Blood is classified by type:
Blood is also classified by rhesus (Rh) factor, which refers to a specific antigen in the blood. If your blood has the antigen, you're Rh positive. If your blood lacks the antigen, you're Rh negative.
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. However, even type O negative blood may have antibodies that cause serious reactions during a transfusion.
Ideally, blood transfusions are done with donated blood that's an exact match for type and Rh factor. Even then, small samples of the recipient's and donor's blood are mixed to check compatibility in a process known as crossmatching. In an emergency, however, type O negative red blood cells may be given to anyone - especially if the situation is life-threatening or the matching blood type is in short supply.

A universal donor can only donate blood to recipients of different blood types because their blood lacks certain antigens that would cause a reaction. However, a universal donor can receive blood only from other universal donors, otherwise, they may suffer a transfusion reaction due to the presence of different antigens in the donated blood.
No. You would have to be a O blood type. That is the "universal" blood donor. The best kind.
To be a universal blood donor one must have O- blood type. A person with this blood type has blood cells with no antigens, so it won't react with other blood types, making it safe for anyone to receive the blood.
Yes, type O blood is considered universal because they can donate to all other blood types. It is also the most common blood type. They only can receive blood from another type O person.
A universal donor (blood type O) has blood cells with no marker proteins that another body can not reject. Blood type AB, the universal receiver has all the marker proteins, so it can identify blood of any other type as its own.
Blood group O is known as the "universal donor" because it has no antigens on its red blood cells and can therefore be safely given to any blood group. Blood Group AB is known as the "universal recipient" because it has no antibodies in its plasma and so can safely receive blood from any other blood group.
O- blood used to be considered the universal blood donor but now medicine knows that there are other factors in the blood that can cause rejection from the body.http://www.mayoclinic.org/tests-procedures/blood-transfusion/expert-answers/universal-blood-donor-type/faq-20058229
Type AB . AB is the universal recipient and it is the most rare blood type only 3% of people have it. I know this information is correct I just had a test on blood types and I got 100% hope this helps
compadibility with other blood types
Type A blood is considered a universal donor because it lacks the antigens that can trigger an immune response in recipients with type B or type AB blood. This means that type A blood can be safely transfused into individuals with these blood types without causing an adverse reaction.
Theres AB blood, B blood, A blood and O blood. O blood is considered a universal donnor because it has no specific code thing to it, so other blood types dont clot to it. If you mix other blood types together, you get blood clots and you can die. For example, mixing A blood with B blood will cause a blood clot. Hope this is helpful!
If you have type o negative then you are the universal donor and could donate to any other blood type. If you have o positive then you would be limited in what blood types you could donate to.
