Detailed explanation-1: -Humans have 35 major groups or families of these antigens, as well as other minor groups, but consideration of two, the ABO group and the RhD group, is very important to ensure that a transfusion recipient receives compatible blood. The presence of antigens within these groups is what determines a person’s blood type.

Detailed explanation-2: -Group AB can donate to other AB’s but can receive from all others. Group B can donate red blood cells to B’s and AB’s. Group A can donate red blood cells to A’s and AB’s. Group O can donate red blood cells to anybody.

Detailed explanation-3: -The test to determine your blood group is called ABO typing. Your blood sample is mixed with antibodies against type A and B blood. Then, the sample is checked to see whether or not the blood cells stick together. If blood cells stick together, it means the blood reacted with one of the antibodies.

Detailed explanation-4: -Red blood cell antigens determine your blood group The antigens expressed on the red blood cell determine an individual’s blood group. The main two blood groups are called ABO (with blood types A, B, AB, and O) and Rh (with Rh D-positive or Rh D-negative blood types).
