Why can't blood type not be transfused? Which blood types can transfuse each other?

Blood transfusion can only be carried out if the blood type is suitable. Then why is the blood type suitable so important? Why can't blood transfusion be carried out if the blood type is not suitable? Next, let's have a look with sihai.com.

Why can't blood type not be transfused? Which blood types can transfuse each other?

Plasma contains agglutinin which can play a binding role, while red blood cells contain agglutinin which can be bound. There are two kinds of lectins, a and B; there are also two kinds of lectins, & alpha; and & beta;. A and & alpha;, B and & beta; are two pairs of enemies. When they encounter each other, they will 'fight' and twist together to produce agglutination reaction.

There are four blood types. Type A: erythrocyte contains agglutinin A and plasma contains agglutinin & beta;; type B: erythrocyte contains agglutinin B and plasma contains lectin & alpha;; type AB: erythrocyte contains agglutinin A and B, and plasma does not contain any agglutinin; type O: erythrocyte contains no agglutinin, plasma contains lectin & alpha; and & beta;.

During blood transfusion, if the blood type does not match, the agglutinin a in the input blood meets the lectin & alpha; in the patient's plasma, or the agglutinin B in the input blood meets the lectin & beta; in the patient's plasma, the agglutination reaction will occur, which will lead to the shrinkage and deformation of the red blood cells and cause life-threatening. Therefore, blood group incompatibility must not be transfused.
