Detailed explanation-1: -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-2: -This blood type is rare-only 4% of the U.S. blood donor population has type AB-positive blood. Patients with type AB-positive blood are universal recipients, meaning they can receive a red cell transfusion from any blood type.
Detailed explanation-3: -Preferred donation methods: plasma and platelet. Anyone can receive AB-plasma and platelets! Type AB-can receive negative types A, AB, B and O which is only 18% of the population.
Detailed explanation-4: -AB+ blood has both A and B antigens at the surface of the red blood cells, while other blood groups (A and B) only have one, or lack them altogether (group O). Because of this unique combination, AB+ donors’ blood can only be given to others with AB+ blood.
Detailed explanation-5: -The blood types must be compatible to avoid an ABO incompatibility reaction. For example: People with type A blood will react against type B or type AB blood. People with type B blood will react against type A or type AB blood.
