This is in contrast to type O negative, which is the universal donor. Type O blood has no antigens on the cell surface, so it doesn't provoke an immune reaction from any blood type. But, people with type O blood can only receive blood transfusions from another type O.


Universal recipients have type AB blood and can receive a blood transfusion from a person with any blood type.The immune system of a person with AB blood will accept blood from all possible donors, whether they have O, A, B, or AB blood.


Type "O" blood is called the universal donor because an individual with any other blood type can receive it. The the problem is, individuals with Type "O" blood can only receive type "O" blood.


The term "universal donor" means that this person's blood type can always be given to another patient, without the risk of a transfusion reaction. Similarly, "universal receivers" have blood types such that they can always receive blood from another patient without risk of these transfusion reactions.


At one time, type O negative blood was considered the universal blood donor type. This implied that anyone — regardless of blood type — could receive type O negative blood without risking a transfusion reaction. But it's now known that even type O negative blood may have antibodies that cause serious reactions during a transfusion.


Blood group systems. A complete blood type would describe a full set of 30 substances on the surface of red blood cells, and an individual's blood type is one of many possible combinations of blood-group antigens. Across the 36 blood group systems, 308 different blood-group antigens have been found. Almost always, an individual has the same blood group for life, but very rarely an individual&#...


Best Answer: Lab guy is absolutely correct: it is crucial to distinguish between transfusion of red cells and transfusion of plasma - these components are separated from each other. When you talk about O-blood as "universal donor" and AB-blood as "universal reciever", it is transfusion of red cells you are talking about.


When a blood transfusion or an organ transplant takes place, it is vital to know the blood types of the donor (who gives blood) and the receiver (who needs blood). There are a number of human blood group systems. Of these systems, the ABO blood group system and the Rhesus blood group system are the most important. In this system the presence or ...


O-negative Blood Type: Only seven percent of Americans have O-negative blood, as noted by an article on LiveScience. However, anyone can receive this type of blood. That is why it is known as the universal donor type. AB-positive Blood Type: AB-positive is the universal recipient type. Those with AB-positive blood can receive any type of blood.


The blood type that is the universal donor is type O negative. A universal donor blood type means that supposedly, anyone who has this type of blood can donate to anyone else, regardless of blood type. Type O negative blood is theoretically capable of being transfused to any person. Humans have four blood types: A, B, AB and O.
