17+ Blood Type Ab Antigens Images. Learn about blood typing and the rarest and most common types of blood and how they can impact your blood donation. The abo antigens are developed well before birth and remain throughout life.
Type ab is the only blood type whose existence is the result of intermingling rather than evolution and environment.
People with type ab blood are called universal recipients because they can receive any blood type. It is also known as fluid tissue present in blood vessels. This type contains no antigens. Blood typing is particularly important for blood transfusions, because certain antigens on blood cells can trigger a person's immune system to attack the donated blood.
