A: Type A individuals can donate to other type A individuals and type AB individuals.O: Type O individuals can donate blood to anyone (because their blood has no antigens), but can receive blood only from other type O individuals (because blood with any antigens is seen as foreign).In other words, donations work as follows: So long as the blood they receive doesn’t have any antigens that mark it as foreign, their bodies won’t attack it. However, some people can still safely receive blood that isn’t their blood type.
If blood enters your system with antigens that you don’t have, your body will create antibodies against it. The ABO blood typing system groups your blood into one of four categories: According to Lab Test Diagnostics, hospitals will usually run a blood type test and, during emergencies, use Type O negative (the universal donor). If you receive the wrong blood type, your blood cells could clot, which can prove fatal. The emergency transfusion of O Negative blood is often done when there is no time to match the patient’s exact blood group. Persons with group O Negative blood are known as universal donors because their blood can be safely transfused to individuals with any of the other blood groups or Rh types. In case of an emergency, some people have to receive a sudden blood transfusion. Individuals with AB Positive blood are known as universal recipients because they can receive any one of the blood groups or Rh types in a blood transfusion. It’s important for each person to know their blood type.
