Why is it important to have compatible donor and recipient blood types in blood transfusions?

Answer 1

When the recipient receive the blood, it must be the same type of blood because when there is another flow of blood with the different types, the two types of bloods won't join together, and will cause serious sickness.

Answer 2

because your body will fight against the other blood type if it is different, and this is due to anti-body blood transfusion system.

for example if your blood type A and you take blood type B, your body will start producing anti-bodies against the new one, because it consider it as a foreign material.

but you can take ( O ) blood type what ever your blood type is, because ( O ) doesn't have any anti-bodies, and so your body will not consider it as foreign substance.

this subject is somehow complicated, can't be summarized in one question, you can read about ABO system, it may help you to understand the strategy :)

Answer 3

The more compatible the donated blood is to the recipient, the less the immune system attacks the donated blood. Major and minor blood types( ABO, Rh but also Duffy, Kell, Lewis,) help determine compatibility.

If you were to receive incompatible blood, your immune system attacks the blood cells. This destroys most of the transfused cells and results in a severe immune reaction in your body that can harm you, (fever, allergy etc.)

Answer 4

If there is not a proper match, the chance of rejection is very high. Rejection of the organ means that your immune system views the organ as foreign and attacks it, rendering it useless to the individual.

Answer 5

Because incompatible blood transfusion leads to destruction of the red blood cells (hemolysis) which occurs rapidly and can lead to death.

Answer 6

if it not done than agglutination can occur.
