what will happen after a mismatch in the blood type?

Answer 1

the blood will be worthless and the person will have a severe reaction against it, most likly. It can be dealy, if the amount is large.

Answer 2

Agglutination!!
What is agglutination you ask? It is clumping of blood together. This will occlude blood vessels and damage end organs.
Why does this happen? well because each cell in our body contains an antigen. When it comes to blood, we have A and B antigens. We have antibodies (think of them as assassins) for any antigen which is not self. Some people have just one of these antigens in their blood, like A, others have B, yet others have both ( AB) or some have neither (we call those type O) In any case, whenever we come in contact with a non self antigen, our antibodies will try and DO destroy it, That causes the clumping of blood which is called agglutination.

Answer 3

A mismatch blood always leads to agglutition.

Answer 4

In a serological cross-match red blood cells from the donor unit are tested against the plasma/serum of the patient who is in need of the blood transfusion. If the patient’s serum contains antibodies against the antigens present on the donor red blood cells agglutination will occur. Agglutination is considered a positive reaction indicating that the donor unit is incompatible for that specific patient. If no agglutination occurs the unit is deemed compatible and is safe to transfuse.
Please see the webpages for more details on Cross matching (Blood typing).

Answer 5

acute HTRs. Other blood group incompatibilities (most notably with Rh antibodies like D, E, and c, and Kell antibodies), faulty blood warmers, infusing blood with a hypotonic solution like 0.45% normal saline, and a variety of other mechanical problems can potentially cause acute hemolysis. Fortunately, though, most of the "other" methods of acute hemolysis usually do not have the devastating consequences typical of an ABO mismatch.

Answer 6

Death.

wat happens is, blood coagulation happens. The donor's blood will be destructed by the receiver's plasma due to the antibody (agglutinins) present in the body of receiver.

Answer 7

Need more info. For what? Blood transfusion? Paternity test? What?

Answer 8

antibodies in the body will attack the foreign red blood cells and cause it to rupture (haemolysis) and cause massive release of iron, potassium and calcium into the blood stream

in severe cases it can cause cardiac arrest and renal failure

Answer 9

If the wrong blood type enters your bloodstream then your body will attack it, eventually leading upto a clogin the veinand you can die from it, especially if its clogged in the brain.Thats called a stroke.

Answer 10

When someone is given the wrong blood their WBCs raise to try and fight what they think is an infection...causing coma or even death.
