Explanation:

Blood is classified into four different types: A, B, AB, and O.

Another way blood cells may be classified is by Rh factors. People who have Rh factors in their blood are called "Rh positive." People without these factors are called "Rh negative." Rh negative people form antibodies against Rh factor if they receive Rh positive blood.

There are also other factors to identify blood cells, in addition to ABO and Rh.

Your immune system can usually tell its own blood cells from those of another person. If you receive blood that is not compatible with your blood, your body produces antibodies to destroy the donor's blood cells. This process causes the transfusion reaction. Blood that you receive in a transfusion must be compatible with your own blood. This means that your body does not have antibodies against the blood you receive.

Most of the time, a blood transfusion between compatible groups (such as O+ to O+) does not cause a problem. Blood transfusions between incompatible groups (such as A+ to O-) cause an immune response. This can lead to a serious transfusion reaction. The immune system attacks the donated blood cells, causing them to burst.
