    In some ways, every person's blood is the same. But, when analyzed under a microscope, distinct differences are visible. In the early 20th century, an Austrian scientist named Karl Landsteiner classified blood according to those differences. He was awarded the Nobel Prize for his achievements.

    Landsteiner observed two distinct chemical molecules present on the surface of the red blood cells. He labeled one molecule "A" and the other molecule "B." If the red blood cell had only "A" molecules on it, that blood was called type A. If the red blood cell had only "B" molecules on it, that blood was called type B. If the red blood cell had a mixture of both molecules, that blood was called type AB. If the red blood cell had neither molecule, that blood was called type O.

    If two different blood types are mixed together, the blood cells may begin to clump together in the blood vessels, causing a potentially fatal situation. Therefore, it is important that blood types be matched before blood transfusions take place. In an emergency, type O blood can be given because it is most likely to be accepted by all blood types. However, there is still a risk involved.

    A person with type A blood can donate blood to a person with type A or type AB. A person with type B blood can donate blood to a person with type B or type AB. A person with type AB blood can donate blood to a person with type AB only. A person with type O blood can donate to anyone.

    A person with type A blood can receive blood from a person with type A or type O. A person with type B blood can receive blood from a person with type B or type O. A person with type AB blood can receive blood from anyone. A person with type O blood can receive blood from a person with type O.

    Because of these patterns, a person with type O blood is said to be a universal donor. A person with type AB blood is said to be a universal receiver. In general, however, it is still best to mix blood of matching types and Rh factors.

    personally, im either a AB or O.

    I am O negative I believe. Genetics determines blood type. AB is the universal acceptor (meaning you can receive blood from everyone) while O is the universal donor (can give blood to everyone)

    Blood type is determined by the ABO blood group anitgens present on red blood cells. If you have A blood, your red blood cell type is A and your blood has Anti-B antibodies. Group AB has both A and B red blood cell types and no antibodies present (which is why it is the universal acceptor). Group O has O red blood cell types and BOTH anti-A and anti-B antibodies (cannot accept blood other than O). If the Rhesus group is present, your blood is classified as positive (if not than your negative)

    If you go to http://en.wikipedia.org/wiki/Blood_type there is TONS more information.

    There are 3 blood "factors".

    1. "A"

    2. "B"

    3. "Rh"

    You have all 3 factors, therefore you are a "universal recipient". You can receive blood from anyone. Your type is determined by your parents. You inherited your blood type from them. One parent gave you the "A" factor, the other parent gave you the "B" factor, and one or both parents gave you the Rh factor. A "universal donor", one who can donate to anyone, has type "O -" blood. Such a person has none of the 3 factors to give to someone else, so there won't be a mismatch.

    You can only donate blood to another "AB+" person.

    O positive

    Your blood type is determined by the genes you carry - which in turn tell your body to make different proteins and thus when you express different protein antigens on the surface of your blood cells, this gives you a blood type.

    There are many different systems of blood type. The most important ones in terms of blood transfusion are the ABO blood groups and the Rhesus blood groups

    Using this system: people who have no antigens on their blood cells (O and Rh negative: hence O negative) can give their red cells to anybody, because these cells do not have the flags that identify to another person's immune system that they have come from a different person.

    People who have AB positive do not have make any antibodies and can therefore receive blood from any blood type.

    Use this table to predict reaction (Y) (ie. UNSAFE) or no reaction (N) (ie SAFE to transfuse)

    Donor: O- O+ A- A+ B- B+ AB- AB+

    Recipient

    O-.........N...Y....Y....Y....Y...Y....Y......Y

    O+........N...N....Y....Y....Y...Y....Y......Y

    A-.........N....Y....N....Y...Y...Y....Y......Y

    A+........N....N....N....N...Y...Y....Y.....Y

    B-.........N....Y....Y....Y....N...Y....Y.....Y

    B+........N....N....Y....Y...N...N....Y.....Y

    AB-......N....Y.....N....Y...N...Y....N.....Y

    AB+.....N....N....N....N...N...N....N.....N

    Odd - sorry the table seems to come out funny

    Note that Rhesus negative people may initially get no reaction from an initial transfusion of Rh positive blood if they have not yet developed antibodies against Rh positive blood cells. This seems to be the case in a good many Rh neg people. In the ABO blood group, most people have already developed antibodies against the A or B antigens as determined by their blood type.

    I got this piece of information from the website below. btw, i`m O positive.

    A person with type A blood can donate blood to a person with type A or type AB. A person with type B blood can donate blood to a person with type B or type AB. A person with type AB blood can donate blood to a person with type AB only. A person with type O blood can donate to anyone.

    A person with type A blood can receive blood from a person with type A or type O. A person with type B blood can receive blood from a person with type B or type O. A person with type AB blood can receive blood from anyone. A person with type O blood can receive blood from a person with type O.

    Maybe this can help you. or go to the website below to find more info.hope this helps.

    level am also AB positive. The Rh level in your blood is the determining factor.

    I'm O positive, I can give my blood to any blood type, but I don't know what your blood type can receive or give too. But you have a rare blood type. :].. I think... O.o
