you have a certain blood type, and if you get a bloodtype that doesn't math yours or is able to cooperate with yours you body could reject it and it could make you sick. ~Rae


What is blood type exactly?

Blood type is the composition of your blood. Every blood type is different. In order for your body to accept blood in a transfusion, you must receive the blood that is compatible with you.
