Giving blood?

[The_Punisher]

Quick run down of blood types (written by me).

You have two kind of proteins in your blood that is just genetic.

The first is the letter protein. You have A type of blood. You have B type of blood. Both are proteins in the same slot, but are different. You can\'t give an A person type B blood. The A person\'s blood will see the B protein and reject it.

Now there\'s AB blood which is a combination of both the A and the B blood at the same time. You can put either straight A or straight B blood into this person and his body won\'t reject it.

Lastly, there\'s O type. This isn\'t actually a protein, but a lack of a protein. It just isn\'t there. So if you put O type into an A or B person, their blood won\'t see a foreign protein and won\'t reject it.


The next protein type is either + or -. Meaning it\'s there, or it isn\'t. You can put - blood into + blood person, but not the other way around. A - blood person will reject + blood.

So you have Types like AB-, or O+, or B+ and so on and so on.

O- have no identifying proteins, so it can be put into all people without rejection. But the O- can only recieve O- blood.

On the other side of the spectrum, a person with blood AB+ can only give blood to other AB+ people, but can recieve blood from everyone.

So in a hospital, if you need blood, they stick O- in you until they are sure of your blood type.


I myself, am an A+.
