Blood Type O Is The Universal Donor

November 27, 2020

Type o is routinely in short supply and in high demand by hospitals both because it is the most common blood type and because type o negative blood is the universal blood type needed for emergency transfusions and for immune deficient infants. Blood types are characterized as positive or negative based on the presence or absence of a protein called rh factor.

Blood group types are based on proteins called antigens that are present on red blood cells.

Blood type o is the universal donor. This ability of it is due to the absence of a and b antigens on the surface of blood cells. Type o negative blood is theoretically capable of being transfused to any person. Type o negative blood can be used in transfusions for any blood type.

The universal donor blood type is o negative. This unique fact makes this type of blood o have a smaller risk to cause reactions to blood transfusions. The universal red cell donor is type o negative blood and the universal plasma donor is type ab.

Blood type ab is the universal recipient because it contains no antibodies and therefore will not reject any of the other blood types regardless of its antigens. This is because type o negative is the universal donor and type o positive is the most common blood type. A universal donor blood type means that supposedly anyone who has this type of blood can donate to anyone else regardless of blood type.

Universal donors are those with an o negative blood type. This means that people with blood types a b and ab have no antibodies to reject type o. Because of this it s sometimes called the universal blood donor type.

The universal blood type is o negative o. Anyone with this blood type can donate blood to a person who needs it regardless of their blood type. O negative blood can be used in transfusions for any blood type.

Hence a person with blood type o rhesus negative can donate his blood to everyone with all types of blood. Red blood cells from o donors can be transfused to anyone regardless of the person s blood type. Blood type o is the universal donor because it has no antigens on its rbc membranes.

Donors with type o blood have the unique power to help anyone in need of a blood transfusion. Blood group o is called as universal donor as it can be donated to any person having either a or b or ab or o blood groups. The blood type that is the universal donor is type o negative.

Type o blood is constantly in high demand in hospitals. For emergency transfusions blood group type o negative blood is the variety of blood that has the lowest risk of causing serious reactions for most people who receive it. Type o blood is the only type of blood group that does not have an antigen.
