AB blood type refers to the antigens present in the in the blood (antibody generator).

The three general types are A B O. A refers to a person who only has A antigens in the blood, B is refers to B antigens and O means the blood produces neither.

A person with AB has all the possible antigens that would cause the body to have an immune response to. Since it has both A and B the body will not attack these antibodies.

This is the same reason O is a universal donor, since it contains none of the antibodies to trigger an immune response.

A and B are antigens that are on the surface of red blood cells. People have one, both, or none. If you don't naturally produce the antigen, your body's white blood cells will attack and destroy red blood cells that carry them.

So if a person with type A blood is injected with type B blood, the body of that person will attack the type-B blood cells.

A person with AB positive blood is a universal receiver, because they already produce all of the normal antigens present on red blood cells. So a AB+ person's body will not attack red blood cells that carry some, all, or none of the antigens. Likewise, O- is called the universal donor, because it lacks all antigens. So no one's body will recognize it as foreign.

I don't think, I know. The reason the AB blood type is called the universal recipient is because people with AB type blood can receive blood from people with A, B, or O type blood - provided it's the same Rh... a person with AB positive blood could receive blood from someone with AB, A, B, or O positive blood, but not from someone with AB, A, B, or O negative blood and vice versa.

Type O is considered the universal blood type.


What blood types can an AB blood type recieve blood from?

A negative, B negative, AB negative, or O negative"As far as I can tell AB negative can only receive AB negative. It is one of if not THE rarest blood type. You can find out for sure by looking up blood types on Google I think I went to wikipedia the last time I checked."For information we cannot rely on wikipedia, because it can be changed by anyone :=)And the answer for your question is AB- can receive all blood type with rhesus negative (A-, B-, O-, and AB-)It is the rarest type only 0.7% people have this type, but in term of recipient is not.O- is the only one can receive O-.Basically blood type with (+) can receive (+) or (-), andblood type with (-) only can receive (-). That is why O- is the hardest in term of blood transfution.


What blood type is the universal donor?

Type O, since it contains no antigensType O, negative, to be more speciifc (with negative referring to the Rh factor)O NegativeIs widely considered the universal blood type. It is very important because it potentially be transfused to any patient regardless of their blood type. Especially in emergency situations, when there isn't enough time to determine a patients blood type.

Can AB donor be transfuse into a type O recipient?

While type O blood is known as being the universal donor, it is not a universal recipient. Type O blood can be transfused into any other blood type, but someone with type O blood could only receive a transfusion of type O blood.

Was ask by doctor to let your wife know you are o- why?

This is a really basic answer. There are four blood types, A AB, B and O. There are positive and negative versions of each. If a person needs blood (for an operation, maybe, or if they got injured and bled a lot), the blood types have to be compatible or the person will die. "O negative" blood is known as the "universal donor" blood because it doesn't conflict with any of the other types. "AB" is known as "universal recipient" blood because any of the four blood types can be used. If you have O negative blood, you should be able to give your wife blood if she needs it for a transfusion. (I think O negative is the most common blood type, by the way. AB is the rarest.)
