Universal donor blood type
If you have blood type B, you have the B antigen.If you have blood type A, you have the A antigen.It is compatible with all A, AB, B and O positive blood types. O-negative blood is considered an all-purpose blood donor type. Type O blood is unique in that they have no antigens.They are O positive, O negative, A positive, A negative, B positive, B negative and AB negative. In addition to the universal receptor blood type, there are seven blood types.
If the immune system detects an antigen that isn’t on the body’s own cells, it launches an attack to fight it. An antigen is any substance to which the immune system can respond. It also discusses type-related or allergic reactions that can occur with blood transfusions.Īntigen The effect on blood cells determines the recipient’s response to blood transfusion. This article reviews how blood typing works and why donor blood types need to be safely matched to their recipients. In rare cases, receiving incompatible blood donations can be fatal. This attack can lead to serious problems, including kidney failure and shock. The immune system attacks donated blood cells instead of accepting them into the body. If a person receives the wrong blood type, the body sees it as a foreign body. Matching the correct blood type is the key to a safe blood transfusion or organ transplant. This means that AB+ people can safely receive blood transfusions from any other blood type. The universal recipient blood type is AB positive (also written AB+).
