Blood Groups

Blood groups are very important in order to find out if a person can donate blood or receive blood in case of an accident or another disease. Almost everyone's plasma has antibodies that may not work together with another person's blood.

There are four main blood groups :

Type 0 is the most common blood group. In an emergency, type 0 blood can be transfused to anybody.
Type AB is the most seldom group. People with this blood group can receive any other blood in case of an emergency.
Type A can only be received by donors with A or 0.
Type B can only be received by donors with B or 0.
