  BloodGivers.com --- Blood Types and Compatibility
A person with Blood Group A is so because he has antigen A. Antigen B makes a person's Blood group B. If a person has both antigens, he is group AB and if he has neither, the blood group is O. Antibodies against these two Antigens are found in the blood Plasma.
For example, Blood Groups A, B, AB and O have Antigens A, B, AandB and None respectively.
For example if a person of blood group A is given blood from a donor with blood group B, his anti B Antibodies will stick to the B Antigens on the ‘imported’ red blood cells entering his body.

 The Blood Group Diet Review
His theory is based on the idea that each blood group has its own unique antigen marker (a substance that the body recognises as being alien) and this marker reacts badly with certain foods, leading to all sorts of potential health problems.
Blood Group AB People with this rare blood type should eat a combination of the foods recommended for blood groups A and B. Somewhat confusing when type B allows you to eat most foods, while type A suggests a vegetarian diet!
There are also several concerns, namely that the diets recommended for blood groups O and A are considerably limited and cut out major groups of foods.

 The National Blood Service - what blood type are you?
Blood group B means you have B antigens, while group O has neither, and group AB has some of both.
The anti-A antibodies in group B attack group A cells and vice versa.
And so it goes for groups B, AB and O. This effectively doubles the number of different blood types to be matched, because you shouldn't mix blood type A+ with blood type A-.

  Blood Groups, Blood Typing and Blood Transfusions
If you belong to the blood group 0 (null), you have neither A or B antigens on the surface of your red blood cells but you have both A and B antibodies in your blood plasma.
The B antibodies in the A+ blood bind the antigens in the B+ blood and agglutination occurs.
For a blood transfusion to be successful, AB0 and Rh blood groups must be compatible between the donor blood and the patient blood.

  Bloodindex - Blood Group Systems
Blood group antigens are components of the red cell membrane and are immunogenic.
Although the ABO blood group system was the first to be discovered, it remains the most important system in transfusion practice because of the invariable presence of naturally occurring anti-A and anti- B antibodies (agglutinins) in persons lacking the corresponding antigen.
Group A individuals have anti-B agglutinins in plasma and group B individuals have anti-A agglutinins.

Blood transfusions were not possible until Karl Landsteiner first identified the major human blood groups -- namely O, A, B, and AB -- in a series of experiments in 1901 that earned him the Nobel Prize.
The ABO blood groups are defined by specific inherited molecules, or antigens, that are present on the surface of red blood cells.
If group A red cells are mistakenly transfused to a group O recipient, for example, the anti-A antibody in the recipient's plasma destroys the transfused group A cells and a serious transfusion reaction occurs.

The primary function of red blood cells is the transport of oxygen and carbon dioxide between the lungs and the peripheral tissues.
If a person with type A blood requires a blood transfusion and is given type B cells, those cells are immediately encountered by antibodies recognizing them as foreign, which cross-links them and prepares them for destruction by the body.

 Bloodindex - What are blood groups
Blood groups are individual differences in proteins and/or carbohydrates that make up part of the red blood cell membrane.
However, by the late 1940s the single letter blood group antigens became in short supply and a new approach was taken.
The D and K antigens had already been assigned and were too similar, so the new blood groups became Duffy (Fy) and Kidd (Jk).

The EldonCard blood typing kit uses the basic forward antibody method of blood hematology to easily and quickly provide the user with their blood type (A, AB, B or O) and rhesus factor (Rh negative or Rh positive) in a few minutes without the need for special laboratory supplies or training.
Blood typing is determined by the type of antigens or markers that are on the surface of red blood cells (either "A" or "B") and if there are antibodies to a portion of the blood type known as the Rh factor (either "positive" or "negative").
Blood type is inherited from and dependent upon, the blood type of an individual's parents.

 Blood Cancer & Peripheral Blood Cell Transplants - National Cancer Institute
Transplants of special cells in the blood stream may be more effective than bone marrow transplants in patients who receive high-dose chemotherapy for blood cancer, according to a large randomized trial reported in the New England Journal of Medicine on January 18, 2001(see the journal abstract).
One of the major goals of the trial was to compare the two groups in terms of risk of graft-versus-host disease (GVHD), a common and sometimes fatal complication of allogeneic transplants in which the patient’s immune system attacks the transplant.
Their blood counts -- the numbers of white blood cells and platelets -- returned to normal levels five or six days faster and they required fewer transfusions of platelets.

 Blood Type - blood group and Rh status information
When your practitioner tells you your "blood type," you are being given two pieces of information - your blood group and your Rh status.
Your blood group will be A, B, AB, or O. If you have "A" "B" or "O" blood group, you have antibodies in your blood plasma that destroy some of the other blood groups.
While knowing your blood type can be useful information, a transfusion of blood cells is never done unless your blood is rechecked for blood type and tested with the donor blood in order to ensure that it is compatible.

 Blood Type and Rh
If you have group "A" blood, you cannot receive blood that is group "B" and vice versa.
You may have group "A" blood, but have genes for both groups "A" and "O." Because "A" group is stronger or dominant, your blood will be group "A." However, you can give your children genetic material for either group "A" or "O." The same is true of "B" group.
O, A, B, AB Rh status is similar to blood groups.

Usually, when we say someone has a rare blood type, what we really mean is that there is something special about their blood that goes beyond the ABO blood typing system (learn more about rare blood types here).
The ABO blood group is comprised of four blood types: O, A, B and AB.
After blood is drawn, it is tested for blood type and Rh type (positive or negative), as well as for any unexpected red blood cell antibodies that may cause problems in the recipient.
