Blood Type Test (ABO Grouping and Rh Type)

This Blood Type Test, also known as an ABO grouping and RH type test, determines your blood type (A, B, AB, or O) and whether you are positive or negative. Though made of the same elements, blood types are very different. Knowing your blood type can be useful should you choose to donate and potentially life-saving should you ever require a transfusion.

The Blood Type Test determines the four major blood groups:

1. Group A: Has only A antigen on red cells and B antibody in plasma (can donate to those in groups A and AB)
2. Group B: Has only B antigen on red cells and A antibody in plasma (can donate to those in groups B and AB)
3. Group AB: Has A and B antigens on red cells and neither in plasma (can donate to those in AB group but can receive from all groups)
4. Group O: Has A and B antigens in plasma but not on red cells (can donate to anyone but can only receive from Group O)
