    Blood types are defined by the antigens on the cells. There are A and B antigens. There are also A and B antibodies. A antibodies attack cells with A antigens, and the same with B.

    Your blood type (AB) means that your blood cells have A antigens and B antigens on their surface. As a result, they have neither A or B antibodies, as these would attack the cells. Since you have neither type of antibody, you can take ANY type of blood safely. However, only type AB blood people can take type AB blood transfusions.

    Type A blood means that the blood cells have A antigens on their surface, and B antibodies. Such blood types can only take Type A blood or Type O blood.

    Type B blood means that the blood cells have B antigens on their surface, and A antibodies. Such blood types can only take Type B blood or Type O blood.

    Type O blood has NO antigens on the cell surfaces, and A and B antibodies. Such blood is very useful, as EVERYONE can safely take Type O blood. However, if you have Type O blood, you can ONLY take Type O blood.

    If you take in blood that is incompatible with your blood type, you can die. Also, many diseases can be transmitted by blood transfusions.

    You might want to see this picture, it makes all the types easy to understand.

    And this picture makes compatibility easy to understand. Each type is compatible with itself.

    As for the +, it means that you are Rh Positive. This is good, because you will never have a child suffer from Rh disease. Rh disease is when an Rh negative mother has an Rh positive fetus growing inside her, and some of the fetus's blood gets inside the mother. The mother's body will develop anti-Rh antibodies, which may then attack the newborn.

    Without going into a full biology lesson this is how blood type works: A and B types are co-dominant genes, this means that you got an A from one parent and a B from the other. Now both of your parents could have been AB and you happened to get an A from one and B from the other. Or your one or both of your parents could have been A only or B only. The positive or negative is determined also by your parent's blood type. + is a dominant trait, meaning either one or both of your parents could have + blood. In short you only need one + gene to have + blood, so either of your parents could have given it to you.

    The reason your blood type is important is because antigens are structures on the outer wall of your blood cells. The letters and signs correspond to the type of antigens on your cells. Both your letter type (or ABO group type), and your +/- type (or Rh type) affect who can receive your blood, and what blood you can receive. Your body will reject blood with the wrong type of antigens.

    You are able to receive blood from pretty much anybody (A, B, AB, O) :]

    You are able to only donate blood to other AB people.

    You have a Rh Protein antigen in your blood, which makes it +.

    For an AB bloodtype that means you had to recieve a dominant A allele from one parent and a dominat B allele from the other parent, hot sure what the positive does though.
