What is the ABO blood group?
The ABO blood group system is the most important blood type classification system for humans . Simply put, the labels O, A, B, and AB indicate whether the antigens A and B are present on the red blood cells of a person (O stands for “no antigens”, while AB means that both are present).
Is O-type blood compatible with all other blood types?
The immune system of the recipient may react (often fatally) to the presence of antigens that are not supposed to be present in the blood; in particular, O-type blood is compatible with all other blood types (since no antigens are present), whereas AB-type blood is only compatible with AB (since both antigens are present).
Blood types and Rh factor by country

What does Rh negativity mean for pregnancy?
If you are Rh-negative and pregnant, then there is a possibility you may get sensitized during pregnancy or delivery, and this can affect your next pregnancy. When Rh-sensitized, your body can create antibodies that could conceivably cross the placenta and attack the fetus' red cells.
Which blood type has the highest prevalence in Europe?
The listing of blood type percentages simply lists the continent where each blood type is the most common. In this synopsis, Type A has the highest prevalence in Europe and Central Europe, Type O has the highest prevalence in the Americas, Type B and Type AB have the highest prevalence in Asia.
What is the most common blood type?
The global distribution of Blood Type O: the most common blood type.
What Is Blood Type?
Composed of sugar molecules, these antigens are called agglutinogens. There are two types of agglutinogens: type A and type B. The type of antigen on the surface of your red blood cells determines your blood type.
Why did blood transfusions result in death?
Blood transfusions often resulted in death, as the receivers immune system would attack the foreign, unmatched blood that was transfused.
What is the blood type of a person with Rh factor?
There is another protein (called Rh factor) that is sometimes found on red blood cells. If a person has Rh factor, their blood type is called “Rh positive.”. An individual lacking this protein is called “Rh negative.”.
What are the different types of blood?
Type A: The red blood cells have the type A agglutinogen. Type B: The red blood cells have the type B agglutinogen. Type AB: The red blood cells have both type A and type B agglutinogens. Type O: The red blood cells do not have any agglutinogens at all. ...

How are blood types determined?
Blood types are determined by the presence or absence of certain antigens – substances that can trigger an immune response if they are foreign to the body . Since some antigens can trigger a patient's immune system to attack the transfused blood, safe blood transfusions depend on careful blood typing and cross-matching.
Why is Type O blood so common?
Type O is routinely in short supply and in high demand by hospitals – both because it is the most common blood type and because type O negative blood is the universal blood type needed for emergency transfusions and for immune deficient infants .
