Part 2: Red Blood Cell Types : Primary Blood Types.
The ABO Blood Group System. There are four major blood groups determin" rel="nofollow">ined by the presence or absence of two antigens – A and B – on the surface of red blood cells:
Group A – has only the A antigen on red cells (and B antibody in" rel="nofollow">in the plasma) Group B – has only the B antigen on red cells (and A antibody in" rel="nofollow">in the plasma). There are
eight different common blood types, which are determin" rel="nofollow">ined by the presence or absence of certain" rel="nofollow">in antigens, which are substances that can trigger an immune response if
they are foreign to the human body. Sin" rel="nofollow">ince some antigens can trigger a patient's immune system to attack the transfused blood, safe blood transfusions depend on careful
blood typin" rel="nofollow">ing and cross-matchin" rel="nofollow">ing.
There are 4 major blood groups determin" rel="nofollow">ined by the presence or absence of two antigens (A and B) on the surface of red blood cells:
Blood Group
Antigen
A
Has only A antigen on red cells (and B antibody in" rel="nofollow">in the plasma)
B
Has only B antigen on red cells (and A antibody in" rel="nofollow">in the plasma)
AB
Has both A and B antigens on red cells (but neither A nor B antibody in" rel="nofollow">in the plasma)
O
Has neither A nor B antigens on red cells (but both A and B antibody are in" rel="nofollow">in the plasma)
In addition to the A and B antigens, there is a third antigen called the Rh factor, which can be either present (+) or absent ( - ). In general, Rh negative blood is
given to Rh-negative patients, and Rh positive blood or Rh negative blood may be given to Rh positive patients.
The universal red cell donor has Type O negative blood type.
The universal plasma donor has Type AB positive blood type.
The same goes with the rh factor: if someone is negative, then they can't receive positive. O negative is the universal donor because there are absolutely no protein" rel="nofollow">ins
on the RBCs, which means that anyone can receive that blood without sufferin" rel="nofollow">ing rejection.
RH factor in" rel="nofollow">in blood types stands for "Rhesus Factor". Blood tests were performed on Rhesus monkeys and the Rh+ and Rh- factors were isolated. An antigen found in" rel="nofollow">in the
red blood cells of most people: those who have Rh factor are said to be Rh positive (Rh+), while those who do not are Rh negative (Rh-). What about the meanin" rel="nofollow">ing of RHD-
Rh blood group, D antigen . The rhesus complex is not just one antigen, but several, when someone is told to be Rh+, it usually refers to the D antigen (one of the
components of the Rh complex), because it's the most common, and the easiest to identify, however it's not the only one.
