We all know that except universal donor, any blod exchange between two individuals should only be done with the same blood group between the two isn't it? now, what if abperson having A+group of blood is given B+ group blood? any views here?

The danger of having a mismatched blood would result to formation of a clot as there will be clumping of blood cells or there will be hemolysis (Red Blood Cell Destruction). It is not a practice nowadays to give blood type O to the other blood groups. A common misconception is that Blood Type O (Universal Donor) and Blood type AB (Universal Recipients). This is a misconception because Type O also has antibodies against A and B blood types and AB has no antibodies but they have surface receptors for Anti-A antibodies and Anti-B antibodies. For example: A donor with blood type O and a recipient with blood type A. Blood type A Red Blood Cells have receptors for the Anti-A antibodies present in Blood type O so there is a danger of these blood cells to clump to each other. The best actually when giving a blood transfusion is that the blood types should always be matched that is Blood Type A should only accept from another Blood Type A, B should only receive from a blood type B. Now, for the + and -; You are said to be positive if your Red Blood Cells have Rh antigens(receptors on the surface of RBC) and negative if you have none. Now for these blood groups it is different when it comes to blood transfusion. A+ can accept blood from an A- blood donor as long as this is the first time he/she receives from an A- blood as the A+ recipient still has no antibodies against A- blood. The second time that A+ needs another blood transfusion it can not already accept blood from an A- donor as the antibodies of A+ will attack the A- RBCs. I hope this is not a little bit too complex alienstar. If you want a more infromation you can post me a message and I'll further explain as I've already taken much space in your discussion lol.

Clotting...! oh...you mean mismatch of blood will lead to clotting of blood .is it so? Till now i thought blood group "O" can be given to any blood group patients and here you have given out detilas and cleared out misconception of mine.People who have taken up medicine will be able to explain things in detail isn't it? by the way, what is your profession? have you also taken up medicine as i am really thankfull for this usefull response of yours. Anyway's, thanks for responding

Yes, blood clotting will occur as there is still clumping of the two blood types. Even if the Blood Type has no receptor for the antibody present in BT A the antibody of BT O would still react that is it would still atttach to the receptors of blood type A. I'm talking about the antibodies because an antibody would always react to a specific antigen (surface receptors of cells). Since BT O has antibodies against BT A blood cells.

There will be a major transfusion reaction and the red cells would break up and the person will become severely anemic. This can also lead to DIC etc. As the process can be massive it can cause the kidneys to fail, the BP to drop etc. In the modern medical world, its criminal for such a thing to happen!

Hm...you are the first person here to come out with the effects that may result in wrong blood transfer to a patient and what do you mean by DIC here as i haven't heard about this before and as you said, maybe kidney failure will occur here isn't it? and definitely it is a crime for sure and thanks for giving little things on this here... Anyway's, thanks for responding

It can effect badly to that patient if wrong blood is given to him. It will create reaction.

Yes, we all know that if a difefrent blood group is given to a person who is not having the same blood group given to him , it will lead to complicationas for sure and i doubt that the effect maybe a question of his life also as i am not sure about this nor you also isn't it? but, interesting to know the result... Anyway's, thanks for responding

This is due to the reason that, the blood of A Group people contains anti - B antibodies. In B group people there are anti - An antibodies. If we give A group blood to a B group patient, it is bound to be incompatible and will result in serious consequences. Hope this be of help.

Yes, theer are different blood groups in human beings and except universal group all others will be different.So, in actual practice A+group people cannot be given B+ group blood for sure as you said it will lead to serious consequences for sure and what consequence it will lead we are not at all sure.... Anyway's, thanks for responding
