Why is blood type ab+ considered the universal receiver? it has no antibodies that can attack the antigens on the red blood cells of the other blood types. it has no antigen on its red blood cells that can be attacked by the antibodies in the other blood types. it has no rh antigen on its red blood cells that can be attacked by the antibodies in the other blood types. it has no a and b antigens on its red blood cells that can be attacked by the antibodies in the other blood types.

Correct A). It has no antibodies that can attack the antigens on the red blood cells of the other blood types

Type AB blood is called as a universal receiver of blood because it does not have anti-A and anti B antibodies, so it can not attack or it can not agglutinate red blood cells of any ABO blood type. They have both A and B antigen on the surface of their Red blood cells but lack both the antibodies. In order to avoid the chance blood mis-matching it is better to check the blood type and Rh antigen.
